Our Verdict

Diadora Nucleo 2

Diadora Corsa

The Diadora Corsa is a better daily trainer than the Diadora Nucleo 2. It's significantly lighter, offers more impact protection, and is far more capable across paces and distances than the Nucleo 2. Even though the Corsa is less stable, it's still a secure shoe, and the Nucleo 2 really only makes sense if you want to sacrifice performance for even more support.
