adidas is growing its Ultra BOOST lineup with the launch of the Ultra BOOST ATR Mid, an all-terrain version of the brand's popular running shoe. The model keeps the core design of the original -- including the white BOOST midsole and a reinforced heel counter -- while adding a heightened sock-like collar and a high-traction rubber outsole. Rope laces and molded three-stripe detailing on the quarter panels finish the look. The new silhouette is set to launch in the coming weeks in this heathered burgundy colorway. Check out detailed images in the gallery below, and stay tuned for word on the confirmed release date.
