These are some quick slip on water shoes. They have a sole on the bottom thick enough to protect your feet. Yet not so thick that they are heavy. The rest of the shoe is a spandex mix material so they strech to fit and hug your feet. Thin and lightweight and quick drying. They are great for any activity outdoors or in the water. Or even indoors or at a pool or shower. #RankBoosterreview #Sponsored #LJCCQ https://www.amazon.com/Barefoot-Swimming-Lightweight-Anti-skid-Exercise/dp/B0748LCZ48
