About the Nike Book 2 'Spiridon'

The Nike Book 2 'Spiridon' showcases a familiar design that channels a classic OG colorway of the Air Zoom Spiridon. Laces feed through webbing eyelets to secure the upper, crafted from silver open-cell mesh with a durable black synthetic mudguard. Outlined in black embroidery, a shiny red Swoosh adorns the quarter panel. Anchoring the sneaker is a lightweight Cushlon 3.0 midsole with a springy Zoom Air unit in the forefoot.
