New Balance calls it “the first high performance running shoe with a 3D-printed midsole”.
We are all for high performance running shoes.
Sean Murphy, New Balance Senior Manager of Innovation and Engineering, says:
This project represents an unprecedented technical collaboration in footwear.
He goes on to say:
To deliver this level of performance with a 3D-printed component, we paired experts in running and biomechanics with leaders in plastics engineering, material development and generative design. These are the types of collaborations that will drive footwear design and manufacturing in the future.
According to New Balance:
The latest designs of the 3D-printed midsole are based on underfoot pressure data from heel strikers with more cushioning elements in areas of higher average pressure. This data to design formula follows the path that our designers used to create the award-winning Fresh Foam collection. For midsole production, we use selective laser sintering (SLS), a process which converts new powder materials into solid cross-sections, layer by layer, using a laser. DuraForm® Flex TPU powder gives the resulting parts a previously unavailable combination of strength and elasticity that is ideal for performance running shoes.
