One of the best high-mileage running shoes from 1991, the iconic Saucony Shadow 6000 you see today is a lifestyle sneaker with seriously high-function roots. The Shadow 6000 looks great as a casual shoe but can still be used to break a sweat thanks to its premium sock liner, ionic cushioning system, and EVA midsole that make sure it still represents Saucony’s best over three decades later.
