GO Traveling, GO Diving, GO Snorkeling ? with the GO fin. This brand new travel fin combines the fitment benefits of an open heel fin, with the comfort and barefoot freedom of a full foot fin. The GO is lightweight yet virtually indestructible, plus it?s a fast and nimble performer in the water. The replaceable self-adjusting bungee heel strap allows for a versatile fit. The strap also makes it easy to don and doff the fin, and it fits comfortably against a bare heel, although the GO will also accommodate neo socks for divers who prefer a little extra foot protection. It?s also designed to fit easily in IATA carry-on compliant luggage, making it the ideal fin for divers, snorkelers and swimmers who enjoy traveling the world.
