I had an exchange because I ordered 48 and received on the shoe 47 and it was stated when I ordered it stated 49 48. It would therefore appear that there is a difference of a size between the ordered product and the received product. Otherwise time and manner of delivery / flawless exchange. Repayments of very fast. Besides this size shift that requested an exchange, no complaints. Everything was perfect. See now on the long term, the quality of the product.
