Our Verdict
Diadora Nucleo 2
Saucony Ride 19
The Saucony Ride 19 is a much better running shoe than the Diadora Nucleo 2. It's lighter, far more energetic, and better cushioned for daily training and long runs, while still being impressively stable. Get the Diadora if you prefer its styling or want the more stable ride; otherwise, the Ride 19 offers much better running performance for less.
