Best Running Insoles of 2026

Three arch profiles is what sold us on the RunPro. Every other insole here arrives in a single shape and asks your foot to adapt; this one is ordered in low, medium, or high, so the curve under your midfoot lands where your own arch does. We tested the medium-arch pair in a size large, and that fit is the reason it sits at the top of this list — nothing about the support feels generic.

The build backs the idea up. PORON foam takes the sting out of the heel strike without turning mushy, a deep heel cup keeps your foot centered when you pick up the pace, and the mesh top layer stays reasonably dry. What we watched for was collapse — whether the arch would flatten after a few long runs — and it held its shape better than the softer pairs in this set. Arch support is where the RunPro separates itself most clearly, and it is also sold for both men and women, which makes sizing one less thing to think about.

Ordering takes thirty seconds of thought, but they are the right thirty seconds: the profile is the real decision, and a medium arch in the correct size beats a high arch that digs in. If you have never checked which you are, the wet-foot test in our buying guide settles it in under a minute. After that there is very little to complain about beyond what you pay at checkout.

Firm is the word. The Women's High Impact does not try to be a soft insole, and if you have been shopping for something pillow-like, this is not it — the arch is structured, the platform is stiff, and that is exactly why we rate it the best choice here for high-impact running.

What the firmness buys you is control. Under the midfoot the pair settles and stays put, and the shoe stops rolling inward at the end of a long run — the kind of thing you notice the day after a hard session. It is also the pair we point to first when plantar fasciitis or an angry Achilles is part of why someone is shopping: a structured insole that holds the arch up makes more sense for that foot than a soft one that lets it drop.

Break-in is short. The arch feels pronounced for the first run or two, then it stops announcing itself and the insole disappears into the shoe. One thing worth knowing before you order: this is a women's-specific fit, so men should look at a different pair entirely rather than sizing up in this one.

Two things decide whether the Athlete works for you: what you want to spend, and how much room your running shoe has inside. On the first, it is the value play here — a full-length PU foam and gel insole with heel-to-toe cushioning for a fraction of what the premium pairs cost.

On the second, it is a substantial insole. Ours filled out a daily trainer nicely and cushioned a long, easy run without going flat under the heel, and the top cover kept the shoe drier than the stock sockliner did — a small thing that stops being small in July. What it does not do is squeeze into a snug racing shoe; there simply is not the room. Give it a trainer with a removable sockliner, or a work boot, and it behaves.

For everyone else, this is the pair to buy if you want premium-feeling cushioning without the premium price, and the one we are happiest to buy again. It is also the sort of insole that ends up in walking shoes and work boots rather than staying in one pair of runners.

Dr. Scholl's built this one around three zones — heel, arch, forefoot — with a reinforced arch and a Polygiene top cover meant to keep odor down between washes. It is a women's insole, it is trim-to-fit, and it is the least expensive running-specific pair here.

What we noticed in testing is how little it changes the shoe. There is no break-in, no pressure point under the arch, and the heel-to-toe transition stays smooth — the kind of insole you put in and forget about, which is the highest compliment a budget insert can get. It is also the pair we are most likely to buy a second of, so one set of shoes does not have to give up its insole every time we rotate.

Because it is trim-to-fit, cut against the shoe's stock insole rather than eyeballing it, and start slightly wide of the outline — you can take more off the toe, and you cannot put it back. That is a minute's work for an insole that will otherwise disappear into the shoe.

The heel is where the Polysorb does its work. A SpenCore pad sits under the heel bone, a crash pad runs under the forefoot, and the heel cup is deep enough that your foot sits down inside it rather than on top. For a cross-trainer it is a surprisingly plush piece of kit.

Softness is the point. We appreciated it on treadmill days and on gym floors, and the metatarsal padding earns its keep when the ball of your foot is what aches at the end of a session. It is a comfort insole first, the kind of thing that makes a stiff cross-trainer feel forgiving.

Fitting it is the one place to be deliberate. Between the heel pad and the foam it takes up more room than a stock sockliner, so it wants a shoe with a removable liner and a little depth; a racing flat will feel crowded. Used that way it is a comfortable option for mixed training rather than a replacement for a running-specific support insole.

Cheapest in this set, and it does not pretend otherwise. Dr. Scholl's Sport is a shock-absorbing insert with flexible side-to-side support, sold for men across multiple sports — gym shoes, golf shoes, hiking boots, and the walking you do the rest of the day.

That breadth is the appeal. As a running insole it is basic: the arch is a firm shell rather than a shaped support, and you can feel it under the midfoot when you are pushing the pace. As an insole for everything else — the gym bag, the boots you wear on a muddy trail, the shoes you stand in all day — it is a cheap way to make a disappointing pair of shoes wearable again.

So this is a utility pick rather than a running upgrade. If you log real miles, spend more; if you want one cheap pair to rescue three pairs of shoes, this is the one we grab.
