I've used mine three time and worn through the sole already. I get they're not made for walking around in for long, but I'm not taking them off every time I put my foot down. Also they're sized small. I have size 11 fett and got L should have got XL as the zipper keep open at my calf. Some sort of retainer here would help as the shoe part seems to be the correct size. Wouldn't get another pair.
