Using AIS: technology (Anatomical Interface System), the tetratsok is engineered to separate your toes with a thin, anti-friction membrane that is both light weight and breathable. Seamless in construction, the tetrasok forms to every contour of your foot and allows for true restriction free movement from your heel to five toes.
This patented anatomical 5 toe design strengthens feet and leg muscles, promotes healthier circulation, wicks away moisture more effectively from between toes and completely emliminates skin on skin contact ... thus preventing blisters from developing.
