Best Running Insoles of 2026

A running shoe's factory insole is a flat sheet of foam with a job it quietly stops doing after a few hundred miles. Dropping the Athlete in is the least fussy fix in this group: PU foam with gel through the heel and forefoot, a moisture-controlling top cover, and enough give that the shoe feels new again without turning mushy.

We like the middle it occupies. Some insoles here are soft to the point of vagueness and the Superfeet is a rigid shell; the Athlete sits between, firm enough that your foot does not roll inward on landing and soft enough that the ball of your foot is not aching at the end of an easy ten. It is also sized to the shoe, so most runners will not need scissors, and it is the pair we hand to someone who just wants their trainers to feel better without researching arch profiles.

Volume is the catch. This is a substantial insole, and in a snug racer or a shoe you bought with no wiggle room it takes the space your toes were using. In a roomier daily trainer it disappears underfoot. If your shoes are already tight, size up in the shoe or choose something slimmer rather than forcing it.

The High Impact is the firm one. Put a thumb into the arch of any other pick here and it gives; this shell resists, holding a rigid cradle that keeps its shape when you land on it. That resistance is the whole recommendation. Soft foam absorbs an impact, but it cannot stop a foot from rolling inward, and for some runners that roll is the problem.

It is the pick with the strongest record on foot pain in this set, and plantar fasciitis is the case it is known for. The heel is held without pressing on the ankle bones, which is rarer than it sounds, and trimmed to the shoe it sits flat and stays put instead of creeping forward mid-run. Runners who have spent years buying cheap inserts and replacing them twice a season tend to end up here eventually.

The trade-off is feel, and it is worth being honest about. There is little padding under the ball of the foot, so a runner who wants a plush landing will find this hard and wonder what the fuss is about. It is built to control motion, not to soften the road — if softening the road is the goal, the Sof Sole and the Spenco do that job in this group.

This is one of two women's-specific picks here and the only one aimed squarely at running. Dr. Scholl's builds it on a women's pattern with a three-zone heel-to-toe layout — softer at the heel, reinforced through the arch, cushioned at the forefoot — which smooths the transition from landing to push-off rather than propping the foot up in one spot.

Polygiene is the detail we did not expect to care about. Insoles live in the dampest corner of your kit, and a pair that goes sour gets binned long before the foam is finished; the treatment here targets exactly that, and it is the reason a second pair for the gym bag is easy to justify. In a hot shoe on a summer run, that counts for more than it sounds.

Where it earns its place is as the low-risk entry point. It is cut for women's shoes rather than shrunk down from a men's pattern, so it does not bunch through the midfoot in a narrow trainer, and the ride stays predictable over the shorter daily run or the treadmill session. Runners chasing a marathon or a high arch should look at the CURREX instead; this one is for getting started and staying comfortable.

The Sport is the generalist of this group. Dr. Scholl's builds it as an athletic insole for multiple sports rather than one, and that is how it behaves: gym shoes, walking shoes, hiking boots, a round of golf. Few of the running-specific picks here can move that widely, and the ones that can usually give up cushioning to do it.

It lands closer to a comfort insole than a performance one. The arch is a flexible, moderate shape with side-to-side give rather than a formed cradle, and the cushioning is a broad foam bed instead of a tuned heel-and-forefoot layout. For the runner who owns one pair of shoes and uses them for everything, that is the right compromise; for anyone chasing a personal best, it is not the tool.

It is generous through the length, so larger feet have room to work with, and it trims down easily for a smaller shoe. What we keep coming back to is the versatility: this is the pair that makes a retired set of running shoes wearable for the dog walk, which is the least glamorous and most useful thing an insole can do.

Polysorb foam is the soft end of this group. Spenco puts a SpenCore heel pad and a forefoot crash pad under a light foam body, and the result takes the edge off hard pavement instead of trying to control how your foot moves. The deep heel cup is the part you notice on a sidewalk — it keeps the foot centered without gripping it.

The arch is a soft rise rather than a hard shelf, which is why runners who cannot tolerate firm insoles get along with this one. The shape is a cross trainer rather than a running-specific last, so it settles into a gym shoe or a walking shoe as happily as a daily trainer, and the forefoot padding is where the softness pays off on longer pavement stretches.

The line we draw is between sensitive feet and unstable ones. If your feet bruise on hard ground or your heels complain after a week of concrete, this is the pair to try. If your foot rolls inward and needs holding, no amount of soft foam fixes that, and the firm Superfeet shell is the better answer.
