The Injinji Tetrasok socks virtually eliminate blisters between toes with a seamless construction that protects each toe.
Constructed with Injinji's revolutionary seamless Anatomical Interface System (AIS) and Coolmax®, the tetrasok is the most technically advanced blister reducing sock.
AIS technology integrated four key features, that include an independent five-toe design. This approach of separating your toes with a Coolmax moisture wicking lining and a resistant nylon outer shell built with Spande-flex fibers creates a thin, anti-friction membrane that conforms to your feet for increased blood and air circulation.
Three Ply construction prevents sock movement while increasing wicking and circulation. Precision stitched VectorHeel prevents bunching and allows for a comfortable fit. CoolMax® fabric wicks moisture, dries quickly and breathes well, allowing you to benefit from cool, dry feet.
Content: 70% Coolmax, 25% nylon, 5% spandex.
