That this product came from GB, the delivery time of less than a week is absolutely top, plus the free delivery. Could not be better. The shoe itself is like a second skin on the feet and fits (contrary to other reviews) in my normal shoe size perfectly. Size 45 is size 45, I do not know why the other buyers have made such different size specifications, I can not confirm absolutely. My running mate the same shoes has also ordered in its normal size and they fit easily. From me an absolute buy recommendation, I can only say thank you for this great price / performance ratio.
