The North Face Gravulus Slip-On 2 Black The following is the manufacturer's description: These outdoor slip-ons are perfect for light outdoor activities and everyday use. The upper material mainly uses durable synthetic leather. PU bonded mesh is placed on the instep to enhance breathability and fit. The highly cushioned 6mm thick punched insole also has breathability, reducing stuffiness around the feet. The highly cushioned midsole with four side walls enhances stability and supports walking. The rocker structure that generates propulsion is designed to naturally move your feet forward. The outsole, which has a wide contact surface and provides stability, uses "Surface CTRL," which provides high grip on both dry and wet surfaces. The sole's lug pattern, inspired by trekking shoes, also works on uneven terrain such as trails. 25029240
