The Parley x Ultra Boost X was specifically designed for female runners, taking into consideration their unique requirements. This was made possible by utilizing the advanced Aramis 3D motion capture technology, which ensures a perfect fit by accommodating the shape of the foot. In addition to its functional design, the shoe is also eco-friendly. Its upper is made from Parley Ocean Plastic™, a sustainable material that is created from recycled waste retrieved from beaches and coastal communities. The stretchy carbon and Blue Sprint knit upper not only contribute to the shoe's comfortable fit but also promote environmental consciousness. To complete the shoe's sleek aesthetics, it includes a black spirit heel counter, a white Boost midsole, and a Continental rubber outsole. With its innovative features and dedication to sustainability, the Parley x Ultra Boost X is truly a remarkable choice for female runners.
