Designed for future runners and marathon runners, the all-new Clifton 9 Youth offers revolutionary performance despite its small size. With the idea of emphasizing sustainability we chose an ultra-light 30% sugar cane midsole, 31% rPET yarns obtained with less water to reduce emissions, and anti-abrasion rubber in the points most subject to wear for superior longevity. The result? A futuristic model, created with the new generation in mind.
