The Adidas Ultra Boost has been one of the most commercially successful sneakers of the past few years, and this spring, new versions will release for elemental trekking. As the name suggests, the Adidas Ultra Boost ATR Mid is a mid-top take on the runner, equipped with a sock-like Primeknit collar, heightened tongue and rear pull-tab. The Boost sole and cushioning is practically the same as previous models with one significant modification. Designated as ATR, the sole of the Mid-Top Boost is more rugged to combat the elements of all terrain. The Ultra Boost ATR Mid will release in "Oreo" and "Burgundy" colorways this spring.
