Have your best run or walk possible with Superfeet Run Support Medium Arch. Superfeet Run Support Medium Arch insoles are 20% thinner than Superfeet RUN Comfort insoles for a slim, versatile fit and feel in your shoes while also increasing comfort and efficiency during your run. The insoles have a deep heel cup that, combined with a gel pod, positions and cradles your heel to optimize natural shock absorption, disperse impact and minimize foot fatigue. A responsive EVOLyte® carbon fiber cap and two layers of AeroSpring Rebound foam combine to deliver exceptional comfort and smooth energy transfer through your gait from foot strike to toe-off. There is also a Moisturewick™ layer on top to help with odor control. The Superfeet Run Support Medium Arch is made for people with medium to low arches with its signature Superfeet arch shape that reduces stress on feet, ankles, knees and back by stabilizing the foot while running. Check out our guide on how to choose the right Superfeet insole if you are unsure of which one is perfect for you. These insoles are made to fit into moderate to tight-fitting running and walking shoes, even some without removable sock liners. You will still need to make sure to trim the insoles for them to fit perfectly, however. Plus, when you purchase a pair of Superfeet insoles, you are making a difference—Superfeet donates 1% of sales and 1,000+ volunteer hours to organizations working to shape a healthy future.
