Whether they're sledding, skating, trekking, touring, or fortifying an igloo, the SmartWool Youth Wintersport Flower Patch Sock is up to the task. The 3 x 1 ribbed welt and flat-knit toe seam help keep feet comfortable all throughout the day. SmartWool on the inside of the sock delivers excellent moisture management, temperature regulation, and odor control. The medium, full-cushioned leg and sole help absorb shock for increased performance and durability. This over-the-calf sock is knit from a rugged blend of 66% Merino wool, 32% nylon, and 2% elastane fabric. Made in the USA.
