Comfortable to Wear
Size: 11.5-12.5 Women/10.5-11.5 Men, Color: 2c-1172 Watermarks
These are easy to put on and extremely comfortable. The material seems thicker than my old water shoes, so should last longer. The soles provide good grip, even in a swimming pool, which makes them ideal for use in activities like water aerobics. The color flashes on the shoes make them interesting and more appealing than plain black. Highly recommended

Comfy Pool Shoes
Size: 11.5-12.5 Women/10.5-11.5 Men, Color: 1a-stripe Black-2
I’ve had these pool shoes a couple of months now. Here are my thoughts. Pros: Inexpensive, comfortable, fit well, dry fast, protect feet for you pool joggers. Cons: The inner sole gets loose, the material around the toes breaks down. Bottom line: For the money they’re worth it. Just don’t expect them to last a long time.

Love these. Good quality. Wore these to the beach and in the water on vacation and also wear them several days weekly to local pool. Very comfortable.

Wide toe box
The color is pretty on these water shoes. The toe box on these shoes is wide which collects water making it difficult to use them walking for exercise in the water. I bought these specifically to keep my feet protected. The sole is the perfect thickness needed but can’t use them for what they were bought for.
