The Parley x adidas UltraBoost Uncaged is a stylish and sustainable sneaker that emphasizes a simplified design, drawing inspiration from runners who have modified their shoes by removing the cages. This eco-friendly shoe was introduced in June 2018 and features a melange Primeknit bootie crafted from recycled waste materials. Additionally, it offers internal reinforcements and a Fitcounter heel for a supportive and comfortable fit. The shoe also incorporates a flexible Stretchweb outsole with Continental rubber, enhancing responsiveness and durability through the Boost technology.
