On Performance High Sock Black/Shadow

Performance Mid Sock are lightweight and breahtable training socks for women from On. Cooling when things heat up, warm enough that you won't get cold feet — whatever you're about to take on. The pattern at the arch triggers sensory receptors to prime your feet for the run, while Swiss Engineering keeps the sock firmly in place for performance standards that don't slip.

Fabric: 94 % polyamide, 6 % elastane
