The Adidas Ultra Boost ATR Mid 'Grey' is a mid-top version of the popular Ultra Boost runner designed for all-terrain use. This particular colorway showcases a combination of different shades of grey on its Primeknit upper, as well as a higher tongue and embossed 3-Stripes side branding. The shoe also features a dark grey textured heel counter, which displays silver ultra boost branding, and a clean white Boost midsole. To ensure excellent grip and durability in adverse conditions, a rugged all-terrain black Continental rubber outsole is incorporated. The 'Grey' variant was released as part of a three-pack, alongside the 'Oreo' and 'Burgundy' colorways.
