Vintage Aigner leather flats with jute soles bamboo accents 8 1/2

Etienne Aigner deep rust color almost burgundy but not flats with jute detailing and jute soles bamboo/wood accents give these flats a definite Gucci like feel. In excellent condition. Cannot find size on them so please see pics with measurements. I think size is covered by heel cushions that were placed in both shoes. I compared to 8 1/2 shoes I have and they are the same length. I think these are vintage but I’m not certain. These shoes are gorgeous!! Please view all pics and thank you for looking!
