A prototype after a prototype. Innovation after innovation. Endless testing.

This model is equipped with functional recycled Primeblue material made from Parley Ocean Plastic. 50% of the upper is made from textile, and 75% of that textile is made from the Primeblue materials. No more new polyester.
