Court command and forefoot quickness let you play at your own Book-like pace. Through thick and thin, Book's stayed 10 toes down in the Valley of the Sun. He's Michigan tough and Mississippi mannered, but the all-time Sun might as well be the state's native son. This Book 2 takes its cues from that basketball-crazed city and culture. Iconic vibrant purple and oranges represent Phoenix's rich hoop history and Book's commitment to the franchise. Speed Control We moved the Air Zoom unit from the heel to the forefoot to provide an extra turbo boost so you can blast past your defender. Quick on the Ball An updated midfoot webbing system works with a moulded upper to provide extra stability for jabs and pivots. Play with Tempo A lighter upper compared to the Book 1 and a lower-to-the-court feel help you stay steady and balanced for hesitations and step back jumpers.
