Injinji smashes the notion that wearing socks with sandals is a fashion no no with their split toe series socks. Designed differently from other Injinji socks in which a space is created between the big toe and the other four toes for ease on and off. Built with AIS:technology. The Anatomical Interface System(AIS) is designed to separate the toes with a thin, anti-friction membrane that is lightweight and breathable. Seamless construction allows for a more natural restriction free movement from your heel to your toes, encouraging healthy circulation, and eliminates skin on skin contact between your toes to prevent blister from forming. A dual welted band with Injinji logo at cuffs keeps sock lifted for support. Arch support has 3 ply construction promoting circulation and non-slippage. A vector heel that is precision stitched for anti-slipping and accurate sizing. Anatomical 5 toe design prevents skin on skin friction and blistering, moisture wicking properties, and enables natural movement from heel to toes. Consists of 25% nylon, 70% Meacute;lange cotton, 5% spandex. Machine wash warm, line dry. Mini-crew cut design for a more athletic feel. Available in a 3 pair pack.
