Nike SB PS8 Men's Shoes 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. An updated Flyplate is integrated into the sole, providing a responsive feel that works in tandem with the HART (High Abrasion Rubber Tech) outsole. HART uses less rubber to helps make the outsole lighter and more flexible. The PS8 wraps it all in a low-top silhouette with Nike Running aesthetics, heritage pattern and all the technical details that matter. HART outsole uses less rubber compound than our other XDR rubber technologies—without sacrificing durability and abrasion resistance. Updated Flyplate creates longevity in the foam and performs like it's fresh out of the box. Snappy and responsive, Air Zoom cushioning helps provide a quick-off-the-ground sensation.
