Smartwool PhD® Run Light Elite Crew Socks (Charcoal)

Our PhD® Run Light Elite Crew socks use targeted cushioning where runners need it most: on the ball and heel of the foot. We packed our most technical socks full of smart features like our 4 Degree™ elite fit system, activity-specific mesh ventilation zones, and Shred Shield™ technology to help reduce wear from toes. Their crew height helps provide additional protection against road and trail debris.—making this men’s running sock ready for anything.
