Performance Run Zero Cushion Ankle

Ultralight. Ultra-tough. All-in on comfort.

The Run Zero Cushion Ankle Socks are built for runners who demand performance with every step. Made from naturally breathable, odour-resistant Merino wool, these socks pair minimalist cushioning with maximum impact protection in all the right places.

Smartwool’s Indestructawool™ technology reinforces high-wear zones, while Shred Shield™ toe durability keeps blowouts at bay. A Virtually Seamless™ toe reduces friction, and mesh zones enhance airflow to keep you cool during tempo runs and long hauls. The 4 Degree™ elite fit system ensures a locked-in, no-slip feel, whether you're chasing a PB or out for a casual cruise.

Lightweight, fast-drying, and made for mile after mile of performance—this is Merino engineered for movement.
