The next big thing in the world of shoes might not come from an overseas factory but from a printer. A 3D printer, that is. Designer and engineer Luc Fusaro is working on creating a pair of shoes that can be manufactured from the comfort of a 3D printer. What’s special about his is the inclusion of spikes, which make for a more athletic appeal and distinguish them from the existing slate of 3D-printed shoes. The other unique thing is that Fusaro’s plan is to design shoes that fit specifically to the size and shape of the owner’s feet. After scanning their feet, Fusaro will be able to custom-print a pair of shoes that could shave off a few seconds of time from a professional runner’s lap.
