THE SHORT ANSWER
Drop is the real difference: 6 mm on the Adizero Boston 13 against 8 mm on the Novablast 6. Coming off the Novablast 6, the Adizero Boston 13 loads your calves and Achilles harder for the first couple of weeks. They are built for different jobs: the Adizero Boston 13 is a tempo, the Novablast 6 a daily trainer. The Novablast 6 lists $5 lower.
