Designed to put in the work out of the box, the PS8 delivers with a 3-pronged approach. Starting with a layered Flyknit construction with leather in high-wear areas, it offers a broken-in feel that retains its shape session after session. Air Zoom cushioning in the heel combines with an integrated Flyplate to provide a responsive feel that works in tandem with a rubber HART outsole that resists wearing down. Breathable, durable and comfortable, the PS8 wraps it all in a low-top silhouette with Nike Running aesthetics, heritage pattern and all the technical details that matter. Benefits - Air Zoom cushioning provides a snappy, responsive feel underfoot. Product Details - Leather upper. Foam midsole. Rubber outsole.
