NRS Wetsocks That in-between season when the air is warm but the water hasn't caught up yet calls for a little thermal help underfoot, and the NRS Wetsocks hit the sweet spot between bare feet and a full neoprene bootie. At 2 mm with titanium adhesive that reflects your body heat back to you, these socks add meaningful warmth without the bulk of a heavier wetsuit sock. Three-piece construction with flat-locked seams hugs the contours of your foot smoothly without bunching or creating pressure points inside a wetshoe or sandal, and anatomically shaped left and right feet deliver a genuine fit rather than a one-size-fits-both approximation. They work equally well worn alone with sandals on a cool morning paddle or layered inside wetshoes for added warmth and cushioning on longer days on Canadian lakes and rivers. Pairing snaps keep the socks together in your gear bag so you're never heading to the put-in with only one.
