These midweight crew socks provide insulation without overheating. The dynamic toe cup fits the natural shape of the toes to prevent chafing. A Y-shaped heel lock creates a deep pocket to keep the sock in place and maintain its shape. The full contact cuff hugs the leg for all-day stability. The socks have medium-weight cushioning around the foot, ankle, and lower calf to absorb shock and reduce pressure points. Color-coded toe seams indicate style and size.
