Luxuriously soft and ultra-comfortable, the Geo Stripe Knee-High Sock wicks moisture away from the skin to keep feet cool in the summer, warm in the winter, and dry all year long. Uncrushable Merino lambswool is odor-resistant, itch-free, and thermally efficient. The Constellation Knee-High Sock features a double-welt top for stay-up comfort; cushioned sole for impact absorption; flat-knit toe seam for blister-free wear; and maximum ankle and arch support. Constructed from a durable blend of 51% wool, 44% nylon, and 5% Lycra spandex fabric. Made in the USA.
