I have a pair of Wei Rui Challengers. They’re a good shoe but not produced anymore. They’ve been replaced by a similar model but I don’t recall the name.
All of my training until just recently was done outside in all kinds of weather, and I think that might have degraded the material slightly because there is a small separation of the sole at the toe of the right shoe only. I would also try catching small plates with my foot as I dropped them (like you would catch a soccer ball) so they didn’t chip the cement patio, so a few bad bounces might have contributed to the separation.
Also, there is a small crack in the leather, several millimeters long, on the inside of both shoes where they bend when I’m on my toes. Again, I attribute that primarily to training outside in all elements, and to common everyday usage. All in all a good shoe though. Size was right on.
