Like last summer, adidas and Parley are bringing two different collections of ‘Parley’ shoes in contrasting colors. The duo is now expanding their partnership with yet two new unique takes on the UltraBOOST 4.0. One pair is very similar like the previous pairs, the adidas UltraBOOST comes fully construction from recycled ocean plastic materials. It features a striped Blue and Grey Primeknit upper with a Black cage and heel counter. Parley branding on the tongues and insole atop a White Boost midsole and rubber outsole completes the design. The other pair, being dubbed the ‘Deep Ocean Blue’ pair is inspired by the Mariana Trench, which is a portion of the Pacific Ocean that’s said to be the deepest part of the ocean in the world. This new colorway boasts a darker, fuller Blueish-Black than on most previous releases. The shoe’s unique Primeknit upper is offset by a Black plastic midfoot cage, and the tongue features Blue adidas and Parley branding. A White Boost midsole provides contrast and comfort, and the shoe is rounded off with the UltraBOOST’s standard Continental rubber outsole for exceptional durability. Each pair of Parley UltraBOOST prevents 11 plastic bottles from entering the ocean, so you can be comfortable both physically and mentally while wearing them-knowing that you’re doing some good.
