The Nike Book 1 EP Mirage (Sail Outsole) is part of NBA player Devin Booker’s first collaboration with Nike. The "EP" in the name stands for "Engineered Performance," which means the sneaker was designed with performance and durability in mind. The upper is made of leather in Light Orewood Brown and woven textile panels in a similar off-white color. The leather overlays cross the heel and forefoot areas without forming a lace cage. Swoosh logos in tonal Light Orewood Brown check across the side panels and are outlined in off-white stitching. In terms of technology, the midsole boasts a Zoom air unit and Cushion 2.0 Foam, while TPU sidewalls reinforce the shoe. Our StockX experts like the use of micro-perforated suede on the heel collar. It gives the sneaker subtle texture and makes the slightly warmer tone on the collar stand out. The Nike Book 1 EP Mirage (Sail Outsole) was released on February 17th, 2024, and retailed at $140.
