That's been my impression with all running shoes over the last few years. They fall apart. I bought myself some nice Reebok shoes and they disintegrated. The sole is gone holes develop in the sides etc. I guess they make them lighter and thinner. I would prefer something that's a bit more durable but that doesn't seem to be an option.
Sure that happens. But in this case the quality was there - the uppers and attachment to the soles was top notch.
They look and feel awesome.
But the soles - the shoes' souls - are designed to disintegrate in real time.
