To mark the start of the IAAF World Championships today, Adidas has revealed adizero Prime Parley, a fast-focused, elite running shoe with the same engine and construction as adidas’ marathon world-record setting models.

The latest creation in the adizero collection fuses high performance, innovation and style with purpose, thanks to the integration of Parley Ocean PlasticTM which is made from upcycled waste, intercepted before it reaches the ocean from beaches and coastal communities.

Per Adidas,

"The adizero Prime Parley, available in colorways inspired by the oceans and combined with the colours of the IAAF World Championships, is the latest product launch in the ongoing partnership between adidas and Parley, a charity committed to the conservation of the oceans. Each Energy-return BOOST™ midsole with Primeknit upper prevents approx. 11 plastic bottles potentially from entering our oceans."

The adizero Prime Parley is available for $200 in limited numbers in the U.S. on August 8th at adidas.com.
