On rare occasions, sometimes when you least expect, the desert night will come to life with awe-inspiring Aurora Borealis as far south as Arizona. The uncommon occurrence brings a new level of spectacular to the skies—and this special Book 1. The upper is fully made of a reflective-backed mesh. The lenticular Swoosh logo and collar colour shift with movement. And, a glow-in-the-dark outsole adds a galactic touch to this high heat wonder. Stop and go A top-loaded Zoom Air unit in the heel provides a measure of responsive speed when taking off in the open floor and coming to sudden halts, like a 2-footed Book jump stop and pump fake around the rim. Plant and pivot A top-loaded midfoot strong plastic plate helps keep your foot stable when making sudden movements like sharp plants, Book-like pivots and jabs in the post and opportunistic cuts. A strong plastic sidewall cage adds even more stability. Cut hard The multi-directional, herringbone-like pattern gives you sticky traction that's ideal for lateral cuts and quick changes in movement. Full-go foam The soft, responsive full-length foam can help you keep running and cutting in comfort.
