Our Verdict

ASICS GEL-NIMBUS 28

ASICS GT-2000 15

The ASICS GT-2000 15 and ASICS GEL-NIMBUS 28 are two daily trainers by the same Japanese brand, but only the GT-2000 includes dedicated guidance for overpronation. It's also much lighter and more energetic. The NIMBUS provides substantially deeper cushioning that stays more protective over long distances, making it the better option for neutral runners who don't need extra guidance and those prioritizing recovery and long runs.
