Nike says Book is a big fan of Halloween's undead patron spirit, and the Nike Book 2 'Oogie Boogie' is built around that character. The theme runs to BOOK dice, bugs on the sockliner and an outsole that glows in the dark. Under the forefoot sits an Air Zoom unit, moved there from the heel to keep the profile low. Book's love for the Air Force 1 inspired the herringbone traction pattern, here given a modern update.
