The veggie fashionista created her first pair in 2018. Now she has updated the design with some colorful tweaks.
The white laces have been replaced with a rainbow-colored alternative, and the three lines of stars down the side are in multicolored hues.
Saving animals lives
"Consumers really are more conscious of where things come from now, and how they are made," McCartney told British Vogue.
"But I think many people don't really care or can't tell the difference between the real leather and faux leather pair. It just makes me think how many animals' lives could be saved if Stan Smith and Adidas would change from real leather to vegetarian leather, and use non-animal-based glues like we use."
"The launch of our vegan Stan Smith brought us a whole new customer which was predominantly the younger generation. So many young people came into our stores to enquire about the Stan Smith, asking questions about what the trainer was made with, telling our staff about why it was important for them to choose a vegan shoe over a leather one and what it represented. This is the future."
The trainers, which retail for £235, launch on December 2.
