Performance Run Sock High

Built for race day and hard training runs, this high sock from On is a solid choice for runners who hate dealing with blisters and bunching. Anatomical left/right construction with a seamless toe box keeps fit locked and wrinkle-free, while breathable mesh panels and moisture-wicking fabric handle Southern heat without turning your feet into swamps.

• Anatomical left/right fit — each sock is shaped for its foot, so nothing shifts, bunches, or folds mid-run
• Seamless toe box eliminates the seam-on-blister problem that kills long runs and race days
• Breathable mesh ventilation zones move heat and moisture out fast — a must in Southern humidity
• Targeted arch support adds just enough stability without the stiffness of a compression sock
• Available in Black/Eclipse and White/Glacier across XS–L — covers most foot sizes with a clean, minimal look
