I can't guarantee they are original. They look like they went under some kind of DIY repairment, so it is even harder to say. I can say label is sewen and not glued, but in one shoe it kind of changed its form (it looks like it happened from use). Sole definitely looks handmade,but not very precise - but I was seeing designer stuff from early 80s and earlier not being very precise. See photos for details.
insole: 26,5cm (including pointy part)
