The adidas Ultra Boost has been as formidable a running selection as any in the sneaker business throughout the summer months, but now adidas is trying to ensure that you’ll rock their ever-comfortable Boost offering well into autumn. The latest colorway could just be the best yet, as a heather grey speckle lands throughout the knit upper to contrast the clean portions of white Boost on the outsole and accents on the three stripe overlay and heel cage. It’s been hard to see beyond the Yeezy Boost and Ultra Boost in terms of adidas’ success lately, as Kanye and the cushioning system have dominated headlines throughout 2015. When initially introduced, adidas dubbed the Ultra Boost the greatest running shoe they’ve ever created, and it’s not too hard to see why, especially with brilliant color selections like the one showcased in detail below.
