TA4 Thin Air Performance Socks - Blue

With OS1st's groundbreaking Skin Thin construction, the TA4 Thin Air Performance blue socks offer performance support without compromising comfort, thanks to their extra-thin design. Designed as the world's thinnest running socks, the TA4 Thin Air feature four-zone light compression. Despite being ultra-thin, they don't lose their cushioning, and the socks provide full protection against friction and blisters. They don't fold or bunch inside your shoes. A deep heel pocket and a high band that wraps the ankle keep the socks from slipping off your feet.
