Simms Merino Thermal OTC Sock

Built for cold days and long wades, the Simms Merino Wool Over-the-Calf Socks deliver heavyweight warmth, comfort, and durability that serious anglers can count on. Designed to perform inside waders or boots, these merino wool fishing socks naturally wick moisture, resist odor, and keep your feet warm and dry from dawn to dusk.

Crafted in the USA with an 81% merino wool blend, these Simms wading socks feature reinforced midfoot support, durable heel and toe zones, and a full over-the-calf height to prevent bunching and sliding during long days on the water. The combination of merino wool, nylon, and Lycra® spandex ensures a snug, supportive fit that stays comfortable whether you’re hiking into a backcountry stream or standing knee-deep in icy winter flows.
