The quality and workmanship of the Adelheid-slippers is very good, recommended the article basically! Only one should note a number greater to choose when buying. The donee person wears size 41, but the double size 40/41 was too small. However, trouble-free conversion and 42/43 fits comfortably. I myself have bought a different model, usually wear 39, and here so watch the 40/41 ... not an isolated case ;-)
