The sole has been redesigned to the millimetre to provide softer cushioning and prevent overpronation. The upper of this shoe is made with a high-performance yarn that contains at least 50% Parley Ocean Plastic, a recycled plastic waste in order to prevent pollution of our oceans. The other 50% of the thread is recycled polyester.
