These are decent water shoes. They stayed on in a medium surf, protected the bottoms of my feet while I was climbing up so sun-toasty lava rocks. The yellows ones are nice and bright, making them easy to see on the beach. Now, having said that: rocks and sand immediately gravitated to the inside of the shoes once wet. This was a miserable experience. Then the soles became unglued almost immediately, which made for a slippery or uncomfortable water shoe until I pulled out the soles.  This left behind glue residue which then trapped sand in it and made for gooey sand paper. For the price, its not horrible, but I'd never wear these shoes near sand or gravel again, which has rendered them completely useless. Since the sand and gravel trapped in the glue is bits of coral and lava rock from Hawai'i,  I might incur the wrath of Pele, maybe not worth saving $2...
