Our socks are unisex and fit according to shoe size. If you size up your running shoes, we recommend you go by your casual shoe size. Although the Lycra in our products contracts when it is exposed to water and heat in the wash, it has incredible properties, so Feetures! socks will stretch back to their original size after the wash.
Machine wash cold. Hang to dry. No bleach or fabric softeners. For best results, wash socks inside out.
