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.
