I REALLY wanted to like these but unfortunately, the material is extremely cheap. I bought the blue metallic pair and within the first wear (about 8 hours at a sitting desk job in an office) the inner sole just completely fell apart. The material is actually black with a silver overlay on top (probably for the silver pair) and then a second blue metallic overlay on top of that. The blue layer just began to shred and peel off in thin strips and within a few hours most of the sole had turned black and silver.<br /><br />It isn't unwearable because all of the damage thus far has been confined to the sole which isn't terribly noticeable when worn. However, I noticed the uppers also beginning to crease which makes me worried the same thing will happen on top where it will be very noticeable.<br /><br />I gave these two stars because, so far, these still look ok when worn and I get compliments on them every time I wear them. But I thinking these will only last one summer before they are shot.
