Whether on the trail or in the city, the XT-4 OG by Salomon is a high-performance trail running shoe that combines quite a few features. The upper is made of a breathable ripstop fabric with a strong and durable mesh lining. The Mud Contagrip sole, with its grip-focused material compound and deep, sharp lug design, gives excellent traction and grip, while the EnergyCell midsole and Agile Chassis Skeleton provide cushioning and a responsive and energetic feel.
