This is a new breed of sock that is perfect for that spring and summer look of going sock-less in your loafers, top-siders, or driving shoes: a "no-show" sock that slips over your toes and the bottom of your heel to add a comfortable and absorbent layer between your bare feet and the insides of your shoes. These are especially recommended if your feet get hot and sweaty inside your loafers. 77% Pima cotton/21% nylon/2% spandex with a silicone gripper at the heel. Made in Italy. Fits shoe size 7-12.
