The Parley x Wmns UltraBoost X is crafted with a Primeknit upper which combines the use of yarn produced from Parley Ocean Plastic. This innovative material is sourced from discarded waste found on beaches and coastal areas, preventing it from polluting the ocean. Embracing a stylish two-tone blue design, this footwear is equipped with Boost cushioning, an external heel counter, and an adaptive arch. These features provide exceptional comfort and support, especially as the arch naturally adjusts to the wearer's foot over time.
