Really lovely boots and fits perfectly. I'm a size 5 UK but reading through the comments/reviews I would have been a 38 but went to a 40 and fits perfectly. Enough space in boot for leggings and harness if doing attack on titan cosplay.
Great boots, I normally have an european 39/40 so I decided to buy a size 42 and they fit perfectly. They are exactly as in the shown pictures. There is no zipper or anything like that, but no problem at all with getting my foot in the boot.
