4D Printing Helps Adidas Redefine Running Shoes’ Forward Motion

Adidas’ 4DFWD is its most advanced running shoe. It is designed to move runners in one direction only — forward. The company says it is a shoe industry first with a bowtie-shaped lattice midsole which transforms vertical pressure into a horizontal force, providing runners with a nonstop, smooth forward transition.

The company says it created this technologically advanced running shoe after it evaluated over 5 million variations of the lattice structure and combined 18 years of real-world athlete performance data to identify a design that could change the running experience. Harnessing the power of 4D, adidas collaborated Carbon to use its Digital Light Synthesis to create a precisely, fine-tuned midsole, which it says offers a scientifically proven forward motion benefit.

“When humans run, our forward motion is interrupted every time our foot hits the ground, leading to a subtle stop-start motion between strides,” says Anette (Peko) Hosoi, a Neil and Jane Pappalardo professor of mechanical engineering at the Massachusetts Institute of Technology. “This is true for all runners — no matter your ability.”

Adidas says it is always looking at the ways technology and data can intersect to create the best possible products for runners. “With the new 4DFWD, we made the impossible possible, challenging the laws of science by using a unique performance benefit designed to move you forward,” says Charlotte Heidmann, Adidas product manager. “With every stride, the midsoleof the adidas 4DFWD turns vertical impact into horizontal forward motion for an unstoppable smooth forward transition and new underfoot experience throughout the run.”

The shoe features a Continental outsole which is said to provide extra grip for running in any weather condition. It also has a Prime knit+ and engineered mesh upper construction for an extra supportive and snug fit. Complemented by an integrated heel counter, Prime knit+ is said to offer a sock-like fit while areas of engineered mesh provide support exactly where runners need it most. The 4DFWD midsole delivers 23% more cushioning than previous 4D midsole generations (4D Run 1.0), the company says.
