The new Adidas shoes are special to say the least. They are called 4DFWD, which is pronounced “4D forward”, which could be translated as “4D forward” in French. This new model belongs to the high-tech running division of the brand and was developed in collaboration with the company Carbon, which specializes in 3D printing. It is precisely its process that makes these shoes so strong. The 4DFWDs feature a 3D printed midsole with Carbon’s digital light synthesis technology. It is a stereolithography-based process that uses a light source to cure a liquid resin, making it possible to obtain shapes that cannot be achieved with a conventional 3D printing process. The soles produced in this way consist of a “4D grid” to support the runner and consist of 40% bio-based materials.
A structure designed to push the runner forward
According to Adidas, this structure compresses in vertical impacts and converts this force into forward motion, which saves energy while running, while reducing the required braking force by 15%. Material made from recycled polyester that hugs the foot like a sock. The shoes will be available from May 15 for 200 euros, initially exclusively via the mobile app for Creators Club members. A “Tokyo Collection” will be available from July 1st, before being released worldwide on August 12th.
