The first time I got these, they were great. My Sifu picked me up a pair while in Calgary. They felt comfortable enough that I could walk around the house for hours-on-end and forget I was wearing them. Don't get these wet. I happened to walk across the street wearing these after some heavy rainfall, and they were ruined. That was clearly my fault, though. After purchasing three more pairs the same size, they didn't feel as good as the pair I had owned (and ruined) before. Perhaps I just need to wear them a little more to break them in. As long as you're not practicing on a slippery surface, you should be quite impressed.
