Based on previous reviews, I ordered a size more to choose from. But it was totally unnecessary. I actually 37 and the size 37/38 fit already - actually.
The shoe is in the ball area actually held a bit narrow (due to the removable lining). For much too long for the size but. In addition, the heel is very broad. This one slips when walked in the shoe up and down, resulting in the long run to bubbles. The zipper is indeed actually very practical, thus the shoe but not for people with narrow cuffs. There is no possibility here to adapt somewhat.
Big plus is but in fact the removable lining. Especially for people who sweat heavily positive. Therefore, at least two stars.
