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.
Brooks Adrenaline is the default recommendation for flat feet for a reason — it's forgiving, well-cushioned, and the GuideRails system does real work. Just know that some runners find it breaks down faster than expected past mile 2.
