1) The size is not correct at! I have about 42 1/2 shoes, and other slippers fit well in 41-42. This, though as a precaution already ordered in 43, is at least 1, more 2 sizes too small.
2) The shoe is not adjustable. Mich störts (I knew of course previously) in particular due to the wrong dropouts size, which thus can not be compensated.
Since the shoe seems to be of good quality, now my wife has him get, I'll look for an adjustable from Saller ...
Tip: at Saller itself partly cheaper than in Amazon Marketplace, and all sizes (with my order ie no 44).
