100% leather overlays. Mesh Uppers. EVA midsole. Rubber outsole. Cushioned inners. True sizing. The Shadow 6000 from Saucony were first invented for track-traversing athletes back in the 90’s, and have since evolved to be popular amongst both cardio-dodgers and sports-enthusiasts alike. Those cushioned liners are there if you could use a sneaker-induced spring in your step, and are assisted by the supreme flexibility of those comfy mesh upper. The sci-fi slithers of silver transport us right back to a pre-millenia state of mind too.
