On Running Mens Performance High Sock in Black/Shadow

The standout performance running sock that always has you covered. A statement of intent for your run

• On Performance Socks combine a polyamide and elastane blend with technical mesh paneling. The mesh sections help keep foot 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.
• Your running sock might not win you the race, but it could lose you one if it doesn't perform. That's why we set out to see how much performance we could put into a running sock. Turns out, a lot. Like the pattern at the arch which triggers sensory receptors to prime your feet for the run. Plus Swiss Engineering to then keep the sock firmly in place. For performance standards that don't slip.
