With Adidas renewing attention on single-piece 3D-printed sneakers with its new Climacool shoes, home-printing options are expanding rapidly, too.

Recreus' footwear-focused Filaflex filaments have recently been updated to introduce subtle new colors through a collaboration with Footwearology – a design lab and educational resource for shoe fabrication. Besides their regular colors, the company's Filaflex Foamy, Foamy 95, and 82A filaments are now available in Oat (pictured), Lavender, Mint, Azure, and Dusk hues.
