The usual water shoe issues. You can buy their equivalent at walmart and have the same outcome. Of course they work and last as just as long. I cannot remember what I paid for these but if it was more than $7 I definitely paid too much. The rubber probably cost more than the shoes were actually worth. The soles slide out. After a month or so of use, the bottom rubber started separating itself from the sock part. I stitched the foamy insole thing to the rubber from the inside trying to hold it in place (not easy as the shoe had to be turned inside out). After repeatedly stabbing myself in the finger with a leatherworking needle (normal sewing needles hate going through rubber) too many times, I reassessed the situation and came to the conclusion that the foamy insole was just going to tear anyways, so I stopped. My handiwork lasted about a week. The drawstring is great. These will be tossed after this summer in lieu of something better for next year.
