Because you don’t have two left feet, Keen built their socks with left-and right-specific fits for custom comfort. The Daily Lite Crew Socks have breathable comfort-zone panels that add cushioning and articulated support in all the right places. Other construction features, like contour arch supports and Y-heel pockets to keep them securely in place ensure these socks fit like a glove. Wunderseam in the toes' flex zones eliminates bunching and is seamless so you won’t even feel it. 52% merino wool, 41% nylon, 5% polyester, 2% spandex. Per pair. Made in USA. Size: L. Colors: Charcoal, Dark Earth.
