Performance Run Sock Mid

Built for runners putting in real daily mileage, the Performance Run Sock Mid is our go-to training sock for road and trail alike. A mid-cut design with targeted cushioning under the heel and forefoot keeps hot spots and slippage from killing your run, while the anatomical fit holds everything in place over long efforts.

• Mid-cut height adds ankle coverage and cuts down on debris entry whether you're on pavement or dirt
• Targeted cushioning zones under the heel and forefoot take the edge off impact without adding bulk
• Snug anatomical construction minimizes bunching and in-shoe movement — especially important on longer runs
• Solid daily trainer sock for high-mileage runners who need reliable performance in Southern heat and humidity
• Available in Black/Eclipse and White/Glacier in XS through L — works with On footwear or any performance running shoe
