These water shoes fit perfectly and were perfect for my time in Costa Rica. I wore them hiking to waterfalls and was so grateful to have a sturdy sole for all of the rock climbing. I wore them all day while at the beach and swimming in the ocean. They were wonderful for rafting and wearing in the hot springs. The only complaint (and reason for 4 stars) is that the rubber tab on the top would rub against my leg so I had to cut it off and then it was fine. Other than the tab, I would definitely recommend!
