8 Best Insoles for Flat Feet, According to Podiatrists in 2023

Dr. Sims recommends Superfeet’s insoles for their semi-rigid design and deep heel cup, both of which help keep feet stable and comfy all day long. The popular Green insole is made to be particularly supportive. It’s thick with a firm level of cushioning that won’t feel too squishy, and the high arch provides a nice amount of lift. Several reviewers with flat feet noted that the arch felt great and alleviated some of their foot pain, but you may also want to start with a pair that has lower arches to see which suits your feet better.  

Powerstep is another preferred brand for Dr. Sims, and this particular insole is made specifically with flat feet in mind. It’s relatively stiff yet cushioned—so it should feel comfy, but not like it’s collapsing. Also, its arch is on the low side, which provides some pressure relief without significantly raising your foot.

According to Dr. Lobkova, people with flat feet can often develop plantar fasciitis, an inflammation of the band of tissue across the bottom of the foot that can lead to heel pain. A thick insole, like this option from Walk-Hero, can help reduce that discomfort: It’s cushioned enough to absorb the impact from your footsteps, and features a deep heel cup to help keep your foot in a comfortable position all day long.

Designed by a podiatrist dealing with his own foot pain, this insole from Samurai is made to reduce the discomfort that results from both flat feet and plantar fasciitis. It has a slightly flexible, responsive orthotic core built into the midfoot and heel, which allows it to both bend with your foot and prevent it from rolling inward. This insole is a little thinner than the other options on our list, so it’s a good pick if you want something that won’t add a ton of bulk inside your shoes.

Walkomfy’s Flat Feet insole stabilizes and aligns the base of your foot, thanks to its unique design, which provides targeted support to different parts of the foot: The heel is padded with a springy foam to reduce shock, while the arch is reinforced with sturdy cork. Plus, the comfy memory foam midlayer, found throughout the sole, absorbs sweat.

This is another top-rated Superfeet insole, made of the same dense foam as the Green iteration, but with a much lower profile. The Blue version also lifts the arch a little less, which might make it a comfier introductory option for people who are new to using insoles.

You can make your favorite workout shoes and sneakers more supportive with the Spenco Polysorb Insole, which is designed to reduce pain even during high-impact activities. It has a highly padded heel, pressure-relieving forefoot, and a slightly lifted arch. Reviewers note that the arch is just high enough to make a difference in how their shoes feel: “The exact support I need for my flat feet. These make all shoes a dream,” one person wrote.

The Pinnacle Maxx Support insole from Powerstep is seriously sturdy—it has a firm, mid-height arch and a deep, angled heel cup that’s meant to prevent your foot from slipping around or rolling inward. It’s still comfortable and cushioned, so you can wear it in your everyday shoes without concern.
