The Nike Book 1 'Haven' takes its name from Devin Booker's pet dog. Inspired by the Cane Corso's fur, the low-top carries a suede upper in a solid black finish. The monochrome design is disrupted by a metallic bronze Swoosh that matches Haven's eyes. Additional branding elements include 'Book' tongue tags and 'Chapter One' stamped on the heel tab, featuring a layered design modeled after a book spine. A TPU cage reinforces the lateral side of the Cushlon foam midsole, painted black and fitted with a top-loaded Zoom Air unit in the heel. A translucent herringbone-pattern rubber outsole provides grippy traction underfoot.
