Today Adidas by Stella McCartney launches the Parley UltraBOOST X, a shoe designed to enhance every run – and make a difference to the planet.

Underlining the brand’s commitment to eco-innovation, the Parley UltraBOOST X was created as part of Adidas' partnership with Parley for the Oceans, which sees marine plastic waste transformed into performance yarn. Inspired by the boundless energy of the oceans’ open waters, the shoe design combines Stella McCartney’s sustainable approach to fashion with Adidas innovative use of technology.

Cyrill Gutsch, founder of Parley for The Oceans: "Stella McCartney is a pioneer, a rebel really. Her vision to create fashion without using leather, without using fur was radical when she started and is proven now. She has always been a role model for me. To partner with her is an honour and a huge opportunity for the Ocean Plastic movement. Adidas has been family to Parley since the beginning and is driving and implementing the Parley AIR Strategy​ in the most ambitious and efficient way. Both of them are strong agents of change who help us shape a new reality, one that allows the oceans and mankind to co-exist in peace, in collaboration even."

“I strongly believe in making clothing that is ethically created and built to last, and this is an ideology I channel into every single piece I design. For me, preserving and respecting the planet is fundamental to what I do and I always try to make an effort to consider that in my designs. I’m really impressed by the work Adidas and Parley for the Oceans do to create the materials used in our high-performance apparel and footwear,” says Stella McCartney.

Innovative and eco-friendly, the Parley UltraBOOST X features high-performance Parley Ocean Plastic yarn knitted into the Primeknit upper. Crafted to reflect the female foot’s natural form, the shoe provides the perfect, sock-like fit, delivering more stability than ever before. Designed with an innovative lacing system that supports quick-fire movements, the sleek, effortlessly stylish white palette echoes the modern design cues for which Stella McCartney is known.
