Super comfortable and adorable! It was a gift for my mother who loves them! Good quality and fast delivery. The 41 (it's 40/41 on the shoes) corresponds to a 39/40 French. It's my mother's size and they fit her perfectly. I do 38/39 (I'm also between two sizes), they go level length but are a little too wide and so do not hold very well to the feet, but I have particularly thin feet. If you make my size with a wider foot I think it should go. I recommend these slippers. (39/40 French = 38/39 European)
Good sneakers, but ordered for size more than on the grid, with pink on the seller's grid 40-41, my size is 39-40. Blue on the seller's grid 42-43, the size 41 is slightly too small because of the projection from behind. In general, I recommend!
