Our take
If you have flat feet and overpronate, the Kayano is the shoe Reddit keeps coming back to — it's the closest thing to a consensus pick in a category full of opinions.
If the Adrenaline isn't cutting it for your flat feet, step up to the Beast — it's the shoe flat-footed runners reach for when they need serious motion control, not just mild stability.
