The Saucony Grid 8500 seamlessly combines the upper of the Grid 9000 with the midsole and outsole of the Grid 8000 CL. The running shoe has a neutral characteristic with a light grey top and creamy-white bottom. The foot slides easily into the neoprene sockliner, which is supported by leather and suede overlays. The Saucony Grid 8500 features Saucony's landmark G.R.I.D. midsole cushioning system, which stands for Ground Reaction Inertia Device.
