All-new ReactX foam midsole is 13% more responsive than previous React technology. * Crafted for performance and planet, ReactX foam is engineered to reduce its carbon footprint by at least 43% in a pair of midsoles due to reduced manufacturing process energy compared to prior React foam. The carbon footprint of ReactX is based on cradle-to-gate assessment reviewed by PRé Sustainability B.V and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered.
