Not sure how these will hold up for the long haul, but I bought them before a cruise to use as dual duty bedroom/pool shoes. COMFY! Did not wear on the beach or actually into the pool, but they were so lightweight, easy to pack and stretchy that I got a lot of use out of them. Okay over little "no show" socks too for extra comfort when I was just running around the cruise ship. Good grippy bottoms. Rinsed and dried quickly and easily. I did run them through a quick wash cycle in my home machine when they arrived to get rid of the new plastic smell. I'm a tenderfoot and do not like to go barefoot, so I live in flip flops. These were a nice break from the "between the toe" shoes - also super quiet when scuffling around in the cabin and on deck.Wore these on my trip to Jamaica. Although I loved the style and fit they are cheap and did not survive my Dunn's River excursion. I gave it a 3 star because I did like them and would problem buy them again but would use them for a regular water park activity and not for any rugged activities.A bit snug, which you should keep in mind when ordering but otherwise exactly as advertised. Love the happy color.No need to upside at all. These are one of the most comfortable water shoes I bought. So easy to slide on and off. I can't say enough. These are excellent for a water park or the beach...They are comfortableI loved the color and the weight. There is nothing I didn’t like. I think I might order more.Fun.This item is described as stated and does just what it suppose too do.
