New grey now in stock!

Anatomical Interface System (AIS) is engineered to separate your toes with a thin, anti-friction membrane that is both lightweight and breathable. Seamless in construction, the tetratsok forms to every contour of your foot. This allows for true restriction free movement from your heel to five toes, encourages healthy circulation, and eliminates skin on skin contact between your toes to prevent blisters from developing.

Fabric content: 70% CoolMax, 25% Lycra, 5% Spande-flex
