Introduced in 1985, the Saucony Shadow was originally a performance trainer. It's now more of a lifestyle shoe, but with the same comfort and stability that made it suitable for activity in decades past. The upper combines mesh and nylon with suede overlays for durability. Inside, there's a fabric lining and an EVA sockliner, which combines with the EVA midsole for comfort. A TPU heel piece adds support, while a triangular tread pattern on the rubber outsole provides traction.
