The leather lined, contoured cork footbed will mold to the shape of your foot creating a custom footbed that supports and cradles you each and every step. Raised toe bar is designed to encourage the natural gripping motion of your feet, exercising your legs and aiding circulation. Neutral heel profile and deep heel cup keeps the natural padding of your foot where it belongs, under the heel, distributing your body weight more evenly.
