As reported on footwear trendspotting site Sole Retriever, Nike appears to have accidentally posted a new purple color Air Max 1000 on Zellerfeld, before taking them down again. Thought to release later this year, they'd join black as the second color of the high-profile 3D printed footwear release. Also on Sole Retriever, there's an update on Adidas' Climacool fully 3D printed slip-on sneakers, which are coming soon in a cool Grey Four variant in grey with contrasting black Adidas stripes.
