Best Running Shoes for Flat Feet
We put this question to ChatGPT, Claude, Gemini and Perplexity every week — then check their pick against the people who actually used it.
Power ranking
The top products right now.
This week?
The 860v13 fell hard this week, dropping from third to twenty-fourth in the flat-foot running shoe rankings. Asics made two moves up the list: the Gel-Kayano 32 climbed thirteen spots to land at five, while the newer Gel-Kayano 30 held the top slot. Two fresh entries reshaped the middle tier—the Guide 17 debuted at two and the Adrenaline GTS 24 arrived at four—suggesting AI raters are shifting toward newer models and away from older stock across the board.
What AI values here
AI consensus prioritizes stability above all—shoes rated highly combine arch support and motion control to keep your feet aligned during runs rather than rolling inward. Cushioning comes second, balancing shock absorption with a lightweight feel for sustained comfort.

What the machines think.
Three AI models read the category and rank every product. They agree on the very top — and split harder than anywhere else below it.
Model by model?
How each AI ranked it.
All three models open with the same #1 when they agree — below it their lists diverge. Each column is one model's own ranked picks; the lead pick sits a touch larger, and a lone tag marks a product only one model chose. The board below merges them into one machines-only top 10.

What reviewers say about Gel-Kayano 30 for this question
Reviewers confirm the shoe delivers the stability and arch support that flat-footed runners need without the rigid feel that can cause discomfort.
- Stability support feels natural and understated rather than forceful, so the shoe works well for flat feet without feeling restrictive
- Wider platform and spacious toe box accommodate foot swell and provide room for orthotic inserts that flat-footed runners often need
- Soft midsole cushioning with good stack height supports the arch without feeling unstable or collapsing underfoot

Before you buy
Questions buyers ask.
What type of running shoe is best for flat feet?
Stability shoes are the primary choice for flat feet. The top picks combine stability support with responsive or cushioned midsoles to balance support and comfort during running.
Does the Gel-Kayano 30 work well for flat feet?
Yes. Reviewers say the Gel-Kayano 30 delivers subtle, centered stability that does not feel rigid, and its wider platform and roomy toe box accommodate foot swell. It suits runners seeking daily-trainer comfort with stable support.
What are the downsides of the Gel-Kayano 30?
The upper runs hot and lacks breathability in warm conditions. It is heavy for a daily trainer, and some reviewers noted a slappy sensation underfoot when heel striking, especially when new or fatigued.
Who should not wear the Gel-Kayano 30?
It is not suited for runners chasing speed work or maximum energy return, those needing a lightweight trainer, or anyone whose feet run very hot in plush uppers.
Are Brooks shoes good for flat feet?
The Adrenaline GTS 24 from Brooks is ranked among the top picks for flat feet and offers motion control and structured support.
What should I prioritize when choosing a running shoe for flat feet?
Stability is the primary consideration for flat feet. Responsive or adequate cushioning is secondary, to balance support with comfort during running.
Do the AI assistants agree on the top pick?
Not quite — they split across 4 different picks. Claude leads with Brooks Adrenaline GTS 24; ChatGPT leads with ASICS Gel-Kayano 32; Gemini leads with Brooks Adrenaline GTS 23; and Perplexity leads with Brooks Adrenaline GTS 25.
If the pick isn't right for you?

Beyond this question
Where the winner shows up elsewhere.
context & history
Flat feet change how your foot lands. The arch does not rise. Your shoe must support this. You want control without stiffness. Most runners with flat feet need a shoe that guides the foot inward. This costs money. Cushioning alone will not fix the problem.
The shoe companies know this. New Balance built the 860 series for stability. Brooks made the Beast for severe overpronation. Asics offers the Kayano with its support frame. These shoes have sold for years. You will find strong opinions on each one. The choice comes down to how much control you need and what your foot tolerates. Run in them before you buy.
