adidas Adizero Evo SL vs R.A.D UFO

The R.A.D UFO and adidas Adizero Evo SL are both marketed as versatile trainers, but what does that translate to in practice? The adidas Adizero Evo SL leans into pure responsiveness, using a partial plastic shank paired with Lightstrike Pro to create a stiff, propulsive feel that's best when you're running steady to fast, but it can feel a bit firm on true recovery days. The R.A.D UFO takes the versatility angle through cushioning, staying fully unplated and offering a more forgiving, comfort-forward ride that's easier to settle into for long runs and easy mileage alike. Despite its higher stack, the R.A.D feels more laterally stable thanks to its broader platform, while the adidas feels more nimble and workout-ready when you want a crisp toe-off.
