Xtratuf's Riptide boat shoes feature three-layer mesh construction, which dries quickly, allows water to move in and out of the shoe, and blocks sand and debris. The perforated polyurethane/EVA insole promotes comfort and does not absorb water. Riptides also come with nonmarking, slip-resistant outsoles. Available in gray/orange and black/white for men (sizes 7 to 14), and in blue/white and brown/pink for women (sizes 6 to 11). Riptides cost $80.
