Why FP Infinity Foam Beats Poron XRD: Arch Support, Temperature & Durability Tested
When high-impact athletes, skateboarders, and active professionals look for replacement insoles, the debate often comes down to performance, longevity, and true impact absorption.
While brand marketing claims are everywhere, putting materials through extreme conditions reveals the real differences between FP Insoles (Footprint) and Remind Insoles.
Below, we break down the engineering, material science, patented arch support technology, and long-term value to show how FP Insoles consistently outperform competitors like Remind.
1. Material Evolution & Temperature Sensitivity
The Timeline of Shock Absorption Tech
- ✓ 2015: Footprint (FP) revolutionized the industry by introducing advanced Non-Newtonian foam insoles designed to instantly harden upon impact to protect joints and absorb shock.
- ✓ 2022: Competitors like Remind finally caught up to basic Non-Newtonian foam concepts, incorporating a small top layer of Poron XRD into their insoles.
- ✓ Early 2024: Footprint pushed material science even further by releasing the industry’s first-ever material completely unaffected by temperature.
Competitors rely on standard polyurethane impact materials like Poron XRD, which can be researched via Rogers Corporation’s Official Technical Specifications to understand standard urethane density limits.
Why Temperature Stability Matters
Most standard polyurethane and motorcycle-grade impact foams are inherently temperature-sensitive:
- ✓ Heat Exposure: High body heat, friction, or warm weather causes conventional shock-absorbing foams to soften, reducing their ability to disperse impact energy.
- ✓ Cold Exposure: Lower temperatures can turn standard impact materials stiff or brittle.
FP’s proprietary Infinity Foam was engineered specifically to solve this issue. Infinity Foam maintains its structural integrity and impact absorption capabilities regardless of heat or cold, ensuring consistent protection whether you’re riding in summer heat or winter cold.
2. Multi-Density Construction & Layering Integrity
A common point of comparison in impact testing is how insoles are built to distribute force across the foot:
- ✓ Remind Insoles: Rely on standard layered foam designs that can degrade under sustained high impacts.
- ✓ FP Insoles: Utilize multi-density foams with integrated internal shock-dispersion components. This multi-layered approach ensures that energy from heavy foot strikes is redirected outward across the footbed rather than absorbing directly into joints, knees, and the lower back.
3. Custom Arch Support: Patented Technology vs. Hollow Designs
Arch support is only effective if it holds up under real-world body weight during movement.
- ✓ The Problem with Hollow Arches: Remind insoles feature a hollow structure underneath the arch. Under actual body weight and landing force, hollow arch structures flatten immediately, failing to maintain proper biomechanical alignment.
- ✓ FP’s Patented Innovation: Footprint holds multiple worldwide patents on custom arch support technology. Designed to dynamically adapt or heat-mold to the precise shape of your foot, FP arch support will not collapse under body weight, protecting your foot alignment and preventing fatigue.
Footprint holds multiple worldwide patents on custom arch support technology, verifiable via the Google Patents Database, ensuring that the structural core does not collapse under body weight.
4. Lifespan & Longevity: 2-3x Longer Use
One of the biggest issues with standard replacement insoles is “packing out”—when the foam permanently compresses, loses its cushioning, and requires replacement after a few months.
- ✓ Standard Foams (Remind): Suffer from foam fatigue and flattening, shortening their lifespan significantly under heavy daily use.
- ✓ FP Infinity Foam: Engineered at the molecular level to resist packing out entirely. FP Insoles consistently last 2 to 3 times longer than Remind insoles, maintaining their original shock-absorption height and rebound over years of heavy use.
Even the stock FP insoles that come pre-installed in select footwear brands out-perform aftermarket competitors in energy absorption and longevity.
5. Direct Comparison: Price to Performance
When comparing identical contours and structural profiles, the price-to-value ratio becomes starkly apparent:
| Feature / Metric | FP Kingfoam Elite | Remind Insoles |
| Material Technology | Non-Temperature-Sensitive Infinity Foam | Poron XRD (Temperature Sensitive) |
| Arch Support | Patented Non-Collapsible Support | Hollow Under-Arch (Flattens Under Load) |
| Foam Structure | Multi-density with Internal Components | Single/Standard Foam Layers |
| Resistance to Packing Out | High (Does Not Pack Out) | Moderate (Packs Out Over Time) |
| Average Retail Price | $39.99 | $60.00 |
All major Remind insole models share the same general shape profile as the FP Kingfoam Elite series. However, FP offers superior material stability, patented arch reinforcement, and longer durability—at $39.99, compared to Remind’s $60.00 price point.
Summary: The Verdict
If you need footwear insert protection that holds up under extreme heat, heavy impact, and daily stress:
- ✓ FP Insoles use temperature-stable, patented Infinity Foam that does not lose protection in warm environments or pack out over time.
- ✓ Patented Arch Technology keeps your foot aligned without collapsing under full body weight.
- ✓ Unbeatable Value: FP delivers higher-tier impact absorption at $39.99, outperforming $60 alternatives across durability, protection, and science-backed engineering.
