In November, the Alphaedge 4D, engineered with the adidas 4D midsole for controlled energy return and breathable cushioning during intensive training runs, becomes available in larger quantities for the first time worldwide. The midsole of the silhouette started out as a conceptual Futurecraft innovation, which had not only allowed adidas to completely re-think manufacturing processes, but to create a data-driven experience that breaks new ground in performance capability and comfort. The adidas 4D midsole is printed with light and oxygen, using Digital Light Synthesis. This technology, pioneered by Carbon, uses digital light projection, oxygen-permeable optics and programmable liquid resins to print high-performance, durable polymeric products.
