what do you guys think about running in nike shox. when i had a pair I found they were too heavy and I couldn't run with any speed. They are no good at the gym either, try doing free weight squats with heels elevated that much. Adidas megabounce and microbounce are the best track shoes I ever wore. they are very light when running sprints. i can get on my toes very easily and run like a gazelle.
