Haven't tested them at the water park yet (which is reason for buying) but both my daughters have them all over the house worn, run and played and they say they are comfortable. They are also great for outdoor water play, they can even be worn in the park and regular summer play which is what I love the most. Don't waste money on shoes for just one purpose! My only complaint is that the sizing is a bit odd, my youngest daughter needed a larger size than her usual shoe size and my eldest daughter needed a smaller one. In addition, the ankle hole is very large, which makes it impossible to increase them (otherwise they will slip on the heel). I had to buy 3 sizes of each to find the right size but can't beat the free returns. I'm keeping the size for my oldest daughter to grow up and will buy a larger size for my other daughter if she performs well at the water park this weekend.
