The sock that made a name for itself from the Pacific Crest Trail to the AT. "Must pack" durability meets undeniable comfort in a Full Cushion sock that absorbs the rigors of the trail. These men's boot socks average 11 inches from heel to cuff, meaning they'll show about 5 inches above a standard hiking boot. A performance fit ensures no slipping, bunching, or blisters for peak hiking comfort. We close every toe seam using our True Seamless™ Toe technology for an ultra-smooth, undetectable feel. Reinforced footbed and Achilles cushion improve comfort and longevity. Merino Wool is at home on the trail, naturally moving moisture to keep feet fresh and dry in all weather. Our all-season weight, midweight socks thermoregulate to wrap feet in steady comfort when temperatures change. Midweight with Full Cushion - High density cushioning throughout the entire sock for comfort and performance. True Seamless technology for an ultra-smooth, invisible feel. Boot Sock Height - Sits mid-calf for added protection and warmth. Composition - Knit with 66% Merino Wool, 32% Nylon, 2% Lycra Spandex. Fast-action wicking pulls moisture away from skin, preventing sweaty, stinky socks.
