Protect your feet and keep them warm without the bulk of other wetsocks. NRS HydroSkin® Socks are the ultimate wetshoe liner. And, hey, they work great with sandals too! The 0.5 mm neoprene core insulates and protects, and a 4-way-stretch PowerSpan™ outer layer gives you enhanced mobility and greater durability. The ThermalPlush™ inner lining increases insulation, repels moisture and dries quickly. The titanium-laminate adhesive aids body heat retention without adding bulk. Their DWR coating forces water to "bead" and roll off the material, reducing evaporative cooling. There are anatomically shaped left and right feet, which offers superior fit and unmatched comfort while eliminating the guessing game. Pairing snaps help prevent you from hitting the river with only one sock.
