Best Insoles for Running Shoes 2026
Best Insoles for Running Shoes 2026
Most running shoes come with flimsy, generic insoles that do almost nothing. Theyâre placeholders - thin foam slabs that wear flat within a few weeks. Upgrading to a proper aftermarket insole can transform a good shoe into a great one, adding support where you need it, cushioning where it matters, and a custom-feeling fit without the custom price tag.
Iâm not talking about those Dr. Schollâs inserts you grab at the pharmacy. Running-specific insoles are engineered for the forces of repetitive impact, the biomechanics of a running gait, and the sweat levels that come with putting in miles. Theyâre thinner, more responsive, and designed to work with - not against - your shoeâs existing midsole.
Whether you need arch support for flat feet, extra cushioning for high-mileage weeks, or a more secure heel lock, thereâs an insole on this list that will help. Hereâs what I recommend after researching dozens of options over the past year.
Comparison Table
| Insole | Price | Arch Support | Cushioning | Best For | Profile |
|---|---|---|---|---|---|
| Superfeet Run Comfort | $55 | Medium-high | High | All-round comfort + support | Medium |
| Currex RunPro | $50 | Customizable (3 profiles) | Medium | Biomechanical fit | Low-medium |
| Spenco Total Support | $30 | Medium | Medium-high | Budget all-rounder | Medium |
| Powerstep Pinnacle | $40 | Medium-high | Medium | Plantar fasciitis relief | Medium |
| SOLE Active | $50 | High (heat moldable) | Medium | Custom arch fit | Medium-high |
Superfeet Run Comfort - Best All-Round Running Insole
The Superfeet Run Comfort is my top pick for most runners. It delivers the best balance of arch support, cushioning, and responsiveness Iâve found in an aftermarket insole. The foam is high-density enough to maintain its shape over months of use, but soft enough to absorb impact during long runs.
The arch support is structured without being aggressive - it guides your foot without forcing it into an unnatural position. The deep heel cup provides excellent stability and keeps your foot centered in the shoe. Superfeet uses their proprietary carbon fiber stabilizer cap for torsional rigidity, which helps with overpronation control.
Iâve run over 400 miles on a pair and theyâre still performing well. They fit most running shoes without crowding the toe box, and the thin profile means they donât alter the shoeâs stack height significantly. If you only try one insole, make it this one.

Currex RunPro - Best for Biomechanical Fit
Currex takes a different approach than most insole brands. Instead of one-size-fits-all, they offer three arch profiles (low, medium, high) that you select based on your foot type. This means you get a semi-customized fit without the $200+ price tag of custom orthotics.
The RunPro model is their running-specific option with a dynamic arch support that flexes with your gait. The cushioning is moderate - enough to absorb impact but not so much that you lose ground feel. The low-profile design works well in racing flats and minimal shoes where space is tight.
What I like most is the anatomical fit. Currex insoles follow the natural contour of the foot more closely than any other off-the-shelf option Iâve compared. They feel like they belong in the shoe rather than sitting on top of the existing platform.
The downside: theyâre not the most durable. After 300 miles, the foam starts compressing noticeably. At $50, thatâs acceptable but not exceptional.
Spenco Total Support - Best Budget Option
The Spenco Total Support delivers surprisingly good performance at just $30. It wonât match the Superfeet or Currex in durability or precision fit, but for runners who want an affordable upgrade over stock insoles, itâs hard to beat.
Arch support is moderate and broadly comfortable across different foot types. The gel heel insert provides noticeable impact absorption, and the polyester top fabric manages moisture decently. The 3-pod cushioning system in the metatarsal area helps with forefoot comfort during longer runs.
These are a great option if youâre new to aftermarket insoles and want to experiment without committing to a $50+ product. Theyâre also useful as a backup pair for rotating between shoes. Durability is the main weakness - expect to replace them every 200-250 miles.
Powerstep Pinnacle - Best for Plantar Fasciitis
If youâre dealing with plantar fasciitis or heel pain, the Powerstep Pinnacle should be your first stop before considering custom orthotics. The semi-rigid arch support and deep heel cradle specifically target the biomechanical patterns that contribute to plantar fascia irritation.
The built-in arch support is firmer than the other options on this list, providing genuine structural correction rather than just cushioned comfort. The double-layer cushioning (EVA foam base + VCT top layer) absorbs heel strike impact effectively. Many runners report significant pain reduction within 1-2 weeks of consistent use.
The firm support does mean a brief break-in period. The first few runs might feel unusually supportive - almost intrusive. Give it 4-5 runs before judging. Most runners adapt quickly and then canât go back to unsupported insoles.
At $40, these are also the best value on this list if you have a specific biomechanical need. Theyâve saved many runners from spending $300+ on custom orthotics.

SOLE Active - Best Custom Fit
SOLE Active insoles are heat-moldable, meaning you can bake them in your oven and then stand on them while they cool to create a personalized arch shape. This gives you roughly 70% of the customization of professional orthotics at a fraction of the cost.
The molding process is simple: heat at 200°F for 2 minutes, place in your shoe, and stand for 2 minutes while they conform to your foot. The result is an insole that matches your unique arch height, heel shape, and foot width perfectly.
For runners with unusual foot shapes - very high arches, asymmetric feet, or wide forefeet with narrow heels - the SOLE Active provides a fit that off-the-shelf insoles canât match. The cork base is durable and continues to mold slightly with wear over the first few weeks.
The trade-off: theyâre thicker than other options, which can feel tight in shoes with already-snug fits. Size down in the insole or choose shoes with removable insoles and generous interior volume.
How to Choose the Right Insole
Assess your need first. Not everyone needs an aftermarket insole. If your shoes feel comfortable and youâre injury-free, stock insoles are fine. Consider an upgrade if you experience:
- Arch fatigue during long runs
- Heel pain (especially first thing in the morning)
- The shoe feeling âflatâ or unsupportive after a few months
- Blisters from foot sliding within the shoe
Match the profile to your shoe. Insoles come in low, medium, and high profiles. A high-profile insole in a shoe with existing high cushioning will crowd your foot. Generally: use low-profile insoles in racing flats, medium in daily trainers, and reserve high-profile for stability shoes or boots.
Consider your arch type. Flat feet benefit from structured support (Powerstep, SOLE). Neutral arches do well with medium support (Superfeet, Currex medium). High arches often prefer more cushioning and less rigid support.

Insole Care and Replacement
When to replace: Most running insoles last 200-400 miles, depending on quality and your weight. Signs of wear include visible foam compression, reduced bounce-back when you press the heel, and any cracking or delamination.
Cleaning: Remove insoles after runs and allow them to air dry. For deeper cleaning, hand wash with mild soap and water. Never machine wash or tumble dry - heat destroys foam structure.
Rotating insoles: Just like rotating shoes, having two pairs of insoles and alternating extends the life of both. The foam recovers between uses.

FAQ
Do aftermarket insoles work with all running shoes?
Most aftermarket insoles work with most running shoes, but fit varies. Youâll need to remove the stock insole first (most are removable - just pull them out). The aftermarket insole should lay flat without bunching or curling at the edges. Trim-to-fit models let you cut the insole to your shoe size using the marked guidelines on the bottom. Shoes with glued-in insoles (some racing flats) wonât work well with replacements.
How long do running insoles last before they need replacing?
Expect 200-400 miles from quality insoles, with premium options like Superfeet lasting toward the upper end and budget options like Spenco needing replacement sooner. Youâll know itâs time when the foam feels permanently compressed, especially in the heel and arch areas. A good test: press your thumb into the heel - if it doesnât bounce back within a second, the cushioning is dead.
Can insoles fix overpronation?
Insoles can help manage mild to moderate overpronation by providing arch support that reduces the degree of inward roll. Theyâre not a permanent fix for severe biomechanical issues, but for many runners, a supportive insole combined with a stability shoe is enough to run comfortably and injury-free. If your overpronation is severe or causing recurring injuries despite insole use, consult a sports podiatrist about custom orthotics.
Are custom orthotics better than over-the-counter insoles?
Custom orthotics are prescribed by podiatrists and molded precisely to your foot. Theyâre superior for addressing specific medical conditions (severe flat feet, chronic plantar fasciitis, leg length discrepancies). However, they cost $300-600 and arenât always necessary. Many runners find that quality over-the-counter insoles ($40-55) provide 80% of the benefit at 10% of the cost. Start with a good OTC insole and only pursue custom orthotics if the problem persists after 4-6 weeks.
Should I put insoles in all my running shoes or just one pair?
Ideally, use insoles in all shoes you run in regularly. Your feet adapt to the support and removing it can feel uncomfortable or increase injury risk. That said, the cost adds up quickly if you rotate 3-4 pairs of shoes. A practical approach: use insoles in your daily trainer and long-run shoe (where you spend the most time), and skip them in racing flats or short-run shoes where minimal time on feet reduces injury risk.
Final Thoughts
The right insole wonât fix bad shoes, but it can make good shoes significantly better. For most runners, the Superfeet Run Comfort is the safest all-round choice - excellent support, good durability, and works in virtually any shoe.
If youâre dealing with plantar fasciitis, grab the Powerstep Pinnacle before spending money on custom orthotics. And if you want the closest thing to a custom fit without the specialist appointment, the SOLE Active heat-moldable option is genuinely impressive.
Start with one pair in your primary training shoe. Run 50 miles and see how it feels. Youâll probably wonder why you waited so long.
