Men's Run Zero Cushion Low Ankle Socks

Smartwool's durability construction for socks, knitting reinforcing yarns into the areas that wear out first. It builds in extra toughness at the high-wear zones so the socks last through long, hard use, without losing the fit or the soft feel of merino wool underfoot.

Smartwool's sock fit system, using panels of stretch and mesh to hold the sock snugly in place. It keeps the sock from slipping or bunching as you move, for a dialled-in fit that stays put, while the mesh zones add breathability and help guard against blisters.

Extra reinforcement in the toe of Smartwool socks, built to take the wear that usually shows up there first. By toughening the toe area, it stretches out how long the socks last, which matters most on high-mileage days and in stiff footwear like ski boots.

A flat-knit toe seam on Smartwool socks, made almost seamless to cut down the bulk and rubbing where the toes meet the shoe. The result is a smoother, more comfortable feel in the shoe and less of the friction that leads to sore toes on long days.
