New Balance will soon be offering a choice of standard or custom insoles for sneakers sold in North America and parts of Asia. The custom soles will be supplied by Superfeet and its collaborator on this venture, the 3D printing arm of HP. The Fitstation by HP + Volumental, a 3D scanner and gait analyzer, will feed specifications from scans of customer feet into an HP Jet Fusion printer to produce 3D-printed-caps for assembly at the Flowbuilt Manufacturing plant in Ferndale, Washington.
