On Performance Mid Sock, Karla Twilight/Navy M

Feet, primed 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. Temperature tech Made using 94% recycled polyamide, it features technical mesh paneling to keep temperature in perfect balance. Cooling when things heat up, warm enough that you won't get cold feet — whatever you're about to take on. Protective support The new edition of the Performance Mid Sock offers a lightweight and breathable design with a snug fit and subtle support. The cut is just high enough for a feeling of both protection and performance.
