NRS Sandal Sock Black, M
NRS Sandal Sock Black, M, The NRS Sandal Sock gives you a bit of insulation for cold feet, without the bulky addition of a full-size wet sock. 2mm-thick neoprene adds a bit of warmth, while the fully taped seams reduce the flow of cold water. A HydroCuff creates a comfortable seal around your ankle and holds the warm water in, to increase warmth.
