Where to Buy the Best Adidas Replacement Insoles in 2026

Finding the perfect pair of Adidas sneakers—whether it's the cloud-like comfort of the Ultraboost, the classic vibe of the Stan Smith, or the pitch-ready feel of the Predator—is a win for any footwear enthusiast. However, even the best shoes have a "hidden" shelf life: the factory insoles.

In the majority of Adidas sneakers, a minimal amount of glue is applied to hold the stock insole in place against the midsole. This glue is usually quite weak in strength. As a result, you can effortlessly lift the insole out of the shoe using just your fingers. However, select Adidas styles—such as the Yeezy collection from Kanye West and the vast majority of Adidas running models—have no glue on the underside of the insole at all.

If you're seeking a high-end insole enhancement, PCSsole replacement insoles deliver superior cushioning, longevity, and arch support. From everyday casual sneakers to high-performance running shoes, PCSsole are engineered to optimize comfort and balance, enabling you to remain active for longer periods with reduced fatigue.

No matter which Adidas model you are wearing, significantly unlacing the shoes will provide better internal access, simplifying the process of pulling out the original inserts and replacing them with PCSsole insoles. After taking out the factory footbeds, gently slide the PCSsole replacements into your Adidas shoes and adjust them until they sit correctly. This entire swap can be completed in under 2 minutes, allowing you to conveniently share a single set of PCSsole insoles across various pairs of footwear.

Pro Tip: In the event that the adhesive on the original insole is stubborn, apply low heat with a hair dryer to soften the glue for easier removal.

Let's face it: the factory-fresh insoles in your Adidas shoes are built for mass production, not individual needs. They're thin, generic foam pads that prioritize lightweight design over ergonomic support. For many, this translates to real discomfort. Imagine slipping into your favorite Adidas NMDs for a weekend hike only to end the day with throbbing arches or misaligned toes. Or worse, pushing through a marathon training session in Ultraboosts where the insoles compress under pressure, leading to uneven weight distribution and potential injury.

1. Superior Arch Support

Most factory insoles are flat. If you have high arches or flat feet (overpronation), this lack of contour can lead to Plantar Fasciitis, shin splints, and knee pain. Upgrading to an orthotic-grade insole provides the structural "bridge" your foot needs to distribute pressure evenly.

2. Enhanced Shock Absorption

While Adidas technologies like Boost and Lightstrike provide excellent midsole cushioning, a high-quality replacement insole adds a secondary layer of impact protection. This is crucial for runners, athletes, or anyone standing on hard surfaces for 8+ hours a day.

3. Extended Shoe Life

By replacing the insole, you effectively "reset" the internal comfort of the shoe. Instead of buying a brand-new pair of sneakers because they feel "flat," a tens-of-dollars investment in premium insoles can make an old pair feel like new again.

Adidas shoes follow standard US sizing, but insoles like PCSsole are sold in half-size increments for added flexibility. To nail the fit:

• Men's Example: A US 10 shoe pairs with PCSsole size 10–10.5.
• Women's Example: A US 8 shoe matches PCSsole size 8–8.5.
• Pro Tip: If you have high arches or wide feet, size up half a size for optimal contouring and pressure relief. Always compare the new insole to your stock one side-by-side.
• Grab PCSsole's sizing chart from their site—it's spot-on for Adidas's half-sizing quirks. A precise match prevents slippage and maximizes the shoe's stability.

Before you can upgrade, you need to clear the way. Most Adidas insoles are "drop-in," but some are lightly glued to the midsole to prevent slipping.

Step-by-Step Removal:

Loosen the Laces: Open up the shoe as wide as possible to give yourself room to work.

The Heel Lift: Reach into the shoe and try to lift the insole at the heel.

Dealing with Glue: If the insole feels stuck, do not rip it out forcefully. This can tear the fabric lining of the shoe. Instead:

Use a hairdryer on medium heat for 60 seconds to soften the adhesive.

Gently slide a flat tool (like a blunt butter knife or a credit card) under the insole to break the bond.

Clean the Interior: Once removed, shake out any debris or dried glue bits so the new insole sits perfectly flat.

When replacing your Adidas shoes, you want a high-quality upgrade that delivers exceptional comfort and durability. PCSsole replacement insoles are designed to enhance your footwear experience, providing better support and performance with every step.

1. PCSsole insoles stand out due to their premium materials and advanced design:

Contoured Arch Support – PCSsole insoles provide optimal alignment, reducing strain on your ankles, knees, and lower back. They adapt to your natural foot shape, whether you have high, medium, or low arches, ensuring proper weight distribution and improved stability.

Superior Cushioning – Built with shock-absorbing materials, PCSsole insoles reduce impact stress, making them ideal for long walks, high-intensity workouts, and daily wear. Their responsive cushioning softens impact and supports your every movement.

Odor-Resistant Material – PCSsole insoles keep your Adidas shoes fresh by preventing bacteria buildup. Their moisture-wicking and antimicrobial properties help control odor, which is especially beneficial for athletes and anyone wearing sneakers for extended periods.

2. Immediate Benefits

The moment you slip PCSsole insoles into your Adidas sneakers, you’ll feel a noticeable difference in comfort and support:

Reduced Foot Fatigue – PCSsole insoles prevent discomfort from prolonged standing or repetitive movements by evenly distributing pressure and providing enhanced arch support. Your feet will feel less strained, even after a full day of activity.

Better Biomechanics – Proper alignment reduces stress on your joints and muscles, improving overall posture and movement efficiency. This is crucial for athletes who rely on precision footwork and anyone experiencing foot pain from poor shoe support.

Enhanced Shoe Comfort – Even the most comfortable Nike shoes can start to feel less supportive as their insoles wear down. PCSsole insoles restore that fresh-out-of-the-box comfort, giving your favorite pair a renewed feel with improved cushioning and support.

Proper care extends an insole's lifespan and keeps your Adidas fresh. Here are some top-of-mind tips:

Always remove stock liners: Prevents cramped toe boxes and ensures a stable fit.

Fight squeaks: Lightly dust the insole’s underside with baby powder or add a thin fabric layer under the forefoot.

Clean regularly: Hand-wash with mild soap, rinse gently, and air-dry for 24 hours. Avoid dryers or direct heat, which can warp EVA or PU.

Rotate pairs: If you wear Adidas daily, keep a backup insole set to reduce wear and allow each pair to dry fully.

Store properly: When not in use, keep sneakers in a cool, dry place to avoid moisture buildup.

Know when to replace: Swap insoles every 6–12 months (or 400–700 km of walking). Watch for compressed heels, persistent odor, or arch support loss.

Tip: Take your PCSsole insoles with you when you try on new shoes. This ensures you get the proper fit no matter which shoe brand or model you buy.

You can purchase specialized orthotic insoles directly from the PCSsole official website.

For "original" Adidas replacements (if you specifically want the exact factory foam), sites like eBay often have sellers who "strip" new shoes, though these lack the orthopedic benefits of a dedicated brand.

Q: Will third-party insoles make my Adidas feel too tight?

A: It depends on the model. If you are replacing the original insole, the fit usually stays the same. However, if your shoes are already very snug, look for the "Ultra-Thin" versions of PCSsole to ensure you still have enough toe-box room.

Q: Can I put the new insole on top of the old one?

A: No. This is a common mistake. Putting one insole on top of another will lift your foot too high, causing your heel to slip out of the shoe and creating uncomfortable pressure on the top of your foot. Always remove the original first.

Q: How do I know when it’s time to replace them?

A: Look for visible cracks in the arch support, thinning of the foam at the ball of the foot, or if you start feeling "phantom" aches in your knees or lower back that weren't there before.

Q: What if my insoles cause initial discomfort?

A: Break-in takes 1-2 weeks; wear gradually. If pain persists, it may be a size mismatch—exchange promptly.
