Yes I believe those are vintage. Those specific shoes have a very '70s style to them IMO! Probably this maker is not in business any more? That would explain why you're only seeing them on the secondary market (eBay and other sites).
Devik, oh thank you so much for ur reply. my customer was looking for this shoes, she has really narrow feet and she fits this brand AAAA width shoes. it is kind hard to find AAAA width shoes in the city and I wanted to help her.
