I wore this shoe maybe 4 times before the sole and body of the shoe started to separate. I was very active (volleyball, tennis, running) but I don't think that's a good excuse for his poor performance. Less than a month has passed and there are also holes on the side of the main body of the shoe. The material it's made of appears to be something like woven fabric, which made it difficult to make the shoe snug enough to exercise. It might be a sizing issue on my end. Ultimately you get what you pay for.
