Smartwool Mountaineering Extra Heavy Crew Sock -s Men's

In stock

The toughest treks call for heavy duty gear. They call for guts. They call for the Men's Mountaineering Extra Heavy Crew Socks from Smartwool. Ankle and arch braces on this sock guarantee a secure and comfortable fit, and a flat knit toe seam prevents chafing and discomfort. The extra heavy cushion absorbs impacts on the trail, and it's designed for mountaineering expeditions. Best of all, of course, is the merino wool blend fabric. It retains warmth well in the cold, and it breathes well too for efficient thermal management. The fabric wicks sweat and dries rapidly, dispersing excess moisture away from the skin, and it's naturally antimicrobial. This prevents nasty smells and fosters a healthier foot climate. Frankly, there's no other sock we'd rather wear to take us to the summit.
