The Nike SB Zoom Blazer Mid Premium is a celebration of Sashiko—the Japanese technique of decorative reinforcement stitching. Premium Patchwork Sashiko is a form of decorative reinforcement stitching that originated in Japan. The technique was used to create new items out of old, worn ones. Responsive Performance Foam sockliner with a Zoom Air unit in the heel delivers plush cushioning. Flexible Grip Vulcanised construction fuses the outsole to the upper for a flexible, broken-in feel.
