About the Nike Book 1 'What The'
Limited to just 1,996 pairs, the Nike Book 1 'What The' showcases a mixed-material build finished in mismatched colors and prints drawn from previous colorways of Devin Booker's debut signature model. Hallmark features of the left shoe include a yellow hairy suede toe box, a Safari-print forefoot overlay, and a black Swoosh surrounded by exposed stitching. The latter element is contrasted by a bright crimson textile side panel covered in a topographic map pattern. The right shoe combines a blue denim toe box with a green nubuck forefoot overlay embellished with topographic-inspired stitching. Faux snakeskin covers the midfoot panel, while the padded collar is treated to a lenticular finish in rainbow colors. A discreet tag affixed to the lateral eyestay displays the shoe's numbered edition.
