The NRS Hydroskin Socks will protect your feet and keep them warm in the water without the bulk of a heavy neoprene sock. NRS HydroSkin Socks are the ultimate wetshoe liner and they work great with sandals too.The 0.5-mm neoprene core insulates and protects.

NRS’s Hydroskin Socks Feature:

4-way-stretch PowerSpan™ outer layer gives you enhanced mobility and greater durability.
The ThermalPlush™ inner lining increases insulation, repels moisture and dries quickly.
Titanium laminate adhesive aids body heat retention without adding bulk.
DWR coating forces water to “bead” and roll off the material, reduces evaporative cooling.
Color: Black

I was kindly sent a pair of NRS Hydroskins by Rapid Kayaks and I have used a pair of these for quite a while. They are simply superb. For my size 10 feet the XL size is perfect. They are constructed to fit the shape of your feet and provide a close but comfortable fit. Super warm and perfect for wearing with or without a dry suit.
