People with flat feet have a shallow arch or no arch, sometimes leading to foot, knee, leg, and back pain. Since the body compensates for a lack of stability, it complicates occasional pain by turning it into chronic muscle strain. While some people choose surgery, external interventions—like the right pair of insoles—can alleviate issues that come from flat feet. 

There is no specific category of insoles for over supination, but looking for flexible materials is a good place to start. “There’s a stronger material that resists friction,” says John Huenink, Founder of custom insole company BioMoto. He notes that finding an insole with a metatarsal pad may help correct the issue of flat feet. 

In addition to pain relief, insoles can make your shoes more comfortable and supportive. But before choosing a pair, consider the cushioning in the insole and what shoe types you’ll be wearing.

Here are the best insoles for flat feet, according to a certified running coach.

What to Look for in an Insole for Flat Feet

Shoe Type

A huge factor in choosing your insoles is the shoes you’re planning to use them in. If you’re wearing them in walking or running shoes, you’ll most likely be able to remove the existing insole and replace it, so the thickness of the insole won’t be an issue. However, if you’re wearing dress shoes or low-profile ones, you should probably avoid more cushioned, thicker insoles.

Support

People with flat feet or those prone to foot issues such as plantar fasciitis need firm arch support. The severity of your flat feet should determine the level of support you need. If you have totally collapsed arches, you might need more corrective arch support, while those with a slight arch could use low-profile support.

Cushioning

Insoles for flat feet should have ample cushioning for shock absorption and comfort, but also enhance the overall support. If you experience shin splints or walk primarily on pavement, you may need some more cushioning.

FAQs

Do insoles help flat feet?

A good pair of insoles can support or raise the arch, giving people with flat feet relief from muscle strain and other foot pain. “Inserts can be beneficial to people with flat feet because the inserts can limit excessive pronation that can contribute to pain,” says Alex Kor, DPM, MS, a podiatrist in Lebanon, Ind. “By controlling this abnormal motion, the patient is usually able to perform normal daily activities with little to no pain.”
