Why Do Feet Smell Like Vinegar?

Written by Bianca Charles on June 1, 2021

Last updated March 20, 2024

The foot contains some 250,000 sweat glands. That’s a lot of glands, and a lot of sweat. No wonder foot odour can be such a persistent and prevalent problem with our feet. One common symptom may be that your feet smell like vinegar.

Do you ever wonder if your foot odour is unique to you, and if no one else deals with it? In fact, much of the population deals with Foot Odour in some capacity at some point in their life.

Foot Odour has a pungent smell and is often a sign of fungal or bacterial overgrowth. Foot odour is directly correlated with sweat. More sweat = more bacteria. More bacteria = more foot odour. It can be as simple as that. There may however be other underlying causes.

At Toronto’s Feet First Clinic, we tackle the topics we know are prevalent, but that you may be afraid to talk about. Have no fear. We’re equipped to handle all foot conditions so you can rest easy.

For a bit of DIY at home, below you’ll find an overview of foot odour, its causes, and what you can do to eliminate those stinky scents.

What does it mean when feet smell like vinegar?

Foot odour derives from sweat. The more your feet sweat, the smellier they are. It’s not the sweat that smells though: It’s the byproduct of the bacteria consuming your sweat. The more sweat there is, the more there is for bacteria to thrive on.

According to Healthline.com, “if your feet smell like vinegar, it’s most likely the result of propionibacterium breaking down your sweat and producing acid, which is similar to acetic acid (vinegar).”

Foot odour may also change. This change is usually attributed to one or several of the following factors:

Diet
Natural hormone cycles
General lifestyle

Some people may have stronger foot odour than others due to how much or how often they sweat. Excessive sweat is in and of itself a condition known as hyperhidrosis (excessive foot sweat is known as plantar hyperhidrosis). Sweat is considered “excessive” when the source is neither related to heat or exercise.

Does white vinegar kill foot odor?

Ironically, vinegar can kill the vinegar-smelling foot odour. White vinegar, since it’s an antimicrobial, can help kill the bacteria or fungi that contributes to your foot odour. You can do this by soaking your feet for 10-20 minutes in a vinegar bath: Simply add 1-2 cups of apple cider vinegar to warm water, and clean your feet before and after soaking with regular soap.

Why do toenails smell like cheese?

Smelly feet is a relatively generic symptom. The smell can come from anywhere. A common source is from your toenail(s).

Your toenails might give off a cheesy smell. Wait, what? That’s right. According to the University of Pittsburgh Medical Center, one type of bacteria, called brevibacterium, lives between the toes. It thrives in a damp, salty environment, and produces the cheese-like smell of feet. That same bacteria is used in the cheese creation process for Muenster, Entrammes, and Limburger cheeses. Yes, it’s true.

The bacteria can find its way into your toenails through sweat. Wearing shoes for lengthy stretches creates a dark, damp climate in which bacteria can thrive. Moisture buildup also softens the skin around your toenails, which makes it easier for bacteria to penetrate the toenail.

How do you get rid of sour smelling feet?

Now that we know why our feet smell, it’s time to get rid of the smell once and for all. There are a number of at-home preventative methods to eliminate foot odour. These odour-killing methods include:

Wash your feet daily with an antibacterial soap.
Soak your feet for 10–20 minutes in a large bowl or tub of warm water with a half cup of Epsom salt dissolved in it. Epsom salt helps eliminate bacteria by removing moisture from your skin.
Dry your feet after showering, bathing, swimming, or soaking. Consider wearing cotton socks and shoes made of natural materials that allow the moisture to evaporate. Consider changing your socks during the day.
Powder a small amount of cornstarch in your shoes to help keep your feet dry.
Over-the-counter (OTC) foot antiperspirant.
Swap your shoes regularly, and avoid wearing your footwear on back-to-back days to allow for proper drying in between use.
Spray the inside of your shoes with a disinfectant that contains a sanitizing ingredient, such as ethanol. If your shoes have removable insoles, take them out, spray them lightly, and then let them dry outside your shoe for 24 hours.
Use moisture-wicking socks. You want moisture and sweat away from your feet to help prevent and get rid of smelly feet. Investing in the proper socks can help your feet dry, and odour-free.

If foot odour persists, speak with your doctor about prescription medication for your feet.

While these methods will help with the smell and preventing bacteria buildup and fungal infections, they won’t eliminate an existing fungal infection – for that, you will need treatment from a foot specialist or doctor. Early intervention is key to effectively treating foot fungus, so if you suspect a fungal infection, it is best to get it looked at as soon as possible. Fortunately, the skilled chiropodists at our Toronto foot clinic can effectively treat various kinds of foot and toenail fungal infections.

Is smelly feet a sign of diabetes?

Smelly feet is one (of many) signs of diabetes. But foot odour doesn’t just affect those with diabetes – anyone can have it. However, if the odour persists after following the above measures and preventative methods, you may want to take the condition more seriously. Also, if you have diabetes, common foot issues – like fungal infections – can lead to serious complications: We recommend routine foot assessments for diabetic patients for that reason, and to book an appointment with a foot specialist immediately if you notice anything out of the ordinary.

6 Myths About Foot Odor

Foot odor is a frustrating problem; it goes to show that non-painful foot conditions can be as life altering as painful ones. There are many foot odour myths floating around the internet. In this article, we'll break down some of the most common foot odour myths, and give you the facts about foot odour causes and how to prevent it. 6 Myths About Foot Odour: Only People With Sweaty Feet Have Foot Odour Foot Odour Always Means You Have a Serious Health Condition All Foot Odour Smells the Same Going Barefoot Helps Eliminate Odour If You Have Foot Odour, you Aren’t Showering or Bathing Foot Odour Only Happens in Hot Weather Myth 1: Only People With Sweaty Feet Have Foot Odour Foot odour, also known as bromodosis, is the unpleasant smell that comes from the feet due to a combination of sweat and bacteria. The feet have numerous sweat glands, which produce moisture to regulate temperature and prevent skin from drying out. Plantar hyperhidrosis is the medical term for excessively sweaty feet. Sweat is a major contributor to foot odour and provides the moisture needed for it to thrive, however, other factors are also at play. The Main Causes of Foot Odour General bacterial buildup and everyday life! (wearing shoes all day long, etc). Fungal infections: Conditions like athlete’s foot can lead to odour as fungi produce waste products during growth. Diet: Certain foods, like garlic and onions, can affect sweat composition and lead to a noticeable foot odour. Health conditions: Conditions other than plantar hyperhidrosis can cause foot odour, including diabetes, particularly when ulcers and wounds omit a strong smell. Other conditions include thyroid disorders (they may cause excessive sweating) or kidney and liver issues. Footwear material: Shoes made from non-breathable materials trap even normal sweat production, increasing moisture and bacterial growth. Preventing foot odour often means choosing breathable, waterproof shoes. Hormonal changes: Puberty, pregnancy, or menopause can contribute to foot odour. https://www.youtube.com/shorts/1aaNATnXvWw Foot Odour Myth # 2: Foot Odour Always Means You Have a Serious Health Condition It’s true that one of the causes of foot odour can be an underlying health condition, but that doesn't mean it's serious. The most common cause of foot odour is a general build up of sweat and bacteria that you can tackle yourself. Foot odour is often caused by everyday factors like wearing shoes made from non-breathable materials or not changing socks frequently enough. In most cases, simple steps like improving hygiene, airing out shoes, or using foot deodorants (sprays, powders or creams) can help control the smell. While it's important to be mindful of persistent odour or other accompanying symptoms, the vast majority of foot odour issues are easily managed with at-home care and do not indicate a serious health condition. https://www.youtube.com/shorts/aFdZ042koME Foot Odour Myth # 3: All Foot Odour Smells the Same Foot odour can vary significantly based on several factors, including the underlying cause, personal hygiene, diet, and the type of bacteria or fungi present. For example, open wounds and sores will smell different than smelly, sweaty shoes. Here are some common smells: Sour: Often caused by bacteria breaking down sweat, resulting in lactic acid production. Musty: May be associated with fungal infections or warm, moist environments. Vinegar-like: Often linked to sweat and potentially neglectful hygiene. Ammonia: May indicate dehydration or a dietary imbalance. Rotten: This odour can be a sign of a more serious infection. Foot Odour Myth 4: Going Barefoot Helps Eliminate Odour While going barefoot might seem like a good idea for reducing foot odour, it can actually have the opposite effect in some cases. While it’s always good to air out your feet, going barefoot outside exposes your feet to various surfaces that may harbour bacteria and fungi. Walking on dirty or damp surfaces can lead to the accumulation of these microorganisms, potentially worsening foot odour. In fact, foot fungus (one of the most common causes of foot odour) is often caused by walking barefoot in public places. Additionally, sweat can still pool in the crevices of your feet without socks and shoes, allowing bacteria to thrive. Instead of eliminating odour, going barefoot may introduce new sources of smell. Wearing breathable footwear and moisture-wicking socks and changing them regularly is a much better idea. Myth 5: If You Have Foot Odour, You Aren’t Showering or Bathing This is completely untrue since foot odour is often linked to other conditions like plantar hyperhidrosis and fungal infections. Therefore, foot odour is is a symptom rather than a cause. It also often develops throughout the day, so you can shower every morning and still experience smelly feet when you get home at night. That said, you should pay more attention to foot-specific hygiene and clean your feet frequently. Check out this blog article on foot hygiene tips to learn what to do. Myth 6: Foot Odour Only Happens in Hot Weather Foot odour is commonly associated with hot weather, but it can occur year-round, regardless of the temperature. While warm conditions can exacerbate sweating and create a breeding ground for bacteria, factors such as personal hygiene, footwear choice, and lifestyle also play significant roles in foot odour. For example, wearing insulated shoes in fall or winter weather can trap moisture and heat, leading to odour even when temperatures are low. Additionally, individuals who sweat excessively—regardless of the season—are more likely to experience foot odour. Therefore, it’s essential to maintain proper foot care and hygiene practices throughout the year to prevent odour, not just during the warmer months.

How to Prevent Toenail Fungus: Tips from a Foot Specialist

There are two common fungal infections that can target your feet. For your skin, it’s athlete’s foot (tinea pedis), and for your nails, it’s fungal toenail (onychomycosis). Fun fact: Onychomycosis is the name for nail anatomy changes caused by contagious fungus, while dystrophic is the term for any other abnormalities that affect how your nails look or grow. Today’s blog will focus solely on toenail fungus. You’ll learn what it is and how to treat it, as well as some top fungal toenail prevention tips recommended by our Toronto chiropodists. Toenail Fungus Symptoms Sometimes toenail fungus is mild and barely noticeable. But fungal toenail can present more severely if you’re immunocompromised, such as if you have diabetes, or a senior. Keep an eye out for these common symptoms: Drastic changes in the nail’s appearance: it can look much thicker, have a yellowish, brown colour, and be very brittle and prone to cracks, despite thickening. Unpleasant odour coming from the nail: the smell is often reported to be sour or like cheese. The nail starts lifting off the nail bed: this is because debris starts to accumulate and lifts the nail up so it can’t reattach. Pain, swelling and bleeding in severe cases. Toenail Fungus Prevention: Foot Specialist Advice The most important fact to remember about fungal toenail is that it’s contagious. Since fungal infections spread easily in damp, shared spaces like pools, gyms, and shower rooms, the best defense is keeping your feet clean and protected! Here are some top, Toronto-chiropodist-recommended tips to remember: Follow a strict, yet fun and relaxing, foot hygiene routine. It’s a part of self care, after all! Wear breathable footwear. Opt for shoes made from materials that allow airflow to keep your feet dry. Change socks daily. Fresh socks prevent moisture buildup, which fungi love. Avoid going barefoot in public places. Use flip-flops or shower shoes to protect your feet in shared spaces. Keep your toenails trimmed and clean. Regular maintenance helps prevent infections from taking hold. Get a professional medical pedicure if you don’t have time to focus on nail care. How to Treat Toenail Fungus Once fungus has gotten a hold of your nails, it’s time to think about treatment and eradicating the problem. Unfortunately, you can’t do much to treat toenail fungus yourself at home, and you often need a chiropodist’s help. Luckily, treatments are easy to follow and non-invasive. Here’s what a foot specialist can do: Perform nail debridement to remove infected parts of the nail. Use prescription-strength topical antifungal medicine on the nail (it penetrates the actual fungus) Educate you on products you can use going forward to prevent re-infection, like the best moisture-wicking socks, shoes, foot creams, deodorants and more.

The Importance of Regular Foot Check-Ups: What to Expect During a Foot Clinic Visit

There are many at-home and natural remedies for foot pain that work, but there’s no denying the importance of foot exams with a top Toronto chiropodist. Some conditions require foot check-ups throughout the year and your foot clinic visits can make a big difference in not only your comfort levels, but your long-term health. Let’s take at what you can expect at a foot clinic appointment and why you should get your check-ups. What You Can Expect at a Foot Clinic This depends on if you’re visiting your foot clinic for the first time or are following up with a specific service, such as a custom orthotic casting and fitting or a medical pedicure. At Toronto’s Feet First Clinic, your first foot check-up—an initial foot assessment—helps determine your unique needs. It’s your chance to discuss any concerns so your chiropodist can tailor the care to what matters most to you. Many people schedule one if they have persistent foot pain, but you may also do it for diagnostic purposes, footwear recommendations and more. Why Schedule Regular Foot Check-ups? Regular foot care is mandatory if you have diabetes. Studies show that neglecting your feet and failing to visit your foot specialist may lead to infections, ulceration and limb loss. While they sound extreme and scary, chiropody services can help you prevent these problems. Chiropodist visits for diabetes include full examinations (particularly to assess for neuropathy), nail and skin care, wound debridement, and more. Some experts recommend coming in every 4-6 months, but this may be more or less, depending on your condition. Foot check-ups are also a must for anyone with arthritis, circulatory issues, a history of strain injuries like plantar fasciitis, chronic fungal infections, to name a few. They’re especially important as we get older. But really, anyone can benefit from a little foot TLC—whether you're on your feet all day or just looking to prevent future problems, regular check-ups help keep your feet healthy, pain-free, and ready to go wherever life takes you! An annual foot assessment is also a great preventative form of self care, like a wellness check for your feet. You don’t have to wait until you notice symptoms — assessments can catch early signs of the most common foot issues before they become painful.

Foot Care for Runners: Preventing Injuries and Maximizing Performance

Whether you're an experienced marathoner or an occasional runner, healthy, happy feet are core to your running success. After all, our feet are the unsung heroes that carry us through kilometres of training and races. Without proper care, our feet and body can only take us so far before we develop aches and injuries. Proactively caring for your feet can help prevent injuries and boost your performance. In this blog post, we dive into our top foot care tips for runners to keep your feet in tip-top shape. Choose the right shoes It all starts with the right pair of running shoes. Everyone's feet are different, so there's no one-size-fits-all. Make sure your shoes fit well—there should be about a finger's width of space between your longest toe and the end of the shoe. The best way to find your ideal shoe is to visit a specialty running store (like our Toronto foot clinic!) where they can analyze your gait and recommend a shoe that suits your running style and foot type. Replace your shoes regularly Another one of our top foot care tips for runners is to replace your running shoes when they wear out. Running shoes don't last forever. Generally, they should be replaced every 450-800km. Worn-out shoes lose their shock absorption, grip, and support, which can lead to injuries. Look for signs like flattened soles or uneven tread to know when it's time for a new pair. You may also notice wrinkles among the various areas of cushioning. Incorporate foot-strengthening exercises Strong feet are less prone to injury. Simple exercises like toe curls, heel raises, and foot stretches can help build strength and flexibility. Try using a resistance band to stretch your feet and calves, and don't forget to roll a tennis ball under your foot to relieve tension and keep things limber. You may also find a lacrosse ball effective for a more rigid plantar fascia massage. Pay attention to your running form Sometimes, foot pain can be traced back to improper running form. Ensure you're landing with your feet underneath your hips rather than over-striding, which can put unnecessary stress on your feet. If you're unsure about your form, consider working with a coach or getting a gait analysis to pinpoint any issues. Stretch and foam roll Stretching isn't just for your legs and back; your feet need love, too. Incorporate foot stretches into your routine, focusing on the Achilles tendon, calves, and the bottom of your feet. For example, do a calf stretch by standing on a step and letting your heels drop below the level of the step. Foam rolling can also help, particularly if you're experiencing tightness in your plantar fascia or Achilles tendon. Keep your shoes dry Blisters and fungal infections love a moist environment. Make sure your feet are dry before putting on socks and running shoes. Choose moisture-wicking socks designed to remove moisture from your skin to help keep things dry. This can prevent blisters and reduce the risk of fungal infections. Consider using foot powder or antiperspirant if you're prone to sweaty feet. For additional moisture prevention, buy two of the same pairs of running shoes and cycle them in and out. Longer durations between uses allow the cushioning to decompress and give your shoes more time to dry thoroughly. Listen to your body Our final foot care tip for runners is to always listen to your body. If you're experiencing persistent foot pain, don't push through it. Ignoring pain can lead to more serious injuries later. Rest, assess, and seek professional advice if needed. Remember, rest days are just as important as training days. They give your feet and body the time they need to recover and adapt to the stress of running.

How to Treat and Prevent Athlete’s Foot: Tips from Chiropodists

Athlete's foot is a fungus that infects the skin on your feet. Many people get it, and it can cause a lot of problems. Your feet may itch, turn red, and peel when you have it. This fungus grows best in places that are warm and damp. The good news is that you can treat and stop athlete's foot if you know what to do. Here are some tips from chiropodists (foot specialists) to help you keep your feet healthy and free from fungus. Treatment strategies See a Chiropodist Because of all the moisture buildup on our feet, fungal infections can grow out of control very quickly; they're stubborn and persistent, and once the infection gets under the toenail, it becomes very difficult to treat. In addition, over-the-counter anti-fungal medications are not very effective unless the infection is in the very early stages. That's why it's important to see a chiropodist as soon as you notice any symptoms. A chiropodist will debride and clean up any fungal growth on the skin and prescribe a topical anti-fungal medication to help nip the athlete's foot in the bud before it spreads to the toenails. Oral anti-fungal medications, while effective, are often not recommended due to their side effects. Often, topical prescription anti-fungal medication and persistence are the best way to go. Maintain a rigid hygiene routine Your feet and body will thank you if you keep the infected area clean and dry. Wash your feet daily with soap and water and dry them well between your toes. Fungus grows best in damp places, so ensure your feet are dry before putting on socks and shoes. If you're particularly prone to sweaty feet, you can also try an anti-bacterial foot deodorant like Gehwol's Foot Deodorant spray. This can help prevent Athlete's foot, and even treat it in its very early stages. Avoid scratching Scratching the infected spot can cause other bacterial infections. To soothe the itch, try using antifungal creams or powders. If the infection gets worse or spreads, talk to a doctor. Change socks regularly Choose cotton or merino wool socks that let your feet breathe and wick away sweat. Wear fresh socks every day and change them after physical activity or when they get wet. This helps reduce moisture build-up, which can worsen the fungal infection. Prevention Tips Avoid walking barefoot in public Athlete's foot, along with other fungal infections, are contagious and spread when skin comes into contact with an infected surface. Therefore, always make sure you are wearing some kind of protective footwear in public spaces - like flip flops or slippers - in locker rooms, communal showers, pool decks and gymnasiums. Stick to a foot care routine Clean your feet and dry them well between your toes. Also make sure you cut and clean your toenails often, as fungi can hide under the toenails. Just make sure you don't cut them too short, or you can get an ingrown toenail. Put on the right shoes Pick shoes that let air flow through them. Avoid (if possible) wearing the same shoes all day, every day, and ensure they're dry before putting them on. Use flip-flops or water-safe sandals in public spots like pools or gym showers to avoid touching infected surfaces. Clean Your Shoes Fungal spores can hang around in shoes, which will feed the infection. To combat this, spray your shoes and socks with antifungal and antibacterial products, such as hypochlorous acid, zinc oxide or zinc incoleate, and dry them out before you put them on again. You can use Gehwol Foot & Shoe Deodorant Spray in your shoes, or dust Gehwol Foot Powder into your socks. These products contain zinc oxide and zinc ricinoleate, respectively, which are great for maintaining a healthy environment in your shoes. You can find these products at our Toronto foot clinic. Keep personal items to yourself Don't let others use your towels, socks, or shoes, and vice versa. Fungal infections are contagious and spread through touching or sharing personal items with people who have a fungal infection.

Secondary Toenail: What It Is and How to Handle It

Whether they're discoloured, cracked, ingrown, curly, or on the verge of falling off, toenail anatomy can be fragile and our nails can do funny things. A less commonly discussed issue is a secondary toenail. Also known as an accessory toenail or petaloid toenail, a secondary toenail is a sneaky little extra nail twin that grows alongside or beneath the pinky toenail. This abnormal toenail growth can be concerning, so it’s natural to have questions. Signs You Have a Secondary Toenail It’s important to know the difference between an ingrown toenail and an accessory toenail. First, ingrown toenails can grow on any toe, whereas a secondary toenail appears on the fifth, smallest toe. Ingrown toenails are also far more common, and pierce the skin rather than growing alongside the nail. Secondary toenails are thin in nature and often don’t cause pain, infection or swelling like ingrown toenails do (although it is possible). Lastly, ingrown toenails form on the side of the nail unit, whereas secondary toenails grow underneath the proper nail. What Causes a Secondary Toenail? A secondary toenail is a rare phenomenon. It often makes an unexpected appearance after trauma or injury to the nail bed. You may notice your nail growing differently after stubbing or hurting it. Chronic pressure from tight shoes or less-than-perfect nail trimming can also coax this extra nail into existence. Do You Need Surgery For Secondary Toenails? Studies show that the treatment of choice for this extra pinky toenail is an excision, especially if it’s infected. A partial or total nail avulsion from Toronto’s Feet First Clinic may be the solution you need, but you’ll have to schedule a proper foot assessment to determine the best course of action. Treatment of accessory toenails targets the original toenail, not the second one. The second toenail should grow properly after the “main” nail is removed.
