The accuracy Pass, or the sizes of the shoe were discussed here partly controversial. I have the size 44/45 and ordered me to say that the shoe fits very well. - WARNING: This is, however, the fact that I 10 (= 44.1 / 3) have shoe size. For someone who has exactly shoe size 45 (= 10.1 / 2), I guarantee that the shoes will be too small. It is extremely unfortunate that these shoes may be obtained only in double sizes (eg 38/39 or 44/45), and not in the exact individual sizes. Overall, the size is small, so that so someone will get with size 45 when ordering the shoe in 44/45 problems. The next-available size is 46/47, which could be a bit too large a "45er" in turn. - With regard to the quality of the shoes, I am completely satisfied. They have a robust + thick sole are, well made and very easy. The tightening is no problem and they have a good hold on the foot. Ideal for swimming in rocky waters with sea urchins & Co. - practical experience but I can not tell, because our holiday is yet to come.
