A beautiful shoe, unfortunately it is very small. I wear size. 40 and have also in Gr. 40 ordered. The actual size is, in my opinion, about a half to one size smaller. In addition, the shaft is very narrow cut, making it suitable only for very narrow shackles. A great pity, because visually the slip boots is absolutely top. The build quality is great, only the zipper on the heel stuck on both shoes. Due to the size I have returned the shoes.
