Looking for support, cushioning, and shock absorption? Some can even be trimmed to fit.

If you have flat feet, overpronation, or a combination of the two, adding insoles that fit well to your footwear can offer many benefits. The best insoles for overpronation and flat feet are made from firm yet comfortable material, providing arch and heel support and cushioning, potentially reducing overpronation. They can also “absorb shock and reduce stress on pressured areas of the foot, helping alleviate pain and discomfort,” podiatrist Daniel Pledger wrote in an email to Bustle. Over Pronation Insoles

Read on to get the scoop on the five best insoles that you can buy to help with overpronation and/or flat feet — your feet will thank you!

These insoles from WALKER HERO COMFORT AND SUPPORT are incredibly popular on Amazon — boasting a 4.3-star rating overall after 66,000-plus reviews — with fans noting they’re a particularly excellent choice if you have flat feet and/or overpronation. The insoles are described as “semi rigid,” and they feature memory foam for cushioning and silicone for shock absorption. The deep heel cup ensures your foot stays stable with every step. And the low arch is supportive, yet comfortable.

One Reviewer Wrote: “I have very flat feet, and these are the best insoles i have ever found. they are very comfortable, and the arch support is just right. i like them so much, so i ordered two more pair, and put them in my other shoes.”

Material: Foam, silicone | Arch: Low | Trimmable: No | Available sizes: 13

Superfeet is a brand synonymous with high-quality insoles that last, and this pair from the brand certainly fulfills that description; they can be worn for up to 500 miles before needing to be replaced. The insoles are a medium arch option that’ll stabilize your feet and arches while reducing stress. A layer of high-density foam delivers comfort, a heel cup provides shock absorption, and a plastic stabilizer cap adds structure and support. Another perk? This pick features a coating to help with odor control.

Choose from a range of size options for women, men, and even kids, though this pick is also trimmable for a perfect fit. The medium profile shape won’t take up too much room in your shoes, however, Superfeet also makes an even thinner option with a low arch as well.

One Reviewer Wrote: “Recommended by our podiatrist for flat feet. They really help and make the shoes much more comfortable. Helped to eliminate foot pain from shoes with no support.”

Material: Foam, polypropylene | Arch: Medium | Trimmable: Yes | Available sizes: 8

These insoles from DACAT are one of the more firmer, structured options on this list because they’re made from cork. But don’t worry, they’re still quite comfortable to wear because they boast a cushioned foam layer and a supportive metatarsal pad as well. The insoles offer low to medium arch support and a deep, u-shaped heel cup for plenty of stability. This pick comes in 10 size options, though they’re also trimmable to ensure a great fit.

One Reviewer Wrote: “These inserts are so comfortable and provide tremendous support for my flat feet. They fit perfectly and I did not have to trim them at all to fit in my shoes. Very pleased with this purchase and would buy again.”

Material: Cork, foam | Arch: Low/medium | Trimmable: Yes | Available sizes: 10

The gel material of these insoles from Dr. Scholl's makes them superior when it comes to comfort — they’re a particularly great choice for people who are on their feet for extended periods of time because they have a massage-like effect on the feet. Plus, they have serious shock absorption. The insoles offer medium arch support that’s reinforced to not collapse (perfect for those with flat feet and overpronation), a heel cup for stability, and a vented design to help your feet stay cool. Replace these insoles after six months of use or at the first signs of wear.

One Reviewer Wrote: “I am constantly on my feet at work everyday. I do not have to time to sit down and take a break. These have saved my flat feet from aching and hurting. I can enjoy my day without complaining.”

Material: Gel [[Think there’s other stuff in there too?]] | Arch: Medium | Trimmable: Yes | Available sizes: 4

With a price tag of just $10, these insoles from Happystep are a budget buy that is too good to pass up. They’re made entirely from high-density memory foam, making them a super cushiony option that’ll mold to your feet for a more custom fit — don’t worry, the medium arch is quite supportive for those with overpronation and flat feet. “Cushions and comforts my flat feet and provides support that no other insole can,” explained one fan on Amazon.

The insoles also offer a smooth velvety exterior for softness and a deep, u-shaped cup for stability. This pick is a medium-width option, but a wide width is also available. These insoles come in three size options that are trimmable.

One Reviewer Wrote: “oh my gosh, these happy feet cushions are the bomb. I have flat feet and my heels take a beating cause I am on my feet for hours at a time. This product saved me from so much pain.”

Material: Foam | Arch: Medium | Trimmable: Yes | Available sizes: 3

How often should I wear insoles if I have overpronation and/or flat feet? “People with flat feet should wear supportive shoes and insoles as often as possible to avoid symptoms and progressive collapse of the arch,” explains Dr. Roussel.

How long can I wear a pair of insoles before they need to be replaced? Many of the experts that Bustle reached out to indicated the answer to this can vary based on factors such as how often you use the insoles, your activity level, the material’s durability, etc. And some brands will even list specific information about the longevity of their insoles. However, as a general rule of thumb, Dr. Pledger indicates that “most insoles will need to be replaced after [six] months to a year of use.” And Dr. Roussel notes that “When the insole starts to fade and you see visual damage, or they no longer feel supportive, then it’s time to replace them.”
