The VJ Sarva Ace for men is the most cushioned and comfortable starstudded VJ winter running shoe yet. The Ace is also the first winter running shoe that features the PerFOAMance midsole, which offers more comfort and cushioning than the previous EVA midsoles, making winter runs on ice and packed snow easier for your feet. The Superior Contact -outsole features 17 carbon steel, star-shaped metal studs that provide superior grip on slippery conditions. The Aces upper is waterproof and durable one-piece upper. Adding to the comfort and fit, the shoe is foot-shaped, has a roomy toebox and has a soft heel that prevents the foot from chafing. The innovative Fitlock-system offers an optimal fit for the shoe by locking the foot from the arch. It also offers extra protection by protecting the arch from the impacts the foot is facing while running. Technical Features Midsole Stack: 25mm/17mm Midsole: PerFOAMance Outsole: Superior Contact + 17 carbon steel studs Upper: Waterproof, one-piece Lug
