THE SHORT ANSWER
Drop is the real difference: 8 mm on the Endorphin Speed 6 against 10 mm on the Pegasus 42. Coming off the Pegasus 42, the Endorphin Speed 6 loads your calves and Achilles harder for the first couple of weeks. They are built for different jobs: the Pegasus 42 is a daily trainer, the Endorphin Speed 6 a tempo. The Pegasus 42 lists $30 lower.
