Glerups Felted Wool Leather Sole Slippers 40

Size 40 “US Size 10” EUC Gently worn a handful of times. Unfortunately as the soles are leather, they discoloured very quickly, but there is no sign of real wear. I have worn around the house maybe 30 days. Finally I find these are too snug for me and I should have sized up, so deciding to sell!
