Many reviews of runners praise the shoe very! That is why I ordered the shoe and looked forward to the first race. After a few kilometers then constantly feel that the right shoe has a bump or a hardening in the sole. The feeling of running on a stone. Shoe sent with this note to the retailer back and claimed as material defect. After about 14 days the shoe unrepaired get back. On the grounds that an exchange after use is not possible. Again tried to contact the supplier. One is through Amazon and e-mail. No answer received. Next try to take the A-to-Z Guarantee claim in Amazon. Despite the description when the guarantee will: "You have received the items, but this was defective, damaged or did not correspond to the description given by the seller in the supply." Amazon rejects from the warranty claim. Empty advertising promises. Thus, now a broken shoe for about 140,00 at home and probably erstreiten only the chance for a lawyer a rectification.
