The adidas AlphaEDGE 4D LTD is the product of adidas’ partnership with CARBON, an authoritative force in both design and technology. Together with CARBON—and the firm’s Digital Light Synthesis technology—adidas uniquely crafts the midsole of each 4D shoe, harnessing light and oxygen to pioneering results. Using this breakthrough technique, adidas is able to create midsoles that are specifically tuned to provide superior, controlled energy return. In addition to the 4D printed midsole, the AlphaEDGE 4D LTD comes with a lightweight mesh upper.
