The Parley x adidas adizero Prime Boost comes constructed out of a lightweight and breathable Primeknit upper in blue that is made of 95 percent Parley ocean plastic. Other details include a full-length Boost midsole in white, Torsion System, a bar made from renewable materials that supports the foot’s natural flex from heel to toe, and a Continental natural rubber Stretchweb outsole that injects underfoot flex and energy and also provides all-weather traction.
