Our PhDᄄ Run Light Elite Crew socks use targeted cushioning where runners need it most: on the ball and heel of the foot. We packed these 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.
