I still remember my first half marathon. By mile 8, my knees were screaming, my heels were on fire, and I swore to myself I’d never run again. Then, at the finish line, a fellow runner noticed me limping and casually said, “Man, you need to get yourself some gel insoles.” Honestly, I thought he was exaggerating—like how much difference could a thin layer of squishy material make? Turns out, quite a lot.
Gel insoles for running shoes have become one of those secret weapons for runners who want comfort, cushioning, and a bit of extra protection from the constant pounding of pavement. But here’s the thing: not all gel insoles are the same, and not everyone needs them in the same way. So, let’s break this down, not in some boring robotic comparison chart, but in a way that feels like a runner talking to another runner.
Why Runners Even Think About Insoles
Running is brutal on the feet. Even with the best pair of running shoes, the repetitive impact—thousands of steps per session—can lead to sore arches, shin splints, knee pain, or that stabbing heel ache known as plantar fasciitis.
Think of your shoes like the suspension system of a car. They absorb shock, stabilize you, and keep things aligned. But when you add gel insoles, it’s like upgrading that suspension. Suddenly, the ride feels smoother.

Podiatrists often say:
- Gel insoles help reduce micro-shock waves traveling up your legs.
- They can distribute pressure more evenly across the foot.
- They may prevent overuse injuries in runners logging long weekly miles.
One sports medicine doctor I spoke to compared them to “an extra mattress topper for your feet.” Shoes alone are the mattress—firm and supportive. Insoles are the plush layer that adapts to your body.
My First Pair of Gel Insoles: A Mini-Story
The first pair I tried wasn’t anything fancy. They were a cheap drugstore brand. Sliding them into my old pair of Asics, I didn’t expect miracles. But after a 5K run, I noticed something small but important: my calves weren’t as tight, and my heels didn’t throb when I took off my shoes.
It wasn’t like running on clouds (that’s an exaggeration brands love), but it felt closer to running on damp grass rather than hard concrete. Subtle, but noticeable. That’s when I started paying attention to which brands were worth it.
How Gel Insoles for running shoes Actually Work (Without the Marketing Fluff)
At their core, gel insoles use silicone-based materials that compress and bounce back with each step. Unlike foam, which flattens over time, gel tends to maintain its cushioning a little longer.
Key things happening when you run with gel insoles:
- Impact reduction → less stress on joints.
- Pressure redistribution → heel and forefoot feel less “hot.”
- Energy return (mild, not magical) → a bit of bounce.
- Adaptability → some gels mold slightly with heat and use.
And no, they don’t magically fix bad running form or cure injuries overnight. But they can make a noticeable difference in comfort, especially during long runs.
Who Should Consider Gel Insoles?
Not every runner needs them. If you’re lightweight, have neutral arches, and run short distances, you might never think about them. But for many runners, gel insoles are like that supportive friend who always has your back.
You might want to consider them if:
- You’re a heel striker who often feels heel pain.
- You’re logging high mileage weekly (20+ miles).
- You run mostly on roads, sidewalks, or other hard surfaces.
- You’ve had recurring plantar fasciitis or shin splints.
- You just want extra comfort for recovery runs.
One marathoner told me he doesn’t train with them all the time, but he always pops them in for long runs over 15 miles. His words: “It’s like an insurance policy for my feet.”
Popular Gel Insoles That Runners Swear By
I’ve tested a handful myself, and I’ve also listened to what other runners, podiatrists, and weekend joggers say. Below are some standouts. Notice, I won’t use the same boring “Pros & Cons” template every time—because honestly, no one talks like that in real life.
Let’s be real—almost everyone’s first insole experience is Dr. Scholl’s. They’re everywhere, from Walmart aisles to pharmacy shelves.
When I slipped these into my Brooks Ghosts, the immediate impression was cushioning. Not “soft pillow” cushioning, more like “ahh, finally something between me and the road.”
What I liked:
- The gel pods in the heel and forefoot actually did absorb some of that harsh strike.
- They felt instantly comfortable (no break-in needed).
- At around $20, they’re a low-risk experiment.
But here’s the catch. After about 60–70 miles, I noticed they began to flatten. One runner on Reddit put it perfectly: “They’re like chewing gum—great for the first few minutes, then you just want a fresh piece.” So yeah, they’re not built for marathon training, but if you’re starting out or want a budget-friendly comfort boost, these are a decent intro.
Now, this one surprised me. A friend recommended them when I complained about shin splints. At first, I wasn’t sold—they felt heavier than I expected. But on the run, that extra material translated into more stability.
- The arch support isn’t aggressive, but it’s there.
- The heel cushioning feels firmer than Dr. Scholl’s, which I appreciated on long runs.
- They fit into most neutral shoes without trimming drama.
One reviewer compared running in these to “finally upgrading from a wooden park bench to a padded chair.” Not luxury, but just enough to make sitting longer (or in this case, running farther) enjoyable. My only gripe? They can feel warm in hot weather. The gel doesn’t breathe as much as foam-based insoles.
This brand isn’t as common in drugstores, but athletes know it. I tried these in my Saucony Endorphins during recovery runs. They don’t scream cushion—rather, they spread pressure evenly.
Instead of that “bouncy” feel, these were more balanced. Imagine laying a yoga mat under your feet—soft, but not sink-in soft. Podiatrists actually like Spenco because they emphasize alignment and shock absorption together.
One coach told me he recommends Spenco to runners who struggle with hot spots—that burning sensation under the ball of the foot. And honestly, I noticed less of that when using them.
Drawback? They’re bulkier, so not every shoe welcomes them without feeling cramped.
PowerStep Comfort Cushioning Gel Insoles
Okay, now we’re entering premium territory. These aren’t just gel—they combine EVA foam with gel zones, plus actual arch support.
I’ll be honest: slipping them into my Nikes made me think, “This feels overbuilt.” But after a 10-mile long run, my knees felt fresher than usual.
Why? Because they don’t just cushion; they guide your foot. They reduce overpronation (that rolling inward motion) without feeling stiff like orthotics.
One runner on a Facebook group described them perfectly: “They feel like a firm handshake for your feet—supportive, not clingy.”
The downside? Price. They’re often $35–$50. But if you’ve dealt with recurring injuries, that cost feels small compared to physical therapy bills.
Dr. Scholl’s Heel Cushions
Not everyone wants full insoles. Sometimes, the pain is isolated—like that stabbing heel pain first thing in the morning. For that, gel heel cups can be game-changers.
I used Tuli’s Gel Heel Cups during a plantar fasciitis flare-up. They don’t change your shoe’s fit much, but they cocoon the heel. Running still hurt, but walking after runs? Way less miserable.
For runners with localized heel pain, these small add-ons are underrated.
Not Just Comfort: The Injury Prevention Angle
It’s easy to dismiss gel insoles as comfort gadgets, but there’s more going on. Sports podiatrists emphasize that insoles can help:
- Reduce plantar fasciitis flare-ups (especially gel heel support).
- Minimize shin splints by dampening repetitive stress.
- Lower knee strain for long-distance runners.
- Help with metatarsalgia (that forefoot burning pain).
I once interviewed a podiatrist who said something that stuck:
“Think of insoles like sunglasses. Do they cure vision problems? No. But they reduce strain so you can function longer without discomfort.”
That sums it up. They’re not a cure, but they can make running sustainable, especially as mileage adds up.
Mistakes Runners Make With Gel Insoles
I’ve made some of these myself, so let me save you the trouble:
- Using old insoles forever → Gel compresses over time. Most need replacing every 3–6 months if you’re running consistently.
- Stacking insoles → Don’t double them up. It changes shoe volume and messes with biomechanics.
- Ignoring shoe type → Not all shoes need gel insoles. Max-cushion shoes + gel = mushy instability.
- Expecting them to fix injuries → They help, but if you’re injured, rest and treatment matter more.
One funny story: a buddy once shoved his gel insoles on top of his shoe’s existing insole without trimming. He ended up with blisters the size of grapes. Lesson: follow the trim-to-fit instructions.
Care and Maintenance
Gel insoles aren’t high maintenance, but a little effort goes a long way:
- Pull them out after sweaty runs to air dry.
- Hand wash with mild soap if they start smelling.
- Don’t leave them in hot cars (the gel can warp).
I learned this the hard way. Left my pair in the trunk on a July afternoon, and when I put them back, they felt lopsided. Like running on a melted gummy bear.
Do Gel Insoles Affect Performance?
Here’s a hot debate. Some runners argue that insoles add weight or change shoe dynamics. Technically, yes—they add a few grams. But unless you’re an elite chasing seconds, comfort usually outweighs the micro-weight penalty.
Personally, I’ve run PRs with insoles and without. The difference was more about how fresh my legs felt after training. For recreational runners (which is most of us), staying injury-free matters far more than shaving a few grams.
Alternatives to Gel Insoles
What if you’re not sold on gel? There are options:
- Foam insoles → Lighter, often more breathable, but wear out faster.
- Orthotics → Custom, pricey, but medically corrective.
- Hybrid insoles (gel + foam) → Like PowerStep or Superfeet, giving you balance of cushion + structure.
One ultramarathoner told me he cycles between gel and foam insoles depending on the distance and terrain. Trail = foam for agility, road = gel for impact absorption. Smart strategy.
My Final Take (Personal Advice)
After years of running with and without gel insoles, here’s my honest conclusion:
- If you’re new to running, they’re not essential. Focus on good shoes first.
- If you’re starting to feel the usual aches—heel pain, sore arches, tight shins—then gel insoles can extend your comfort zone.
- Don’t expect miracles. They won’t make you faster, but they’ll make training feel better. And in running, how you feel often determines how long you stick with it.
For me, gel insoles are like that friend who doesn’t solve your problems but makes the journey less painful. When I’m gearing up for a long run on concrete roads, I slide them in without thinking twice. So, should you get them? If you’ve ever finished a run and thought, “My legs could go longer, but my feet are screaming,” then yes—give them a try. Worst case, you’re out $20. Best case, you rediscover the joy of running without wincing at every step.
FAQs
Are gel insoles good for running every day?
They can be, but it depends on your shoe type and running style. If you’re logging high weekly mileage on hard surfaces, gel insoles can help reduce foot fatigue. But if you already use highly cushioned shoes (like Hoka Clifton or ASICS Nimbus), adding gel might make the shoe feel too soft.
Do gel insoles help with plantar fasciitis?
Yes, especially gel heel cups or full-length insoles with extra heel support. They don’t cure plantar fasciitis, but they relieve pressure on the fascia and reduce morning heel pain. Many podiatrists recommend them as part of treatment.
How long do gel insoles last?
On average, about 3–6 months with regular running. Heavy runners or those logging high mileage may need replacements sooner. Once the gel feels flat or uneven, it’s time to swap.
Can I wash gel insoles?
Yes, gently by hand with mild soap and warm water. Never toss them in the washing machine or expose them to direct heat—they can warp or lose cushioning.
Are gel insoles better than foam insoles?
Not always. Gel excels at shock absorption and heel cushioning, while foam insoles often feel lighter and more responsive. Some runners even switch between them depending on distance and terrain.
Do gel insoles make you run faster?
No magic speed boost here. They’re more about keeping you comfortable so you can train consistently. Indirectly, that can help you run better races because you’re less likely to skip workouts due to pain.
Can gel insoles replace orthotics?
No. Orthotics are custom medical devices designed for biomechanical correction. Gel insoles are comfort accessories. If you have serious alignment issues, a podiatrist is the better route.
Should I remove the shoe’s original insole before inserting gels?
Usually, yes. Most running shoes have removable stock insoles. Take them out before adding your gel insoles to prevent cramping your foot.
Final Runner’s Note
If you’ve made it this far, you’re probably either (a) already nursing sore feet or (b) trying to prevent future injuries. Either way, let me tell you—gel insoles are not hype. They’re small, simple, sometimes imperfect, but they do make running more sustainable.
I’ve had days when I almost quit running because of nagging heel pain. Then I experimented with insoles, tweaked my shoes, and suddenly running felt fun again. Not easy—running is never easy—but manageable. And that’s all you really need to stay consistent.
So, if you’re curious, grab a pair. Worst case, you lose a few bucks. Best case? You add a new layer of comfort that keeps you running longer, happier, and with fewer grimaces at the end of each session.
At the end of the day, running is about joy and freedom. If a gel insole helps you keep that joy alive—even just a little—then it’s worth every penny.
