adidas partnered up with frequent collaborator, fashion designer Stella McCartney, for the July 2019 release of the Stella McCartney x Wmns UltraBoost X 3D 'Leopard Print' sneaker. The shoe is created with yarn made from Parley Ocean Plastic recycled waste. The shoe includes a Primeknit 360 upper, fortified with a branded midfoot band for lockdown. The shoe's printed Boost midsole and Torsion System work together for responsiveness and stability.
