Runners with flat feet might have a difficult time finding comfortable running shoes.

If you have flat feet, you’re not alone: 27 percent of people scanned during the Fleet Feet fit id® outfitting process have flat feet. So there are plenty of other runners in the same situation.

Some runners with flat feet might benefit from a shoe with good arch support or a custom orthotic, like Superfeet, while others might like more cushioning. All of the shoes on this page are well suited to flat feet, are accommodating for a custom orthotic and provide soft cushioning.

But whatever pair you choose, the No. 1 rule of running shoes applies to the best shoes for flat feet: Your shoes should be immediately comfortable. If they’re not comfy when you first put them on and walk around, they likely only be less comfortable when you start running. So, look first for comfort.

There’s no replacement for trying on a pair of shoes for yourself, but here are the best running shoes for flat feet to get you started:

Brooks Glycerin 19

Not only is the Brooks Glycerin 19 one of the best cushioned running shoes on the market, the luxurious cushioning also earns it a spot on the list of the best running shoes for flat feet, too.

The Brooks Glycerin 19 employs Brooks’ softest foam—DNA Loft—to cushion your every step. A light, breathable mesh upper delivers a comfortable fit, and the silky fabric covering the heel cup mitigates blisters.

In the Brooks Glycerin 19 review, Fleet Feet testers say they love the soft ride and comfortable fit, making the Glycerin a plush everyday trainer that can take on a custom orthotic or insole.

Saucony Triumph 18

Not only is the Saucony Triumph 18 one of the most cushioned running shoes, it's also one of the best running shoes for flat feet.

The updated Triumph 18 has a cushy PWRRUN+ midsole that absorbs impact and bounces back quickly. The soft cushioning gives runners with flat feet an easy landing and comfortable ride.

Saucony created a snappier feel by tweaking the shape of the midsole and coating the shoe in a blown rubber outsole, while the outsole's TRIFLEX design makes for quick transitions and more natural flexibility.

Complete with a roomy toe box and secure midfoot fit, the Saucony Triumph 18 is a winner for runners with flat feet.

New Balance Fresh Foam 1080v11

Designers completely redesigned the New Balance Fresh Foam 1080v11, making it one of the best updates of the year.

With an updated Fresh Foam midsole, the 1080v11 is one of the best cushioned running shoes on the market today, which some runners with flat feet will like. Fresh Foam runs the full length of the shoe, so it gives you a smooth transition from heel to toe.

In the New Balance 1080v11 review, Fleet Feet testers said the new Fresh Foam midsole delivers a very soft and bouncy ride, and the dynamic upper gives the shoe an outstanding fit all around.

Mizuno Wave Inspire 17

Flat-footed runners who crave support can find it in the Mizuno Wave Inspire 17.

In our Mizuno Wave Inspire 17 review, Fleet Feet reviewers raved over the stable, buttery ride of the Wave Inspire 17, "The Inspire definitely feels stable, but running in it feels smooth and easy."

The Wave Inspire’s architecture includes Mizuno’s signature Wave Plate tuned specifically for stability. The Plate adds extra medial support (under the instep and arch) to level out a wobbly ride, and the firmer U4ic foam cushioning delivers a snappier step.

ASICS GT-2000 v9

Runners with flat feet can get a little extra help from the ASICS GT-2000 v9.

ASICS created extra structure in the GT-2000 v9 with its traditional stability technology. The medial post, called Dynamic DuoMax, helps reduce the effects of overpronation, while ASCIS' Trusstic system uses a plastic frame to resist twisting.

Even with the extra structure, though, the shoe never feels heavy. ASICS maintained a sub-10 oz weight for the men's model and just under 8 oz for the women's.

A FlyteFoam midsole delivers an easy ride, and a generous rubber outsole makes it grippy and durable for miles on pavement. With a spacious fit that works for lots of different foot shapes, the ASICS GT-2000 v9 is an outstanding shoe for runners with flat feet.

On Cloudswift

The first thing Fleet Feet testers noticed about the Cloudswift in the On Cloudswift review was its feeling of arch support.

“The arch support is first class,” one tester said. “And the shoe is incredibly comfortable to wear around.”

The Cloudswift is a neutral running shoe, and doesn’t have any specific medial or arch support, but the way it’s built provides noticeable support in the midfoot. Coupled with On’s CloudTec cushioning system and snappy Speedboard technology, the On Cloudswift is a nimble and supportive shoe for runners with flat feet.
