No matter how far or how fast you’re running, the Smartwool Run Targeted Cushion Socks will provide breathable comfort. Made from a Merino wool blend, the fabric is soft, odour-resistant, & enhances temperature regulation. Ventilated mesh zones improve breathability further while the Virtually Seamless Toe eliminates chafing. Extra padding on the ball & heel of the foot ensures protection in high-impact areas.
