Adidas is back with another sneaker based on a 3D-printed midsole, but this time the company says it's moving even closer to mass production. The Futurecraft 4D shoe will be the first one using Carbon's "Digital Light Synthesis" process. The Silicon Valley company's tech creates 3D items by blasting liquid with light, which Adidas says will allow it to operate on "a completely different manufacturing scale." The shoes themselves have a slightly different midsole than their predecessors too, matching last week's leaked model with a midsole that protrudes horizontally, increasing the visual 3D effect.
