Cheap straps

A few months ago my boyfriend and I both purchased the Huarache air in black. He did not even wear his long and then the strap broke off at the back. At first I thought maybe it was the way he handled his sneakers. Well not long after him whilst walking to the bus stop from work, mine broke. I didn't even wear mine alot. But what bothered me at first was the sole came loose in front and I am not an active person where you can say that it is wear and tear. I mean I have always purchased nike, as the product last long. I could wear a pair of sneakers for years and they would still look good. I am dissapointment by this cheap quality that we received. I mean paying over a grand for a pair of sneakers is no childs play, quality is the least one would expect.
