I bought these to use when we visit Hawaii in October. They have no support, but the thickness of the sole seems like it will protect from rocks, sand, creatures and lava we may encounter. They are snug to get into, so if you have a thicker foot, they might be quite a challenge. Once in, they fit well. I believe most of the sand and rocks will stay out, while the water will leak out. Looks like a good, sturdy product.
