Looking after your feet, in and out of the water, the Gul GBS Swim Socks are an essential piece of swim kit for any open water swimmer. Made from 3mm thick neoprene, the glued and blind-stitched (GBS) design helps unwanted water leaking in while the velcro ankle closure makes for a snug fit beneath or over your wetsuit. A neat touch is the protective reinforced printed sole for \\\'non slip\\\' protection, whilst providing additional abrasion resistance. Subtle but great for protecting your feet from hard ground, stones and sharp objects on the way to and out of the water.
