These are likely suede Sportiva boots from the 70s or 80s. They may be the Super Winkler model, but it's uncertain. I believe this is a rather rare item, so it would be a good addition to a collection. Size: EU 41 Listed as 26 cm, but they fit small, so I think they're closer to 24-24.5 cm. There is some soiling, but the soles have hardly worn down, and they are in good condition for their age.
