What Our Gearhead(R) Experts Are Saying:"I wore these inside my river shoes on a cold shoulder-season run and immediately noticed the difference. They added just enough warmth without cramping space, and the grip on the sole helped when I had to step out on slick rocks."Cold water has a way of creeping in fast, especially when space is limited and bulky footwear isn't an option. The Neoprene Socks from Immersion Research give us a simple solution for staying comfortable when the river runs cold and every bit of warmth matters. Built with soft 2mm neoprene, these socks trap heat without adding bulk, so we can slide them easily into river shoes or wear them solo in low-volume boats. Glued and blind-stitched seams help keep water intrusion minimal, while the silicone grip on the sole gives us better footing on wet surfaces when we step out mid-run.
