Features:

• Fit in focus - The pattern at the arch triggers sensory receptors to prime your feet for the run while Swiss engineering keeps the sock firmly in place. Expect improved fit and improved quality for performance standards that don't slip.

• Any weather - Made using 100% recycled polyester, technical mesh paneling balances temperature: cooling when things heat up, warm enough that you won't get cold feet — whatever you're about to take on.

• Support when you need it - In an improved ultralight minimalist design made using recycled materials, the new Performance Low Sock is anatomically shaped to hug the foot for gentle support.
