The Flipper Slipper fin sock by Body Glove is for divers and snorkelers who do not like the heavy wetsuit boots. Light weight and quick drying, the slipper fin sock takes up little room in your equipment bag. Divers on vacation will be able to put on a dry pair of socks when the standard boot is still wet from the day before. The Flipper slipper wet suit sock can be used with open heel and closed heel fins.
