Why High-Stack Running Shoes are So Popular

The HOKA trend is the rise in popularity of HOKA’s high-stack running shoes, or running shoes with cushioning, extra height, a high heel stack and a rocker sole. They aren’t the first popular running shoes trend, and they certainly won’t be the last. Although people exclusively associate this type of trendy running footwear with HOKA, many other brands like ASICS and Saucony make footwear with the same high-stack shoe technology. Today, we’re diving into why these shoes offer more than just style—they come with real benefits. But they’re not for everyone, so we’ll also cover who should steer clear of this particular design.

What are High-Stack Running Shoes? 

High-stack running shoes, often called “super cushioned” or even “chunky,” by those who don’t know the terminology, have transformed modern footwear design, having a great impact on design for many high-quality brands. Often attributed to HOKA for “starting the craze,” these shoes feature thick midsoles packed with advanced cushioning foam technologies that enhance energy return, provide sufficient shock absorption, and improve comfort over long distances.

Despite their benefits, high-stack shoes aren’t without controversy. Some runners prefer lower-profile shoes for better ground feel and stability, while others find high-stacks beneficial for injury prevention and endurance. Their chunky aesthetic has also sparked mixed opinions—some love the bold look and the added height without having to wear a true high heel while others see them as clunky.

High-Stack Shoe Technology

The defining feature of high-stack shoes is their thick midsole, which can measure over 40mm in some models. These midsoles use lightweight, resilient foams such as Pebax or EVA blends that provide exceptional cushioning while maintaining responsiveness. The goal is to reduce muscle fatigue by absorbing more impact, allowing runners to maintain performance with less strain on joints and soft tissues.

Another key factor in their performance is the rocker geometry, rocker bottom shoe or rocker sole—curved soles designed to promote a smooth heel-to-toe transition. This feature helps conserve energy, particularly during long runs, by reducing the work done by the calves and ankles.

The Benefits of High Stack Shoes

High-stack running shoes offer several benefits for foot health, especially for individuals dealing with arthritis, diabetes, and metatarsalgia. Here’s a breakdown of their advantages:

  • Enhanced Cushioning: High-stack running shoes feature extra cushioning, which absorbs shock and reduces impact on the feet during movement. This is particularly beneficial for people with conditions like arthritis, where joints are sensitive to pressure and movement.
  • Pressure Redistribution: The additional cushioning and rocker sole work together to redistribute pressure across the foot. In the case of diabetes or metatarsalgia, this can help alleviate excess pressure on specific areas of the foot, such as the forefoot or metatarsal heads. For those with diabetes, reducing pressure can help prevent the skin damage that leads to ulceration, as it lowers the risk of tissue damage and enhances comfort. (However, people with diabetes and balance issues may wish to avoid rocker soles – more on that later).
  • Joint Protection: The rocker sole limits the motion of foot joints. This helps manage conditions like osteoarthritis and hallux limitus (big toe arthritis). By restricting unnecessary movements, it prevents excessive strain on the joints, protecting them from further damage. This is especially useful for the big toe joint, where excessive motion can lead to increased pain and discomfort. It’s also highly beneficial for people with high arches. People with high arches tend to experience joint rigidity (particularly hallux limitus). The rocker sole offsets the restricted mobility.
  • Improved Biomechanics: The curved design of the rocker sole encourages a smoother, more efficient gait. The shape propels the foot forward with each step, facilitating a natural walking motion and reducing strain on the joints. This is particularly beneficial for those with ankle, midfoot, or big toe arthritis, as it helps maintain normal walking patterns without overloading the affected areas.
  • Pain Reduction: Rocker soles are especially effective in reducing pain associated with conditions like hallux limitus and metatarsalgia. By minimizing motion at the big toe joint and redistributing pressure under the ball of the foot, these shoes can significantly reduce the discomfort felt during daily activities like walking or standing.

When to Avoid High Stack Shoes

Here are some individuals who might want to avoid them or consult a foot care professional, like a chiropodist or a podiatrist, before wearing them:

People with Balance Issues

The rocker sole on high-stack shoes can make them less stable for individuals who struggle with balance or proprioception (awareness of body position). Those at a high risk of falls, such as elderly individuals or those with severe neuropathy, may find that the rocker sole from stacked heels throws off their balance.

People with Diabetes

Complications from diabetic neuropathy can lead to balance issues. Therefore, while the cushioning of a stacked heel is great for addressing joint issues, the “rolling” effect of the rocker sole is not suitable for people with diabetes.

Individuals with Ankle Instability

The increased midsole height and curved design can reduce ground feel and make it easier to roll an ankle, especially on uneven surfaces. People prone to ankle sprains or with a history of ankle instability might be better suited to lower-profile shoes with more lateral stability, or stability shoes with posting in the midsole (like the ASICS Gel-Kayano), which is constructed to cradle the foot and control ankle movement. In shoes like the ASICS Gel-Kayano, even though there is a stacked heel, the foot actually sits below the sole to provide stability.
