Had so far always K-Swiss shoes bought and had previously always satisfied. Ok, priced shoes were always around 100, -. These here are cheaper and I think it shows. This starts with the fact that the sole is not really flat and even, when it turns right shoe so very right that you realize that while running. So I'm always wrong on his right shoe. The insole has strange material, you sweat easily (which I did not have otherwise, not even shoes I own for years). In addition, the rear part of the shoe is constructed also fail. Normal has since a flap I say now that so easily goes up. This is so that the Achilles tendon does not rub back and hurts. Here that is not so, that is while running rubs the pretty doll and longer distances are not in it. Maybe I've only got a B-goods model, can be natural. Positives: The design is sent, typically K-Swiss precisely.
