Men's Heavyweight Merino OTC Wader Socks Dark Gray Size Xs Wool/Merino Orvis

From Orvis

Fact: cold feet ruin days, so we've taken the heaviest weight merino wool fiber contents we could find and built winter-ready, over-the-calf warmth in the OTC Wader Sock, tested in conditions that would have less-committed anglers inventing excuses. Given their heavyweight, thick nature, gone are the days of doubling up socks in attempts to stay warm-these are the socks built to keep you in the game all day. Because they're patterned after the contour of our wader booties and boots, expect a seamless fit with reinforced zones in problem abrasion areas like the heel, toebox, and the top of your ankle where wading boots end. Ribbed arch eliminates bunching and ensures comfort.
