Meet the midsole that broke the mold. Since 2017, the adidas 4D has become an icon.
“With Digital Light Synthesis, we venture beyond limitations of the past, unlocking a new era in design and manufacturing.”
About this Project
adidas has provided the world’s greatest athletes with top-performing, innovative products since its inception. In 2016 adidas came to Carbon to realize completely new paradigms in their designs and manufacturing that would allow them to once again raise the bar of performance.
Rising to the Challenge
Carbon’s material scientists developed an entirely new elastomeric material, EPU 41, that could live up to the demanding mechanical properties of a revolutionary running shoe midsole. Additionally, the development of cutting-edge additive processes and tools were critical for efficiently manufacturing the new unmoldable midsole at scale.
A world-class 3D printed midsole designed by using two decades of high-speed motion capture and force data from nearly 4,000 runners. The Carbon DLS™ process allowed adidas designers to create one of the most advanced shoes with a multi-zone midsole created from a single print. The monolithic, lattice design comprises over 10,000 individual struts that enable the precise tuning of the midsole for performance––increased lattice density provides support, while decreased density creates cushioning, giving runners lasting comfort with responsive feedback.
Over 1MM 4D Midsoles Produced on Carbon’s L1 3D Printer.
Carbon DLS™ enabled adidas to rapidly iterate over 50 different lattices for the midsole before landing on the current design.
Carbon developed a full print and post-processing method for the new 4D midsole, ensuring that the end result was the best combination material and print process for adidas’s design.
The Carbon DLS™ process enabled adidas to expand its product portfolio rapidly, responding to market demands and customer desires faster than ever before.
