Superfeet vs FP Insoles: 10J Impact Test Comparison
Comparing Reported Transmitted-Force Results Under 10J Impact Testing
This report compares published 10J impact-test results for three Superfeet models and several FP Insoles models. The test records the peak force transmitted through each insole under the stated laboratory conditions.
The reported Superfeet readings ranged from 16,000 N to 27,000 N, while the listed FP Insoles models recorded between 3,000 N and 6,000 N. Under these specific conditions, the tested FP models allowed less peak force to pass through the measurement setup.
These results apply only to the tested products and conditions presented in this report. They do not independently establish comfort, durability, pain relief, injury prevention, improved biomechanics, or long-term health outcomes.
Below is a detailed comparison of the reported Superfeet and FP Insoles test results.

This report summarizes published transmitted-force results from a 10J impact comparison involving selected Superfeet and FP Insoles models. The findings apply only to the tested samples and stated conditions and should be considered alongside fit, support, footwear compatibility, activity, and individual comfort needs.
Part of the InsoleWars Lab Reports Series
This report is one of several InsoleWars impact-test comparison pages covering reported 5J, 10J, and 25J transmitted-force results.
View all Insole Lab Reports →Why Transmitted-Force Testing Matters
During a controlled impact test, part of the applied energy may be absorbed or dispersed by the insole, while the remaining force passes through the test setup. Measuring the peak transmitted force provides a consistent way to compare different insole samples under the same laboratory conditions.
A lower transmitted-force reading indicates that less peak force passed through the measurement setup during that specific test. This can help compare impact-attenuation performance, but it does not directly measure forces inside the feet, ankles, knees, hips, or spine.
Laboratory impact data should be considered alongside arch support, heel stability, material firmness, footwear compatibility, activity level, fit, and individual comfort preferences.
Testing Methodology
This comparison uses reported 10-joule impact-test results. During the test, a controlled amount of impact energy was applied to each insole sample, and the measurement system recorded the peak force transmitted through the sample in Newtons.
10 Joules (10J): The amount of impact energy applied during the test.
Newtons (N): The unit used to report the peak transmitted-force reading.
For a fair comparison, products should be tested using the same equipment, impact level, sensor arrangement, sample preparation, and measurement procedure.
The available results support a comparison of transmitted-force readings under the stated laboratory conditions. They should not automatically be treated as a direct simulation of walking, standing, running, or other real-world activities unless that relationship is confirmed in the original test documentation.
How to Interpret Newton Values?
Newtons are used here to report the peak force transmitted through each insole sample during the controlled 10J impact test.
Higher transmitted-force reading
- More peak force passed through the tested insole and measurement setup.
- Indicates lower impact attenuation within this specific laboratory comparison.
Lower transmitted-force reading
- Less peak force passed through the tested insole and measurement setup.
- Indicates stronger impact attenuation within this specific laboratory comparison.
Transmitted-force readings can help compare how the tested samples responded under identical conditions. However, these values do not directly measure pressure inside the foot, forces within the joints, pain reduction, fatigue, injury risk, or long-term musculoskeletal health.
Transmitted-force testing is one useful measurement for comparing impact attenuation, but it should be considered alongside fit, arch support, heel stability, footwear compatibility, material firmness, activity, and individual comfort.
Laboratory Results
Superfeet Performance Data
FP Insoles Performance Data
Comparison of the Reported Results
Under the reported 10J test conditions, the three Superfeet models recorded peak transmitted-force readings between 16,000 N and 27,000 N:
- Superfeet Green: 16,000 N
- Superfeet Orange: 17,000 N
- Superfeet Run: 27,000 N
The listed FP Insoles models recorded readings between 3,000 N and 6,000 N.
Depending on which models are compared, the FP Insoles readings were approximately 63% to 89% lower than the Superfeet readings. Under these specific laboratory conditions, the tested FP models allowed less peak force to pass through the measurement setup.
This range comparison does not mean that every FP model performed by the same percentage against every Superfeet model. Each product should be compared using its individual recorded value.
These results describe transmitted-force performance only. They do not independently prove reduced joint loading, pain relief, injury prevention, improved endurance, or clinically meaningful health benefits.
Practical Meaning and Test Limitations
What the results show
- The tested FP Insoles models recorded lower peak transmitted-force readings than the tested Superfeet models.
- Under the stated 10J conditions, less peak force passed through the FP Insoles samples and measurement setup.
- These findings may be relevant for users who prioritize measured impact attenuation when comparing insoles.
- The results provide a controlled laboratory comparison between the specific models tested.
What the results do not establish
- Reduced pressure at the heel, arch, or forefoot
- Improved balance or proprioceptive feedback
- Delayed fatigue or better endurance
- Prevention of stress fractures, plantar fasciitis, or tendinopathy
- Reduced joint degeneration or long-term joint preservation
- Guaranteed comfort, pain relief, or injury prevention
Real-world performance may vary according to footwear, fit, activity, body weight, movement pattern, foot structure, and individual support preferences. Separate pressure-mapping, durability, comfort, or clinical testing would be required to support broader health and performance claims.
Product Design Context
Tested Superfeet Models
The reported comparison includes:
- Superfeet Green: 16,000 N
- Superfeet Orange: 17,000 N
- Superfeet Run: 27,000 N
These readings show how the tested Superfeet samples performed in the 10J transmitted-force comparison. The test does not determine whether their support shape, material firmness, arch profile, or overall fit is suitable for a particular user.
Tested FP Insoles Models
The listed FP Insoles models recorded transmitted-force readings between 3,000 N and 6,000 N.
These readings indicate lower peak transmitted force under the stated test conditions. However, this test does not independently prove heat adaptation, customized fit, pressure redistribution, durability, or long-term comfort.
Important Product-Comparison Context
- Transmitted-force performance is only one part of insole selection.
- A lower reading does not automatically make one product superior in every category.
- Users may prefer different levels of arch structure, cushioning, flexibility, heel stability, and shoe compatibility.
- Product-material and design claims should be supported by separate testing or clearly attributed manufacturer documentation.
- The most suitable insole depends on the user’s footwear, activity, foot structure, support preferences, and comfort.
Comfort, Fit, and User Preference
Superfeet Considerations
Superfeet models may appeal to users who prefer:
- A firmer or more structured feel
- Defined arch support
- A stable heel platform
- A support shape compatible with their footwear and foot structure
FP Insoles Considerations
FP Insoles models may appeal to users who prioritize:
- Lower transmitted-force readings in this 10J comparison
- A choice between several tested models
- Cushioning and impact attenuation as part of their selection
- Compatibility with their footwear, activity, and preferred support level
Important Comfort Note
The displayed laboratory test did not directly measure comfort, pressure distribution, break-in time, heat molding, fatigue, or extended-wear experience. Comfort is subjective and may vary according to shoe fit, foot shape, activity, body weight, material firmness, and personal preference.

Test Limitations
- The findings apply only to the specific models and samples tested.
- The 10J test measures peak transmitted force, not overall insole quality.
- It does not directly measure comfort, pressure distribution, arch-support effectiveness, durability, fatigue, pain relief, or injury prevention.
- Results from Superfeet Green, Orange, or Run should not automatically be applied to every Superfeet product.
- Results from the listed FP models should not automatically be applied to every FP Insoles product.
- Real-world performance may vary according to footwear, activity, foot structure, movement, body weight, fit, and personal preference.
- Separate testing would be required to evaluate repeated compression, heat response, durability, pressure distribution, and long-term performance.

Conclusion: What the 10J Results Show
In the reported 10J impact comparison, the tested Superfeet models recorded peak transmitted-force readings between 16,000 N and 27,000 N. The listed FP Insoles models recorded readings between 3,000 N and 6,000 N.
Under these specific laboratory conditions, the tested FP Insoles models allowed less peak force to pass through the measurement setup. Based on this measurement, FP Insoles may be the stronger option for users who prioritize transmitted-force reduction as part of their insole selection.
Superfeet may still suit users who prefer the fit, firmness, arch profile, or structured feel of a particular Superfeet model. A higher transmitted-force result does not establish that a product is unsuitable in every category or for every user.
The most appropriate insole depends on footwear compatibility, activity, foot structure, support needs, cushioning preference, and individual comfort.
