I have a pair of Do-Wins. I actually bought them in China in August whilst on holiday there (they weren't easy to find lol - lots of places selling basketball, badminton and table tennis gear and shoes, but finding a place that sell weightlifting shoes was like a needle in a haystack). Paid about 180RMB (slightly less than 30USD) - such is the advantage of buying locally!
Previously lifted in chucks, but I gotta say having a raised heel for squats is much better in terms of maintaining your lower back arch and tightness. I'm actually starting to like them for deadlifting too.
The Do-wins get a thumbs up from me.
