The Superfeet Run Cushion High Arch Insoles offer a deep heel cup and higher arch that naturally flexes with your foot as you run. This insole uses Adaptive Comfort Technology™ which adapts to your arch and allows for some flex to compliment your stride. There is soft cushioning in both the heel and forefoot for underfoot comfort and impact absorption. As an added benefit, the top layer features moisture-wicking technology and odor control to keep your feet dry and stink-free. These insoles work best for runners with medium to high arches.
