FitFlop sandals are designed to give your legs a workout while you walk. Their unique, safely-tapered midsole places varying densities of EVA under your feet each time you step to challenge the support and balance muscles of the foot and leg. Every step you take helps tone and trim your legs. They also help reduce joint strain and absorb shock. Easy to kick on and off, relaxing on your feet, and cute to boot, you may find you want to wear them everywhere!
