Stability and motion control.
For flat feet, choose a stability shoe rather than a neutral one. Stability shoes use structural features such as guide rails or a medial post to limit how far the foot rolls inward, whereas neutral shoes only cushion. Maximum-cushion neutral shoes often make it worse.

When you walk, your foot rolls slightly inward as it lands. That is normal. If it rolls inward too much — overpronation — the arch collapses and strain travels up through the arch, shin and knee.
A stability shoe is built to limit that motion. A neutral shoe is not; it only cushions. Getting this wrong is why expensive shoes sometimes feel worse than cheap ones.
Stability shoes aren't all the same. Modern guided designs and traditional medial posts solve the same problem in very different ways.
The question isn't which is most cushioned. It's whether you need a stability shoe or a neutral one — and most people don't know which they are.

Check the wear pattern on an old pair. Heavier wear along the inner edge of the sole suggests the foot is rolling inward. A gait assessment at a running shop or podiatrist is more reliable than guessing.
Often, yes. A very soft neutral midsole gives the foot more room to roll inward rather than less, so structure matters more than softness here.
