The Redington Men's Wet Wading Sock is a neoprene sock for fly fishing. The summer is hot, so why not ditch the hot and heavy waders and wade in shorts, wading socks and your wading boots? Much cooler, much easier, yet with plenty of protection. The three and a half millimeter neoprene provides warmth to your toes against cold river temps, as well as keeping feet dry. The gravel guards roll over the top of your boot, keeping tiny rocks and pebbles out. Fish on.
