Crossamphibian Swift 2 Water Shoe Lightweight and water friendly, these shoes are made from a breathable mesh that lets water flow freely and keeps debris from sneaking into your shoes when you're on the move. A specially designed sole offers traction on everything from sandy trails to slick rocks as you search for critters in the tidal pools. Size 10 Very gently used, as my husband bought for a trip and only wore 3 times.
