First it was Xeno, and now adidas Originals introduces another unique color-shifting treatment, Chromatech. Here’s how it works, straight from the brand: “As the Chromatech material expands and contracts the color responds and changes. The natural color shift creates a color spectrum unique to how each shoe is worn, so that no two pairs are alike.” Chromatech debuts on the stylish SL Loop Racer, the new streamlined edition of the popular SL Loop, in three colorways, including gold, black, and purple, each with their own unique pattern of Chromatech coating. The adidas Originals SL Loop Chromatech officially launches May 8th at select retailers and adidas.com/originals.
