When it comes to choosing the right insole for skateboarding or high-impact sports, your comfort and safety depend on more than just brand loyalty. It is a matter of science and reliability. The debate between the Nike insole vs FP Insole is no longer just about feel. It is about facts, data, and technology. And the best way to choose the right winner is to rely on empirical evidence, because numbers do not lie.
If you are also trying to find the answer to the above conundrum, you have landed at the right place. In this comprehensive comparison, we will break down why FP Insoles aren’t just winning, they are dominating the market, especially when it comes to impact protection and shock absorption. Using non-Newtonian materials, military-grade tech, and lab-tested performance, FP Insoles emerge as the superior choice over Nike SB stock insoles in nearly every category that matters. So read on!
The Lab-Tested Verdict: Nike Insole vs FP Insole
The turning point in the Nike insole vs FP Insole discussion comes from a lab-tested 20-joule impact comparison between the Nike SB Stock Insole and the FP Kingfoam Elite Insole. Here’s what is revealed:
• Nike SB Stock Insole Impact Reading: ~12,000 kN
• FP Kingfoam Elite Insole Impact Reading: <6,000 kN
Let that sink in. FP absorbs nearly 50% more impact than Nike SB stock insoles. It is important to highlight that this is not just a minor edge; this is the difference between walking away from a session and nursing a heel bruise that could sideline you for weeks.
Medical experts agree that heel bruising typically starts when impact forces exceed 7,000-8,000 kN. Nike’s reading? Well, it is clearly into the red zone. FP insole on the other hand stays well below the injury threshold, thus keeping your joints safer and your session longer.

Why FP Insoles Are Built Differently
Here’s what makes FP stand tall in the Nike Insole vs FP Insole debate:
ü Non-Newtonian Fluid Core
FP’s insoles feature a core made of non-Newtonian material that stiffens on impact to disperse energy, then softens again for comfort. This tech reacts dynamically to each step, jump, or landing, catering to your needs as you move.
ü TPU Support Layer
Unlike rigid insoles, the TPU (thermoplastic polyurethane) support layer in FP Insoles reinforces the arch while maintaining flexibility. This dual-action provides both structure and adaptability in real time.
ü Lab-Tested to Absorb 90% of Shock
ASTM F1614 lab tests have confirmed FP Insoles absorb over 90% of shock energy, vastly outperforming conventional foam and gel technologies.
ü Heat-Moldable Quality
The ultimate game-changer in the Nike insole vs FP insole debate is the heat-moldable flexibility offered by Footprint. The material used in FP insoles molds according to the shape of your feet, enabling you to have a custom-like, prescription-level experience, which is affordable.
ü Zero Break-In Time and Moldable Fit
FP Insoles mold to the unique shape of your foot, offering a custom-like fit without the painful break-in period that plagues most high-performance insoles.
Real-World Application: FP Insoles in Action
Let’s take a look at four of FP’s best-selling models and how they blow Nike SB’s stock insole out of the water.
Kingfoam Orthotic Elite FP Insoles
• Force transfer: 6,500 – 6,800 kN
• Heel/Toe thickness: 8mm / 6mm
• Dual-density arch chamber dynamically adapts to movement
• NASA-grade materials for supreme shock protection
• TPU reinforcement increases endurance and cushioning
• Break-in period: 3–5 days for an ideal fit
Built for skaters, runners, and hikers who want a bulletproof ride underfoot. Compare this to a standard Nike SB stock insole, and the FP wins every time.
FP Gamechangers Pro Sports Insoles (3D Custom Arch Support)
• Force transfer: As low as 7,500 kN
• Quantum Heel Technology offers superior stabilization
• Comfort Plus Foam stays responsive across temperatures
• Built with TPU top layer for maximum durability
• Shock absorption: Nearly double that of the original Gamechangers
• Ideal for high-impact sports and the daily grind
These insoles offer professional-level shock absorption with a slim profile that fits almost any shoe. The technology is patent-pending, but the performance is proven.
FP Kingfoam Orthotic Fluidx Insoles
• Force transfer: as low as 6,400 kN
• FluidX Arch Technology adapts in real time
• Provides unmatched comfort for all-day wear
• Designed for performance, work, and long hikes
• NASA-grade shock absorption foam
• Dynamic adaptability = less joint fatigue
If you’re serious about your sport or your job involves long hours on your feet, this insole turns each step into a soft, supported movement. In the Nike insole vs FP Insole matchup, this is what next-gen tech looks like.
• Built with 3D custom arch support for flat feet and high arches
• 2–3x more durable than previous models
• TPU top layer + Comfort Plus foam
• Shock absorption: nearly 2x original Gamechangers
• Ideal for anyone who wants pro-grade comfort with long-lasting support
With zero break-in time and instant moldability, these insoles feel custom-made. Meanwhile, the average Nike SB insole offers minimal support and shock dispersion.

Reason Why Nike SB Stock Insoles Fall Short
Nike’s SB line is stylish, no doubt. But when it comes to Nike insole vs FP insole performance comparison, the stock insoles are simply not built for real protection. The foam is basic, the arch support is negligible, and the shock absorption is insufficient at best.
In high-impact activities like skateboarding or trail running, using an underperforming insole isn’t just uncomfortable, it is dangerous. With readings as high as 12,000 kN, Nike SB insoles leave you at risk for:
• Heel bruises
• Joint fatigue
• Long-term injuries to ankles and knees
In contrast, FP Insoles offer dynamic protection with scientific precision.
The Final Verdict: Nike Insole vs FP Insole
In the head-to-head Nike insole vs FP Insole battle, there’s a clear winner. If truth be told, the contender is not even close, as the lab tests suggest. To wrap it up, if you’re skating hard, hiking long, or standing all day, you need more than just a name-brand insole. You need real protection that is backed by biomechanically engineered foot insoles. So, in the debate of Nike insole vs FP Insole, FP wins through engineering, lab-proven impact reduction, and next-gen material science. This is your chance to pick FP insoles that absorb the hit and successfully protect you from avoidable injuries and muscle damage.
