Run Zero Cushion Ankle Socks

Some run socks disappear on your feet. These are built to earn that right. The Smartwool Run Zero Cushion Ankle sock is made for runners who value precision, durability, and comfort mile after mile—whether that’s a quick weekday loop or a long training block that keeps stretching longer.

Merino wool regulates temperature and resists odour naturally, keeping feet comfortable across changing conditions. Indestructawool™ and Shred Shield™ technologies reinforce high-wear zones, so these socks don’t give up before you do. A women’s-specific fit, Virtually Seamless™ toe, and breathable mesh zones create a locked-in feel with zero bulk and zero distractions.

Light, fast, and quietly tough—this is a sock built to keep pace.
