Since launching her eponymous brand, Stella McCartney has made it her mission to campaign for animal rights.
Upon establishing her namesake brand, McCartney endeavoured to make hers an ethical and conscious company, which vowed to never use leather, fur, skins or feather in the production of any of its materials.
And while some thought at the time that she'd never be able to make green en vogue, it would appear she's proved the naysayers wrong.
For she has just designed - due to high demand - her second vegan iteration of the iconic Adidas Stan Smith trainer.
And these are some seriously fun trainers that guarantee twinkle toe-status.
Not only are the sneakers leather-free and made using completely vegan materials, the classic Adidas three-stripe pattern on the side of the trainer has also been replaced with punched out, laser-cut stars in rainbow shades.
In addition to the trainer's homage to tennis player Stan Smith - his face remains printed on the tongue of the right shoe - 48-year-old McCartney's portrait and signature now takes pride of place on the left-hand side of the shoe.
London-born McCartney launched her first sustainable take on the iconic Adidas shoe in 2018 to critical acclaim and it instantly made history as the world’s first vegan-friendly line of Stan Smith trainers (the Duchess of Sussex was a big fan.)
Given that the global footwear market is expected to grow to $426 billion by 2022, and the production of one pair of running shoes emits 13kg of carbon dioxide, McCartney's sustainable footwear collaboration is most-welcomed.
McCartney has been collaborating with Adidas since 2005, launching an array of athletic-wear, eyewear, swimwear, fragrances, and lingerie in partnership with the leading sportswear brand, and most recently a post-masectomy sports bra.
Each pair retails for £235 and will be available to buy from December 2. You can sign up here.
