When I first got these shoes, I was loving them.  They are comfortable.  They breathe well.  They are attractive.  Now for the main downside.  The soles are a hard plastic and broke in the middle of the shoe.  I don't use these shoes for work or anything hard.  Both left and right are broken.  I'm not happy and usually don't like to complain.  Now after only wearing these shoes a few times, they are worthless.  I can't return them because they are out of warranty.  I'm contacting Adidas.
