Finding the right running shoes can help runners with flat feet enjoy smoother, more comfortable runs, especially if they experience overpronation or fatigue during high-impact workouts.
That is where supportive running shoes come in. With their Swiss-engineered designs and signature CloudTec® soles, On running shoes combine cushioning, stability and modern style. Here is your guide to the best On running shoes for flat feet.
What Should You Look for in Running Shoes for Flat Feet?
Flat-footed runners do not all need the same type of shoe. When choosing your next pair, look for:
- A stable, wider base for a more balanced landing
- Comfortable cushioning for daily training and longer distances
- A secure heel counter to help keep your foot in place
- Enough room in the toe box for natural movement
- Supportive features that guide your stride without feeling stiff
- A fit that feels comfortable from the first try
If you regularly experience foot, ankle, knee or leg pain, consider getting a professional gait assessment.
Best On Running Shoes for Flat Feet and Overpronation
1. On Cloudrunner 3: Best Overall for Everyday Runs
The On Cloudrunner 3 is a strong everyday option for runners with flat feet who want a balance of cushioning and stability. Its wide CloudTec® platform, Helion™ foam, higher sidewalls and asymmetrical heel clip help create a more controlled and supportive ride for daily runs, treadmill sessions and walks.
2. On Cloudrunner 3 Wide: Best for Wider Feet
The On Cloudrunner 3 Wide offers the same stable design as the standard version but with a roomier fit. It may suit runners with wider feet, low arches or feet that swell during longer runs. The extra space allows your feet to sit more naturally on the platform without feeling squeezed across the midfoot. When choosing your size, ensure that your toes can move comfortably while your heel remains securely in place.
3. On Cloudrunner 3 Max: Best for Maximum Cushioning
The On Cloudrunner 3 Max is designed for everyday and long-distance runs, combining maximum cushioning with a high level of stability. It is a suitable choice for runners who prefer a softer, more protective feel underfoot, particularly during longer sessions or runs on hard surfaces.
4. On Cloudflyer 5: Best for Extra Support
The On Cloudflyer 5 is worth considering if you prefer a more structured and supportive running shoe. It features a wide platform, dual-density Helion™ foam, a molded heel counter and a padded ankle collar for a stable, cushioned ride. These features can help runners who want additional guidance and support during daily training or longer runs.
5. On Cloudmonster 3: Best for Responsive Cushioning
The On Cloudmonster 3 is a good option for runners with flat feet who prefer a more energetic and responsive ride. Its triple-layer CloudTec® cushioning, Helion™ foam, Speedboard® and rocker shape help create a smooth, forward-rolling feel for everyday and long runs. However, it is classified as a neutral-support shoe, so it may not provide enough guidance for runners with significant overpronation.
Are On Cloud Shoes Good for Flat Feet?
Yes, On Cloud shoes can be good for flat feet, but not every On model is designed for the same type of runner. On offers neutral, cushioned and stability-focused shoes, so the right model depends on how your foot moves when you walk or run.
For runners with flat feet and overpronation, the Cloudrunner and Cloudflyer collections are the most relevant places to start. For runners with flat feet but a neutral gait, other On models may feel more comfortable. A proper fitting assessment can also help you choose the right level of support for your stride.
How to Make Sure Your On Running Shoes Fit Properly
Even the best running shoes will feel uncomfortable if the fit is wrong. When trying on your On shoes:
- Try them on with the socks you usually wear for running.
- Leave a little space in front of your longest toe.
- Make sure your heel feels secure without pressure.
- Walk, jog or test them on a treadmill if possible.
- Check that your arch feels supported, not pushed aggressively.
- Try shoes later in the day, when your feet may be slightly more swollen.
Your feet can swell during a run, so a little extra toe-room is helpful. However, the shoe should still feel locked in around the heel and midfoot.
The best running shoes for flat feet should help you feel supported, comfortable and confident. Most importantly, do not choose a pair based on hype alone. Try them on, pay attention to how your feet move and pick the pair that makes you want to run that extra mile.
