For unbelievable warmth in the coldest conditions, you can't go wrong with the Browning Heavyweight Tall Wool-Blend Sock. Merino wool fabric naturally insulates and pulls moisture away from the skin, ensuring that feet stay dry and comfortable. The full-cushioned leg and foot help absorb impact for added comfort underfoot. The comfort toe seam ensures that the sock stays in place without bunching. The arch brace provides additional support where you need it most. 38% Merino wool, 38% acrylic, 23% nylon, 1% spandex fabric. Made in the USA.
