When the waves are firing but the conditions are less than warm, fear not-- the Roxy 5mm Syncro Round Toe Booties are designed to keep your toes toasty in the coldest waters. They utilize Freemax superstretch neoprene for comfort and mobility, with a textured soft sole for added grip, triple glued and blind stitches seams to reduce water entry, and heel reinforcement for added durability.
