Action Sports Insoles: 25J Impact Test Comparison
Comparing Reported Impact-Test Results for Action-Sports Insoles
This report compares published action-sports insole impact-test results, including FP Insoles, Remind, Amazon-brand insoles, and Z-Liner products. The test content shown on this page focuses on transmitted-force behavior under stated impact-test conditions.
Lower transmitted-force readings indicate that less peak force passed through the test setup during the reported impact test. These results should be considered alongside footwear fit, skating style, landing intensity, support needs, material firmness, comfort, and individual preference.
The findings apply only to the tested products and conditions shown in this report. They do not independently prove pain relief, injury prevention, faster recovery, joint protection, or long-term medical outcomes.

This report summarizes published action-sports impact-test observations involving FP Insoles, Remind, Amazon-brand insoles, and Z-Liner products. The findings apply only to the tested samples and shown conditions and should be considered alongside footwear fit, skating style, landing pattern, support needs, material firmness, and individual comfort.
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 →What the 25J Impact Test Shows
This report uses published 25-joule impact-test content to compare how selected action-sports insoles responded under the stated testing conditions.
25 Joules (25J) refers to the amount of impact energy applied during the test. The results are used to compare transmitted-force behavior between the tested products.
A lower transmitted-force result suggests that less peak force passed through the tested insole and measurement setup during this specific test. However, this test does not directly measure skating performance, pain relief, bruising risk, injury prevention, recovery time, or long-term joint health.
Reported FP Insoles Results
Here’s what the impact test revealed:
- FP Kingfoam Orthotics FluidX Hi: Reported as one of the lower transmitted-force results in the shown action-sports impact test.
- FP Kingfoam Elite models: Reported as lower transmitted-force options among the tested products.
- FP Gamechanger models: Reported as lower transmitted-force options in the shown comparison.
Based on the reported impact-test content shown on this page, FP Insoles recorded lower transmitted-force results than the compared Remind, Amazon-brand, and Z-Liner options. This finding applies only to the tested samples and stated conditions.
Higher Transmitted-Force Results: Remind, Amazon Brands, and Z-Liner
In the shown comparison, Remind, Amazon-brand insoles, and Z-Liner products recorded higher transmitted-force readings than the tested FP Insoles options.
Higher transmitted-force readings mean that more peak force passed through the test setup under the stated conditions. This does not automatically mean the products are unsuitable for every user, but it may matter for users prioritizing measured impact attenuation.
Below is a detailed comparison of the reported FP Insoles and Remind test results.
How to Interpret kN and Transmitted Force
kN stands for kilonewtons. It is a unit used to express force. In this report, kN values are used to describe the reported transmitted-force readings from the impact-test setup.
Lower kN reading: Less peak force passed through the tested insole and measurement setup under the stated conditions.
Higher kN reading: More peak force passed through the tested insole and measurement setup under the stated conditions.
These readings can help compare impact attenuation between tested products. However, kN readings do not directly measure how much force a specific person’s foot, joints, or body experiences during real-world skating or action-sports activity.
Product selection should also consider shoe fit, skating style, landing pattern, cushioning preference, insole thickness, arch support, durability, and personal comfort.
Remind Insoles: Reported Test Observations
A common question is whether Remind insoles perform consistently under repeated or warmed testing conditions.
Here’s the truth:
The test content shown on this page suggests that the tested Remind sample may have been sensitive to warming and repeated impact conditions. However, this should be described as a reported observation from the shown test, not as a claim about every Remind product.
The available page content does not independently establish long-term durability, real-world comfort, injury risk, or performance across all Remind models.
Temperature-Sensitivity Observation
In the shown test content, the tested Remind sample appeared to change behavior after warming. This may be relevant for users comparing material response, but more controlled testing would be needed to confirm how consistently this occurs across models, sizes, and real-world use.
Material-Use Context
The page references Remind’s material background, but this report should avoid assuming that the material is unsuitable for all footwear use unless supported by verified documentation or separate material testing.
Material suitability depends on product design, intended use, footwear fit, activity type, and how the material performs under repeated conditions.
User feedback may provide useful context, but it should be separated from controlled laboratory data unless review sources, sample size, and collection method are clearly documented.
Simple Explanation of Transmitted Force
In simple terms, transmitted force describes how much peak force passed through the tested insole and measurement setup during the impact test.
- Lower transmitted-force reading: Less peak force passed through the test setup under the stated conditions.
- Higher transmitted-force reading: More peak force passed through the test setup under the stated conditions.
These readings are useful for comparing impact attenuation between tested products. However, they do not directly show how much force a specific user’s foot, heel, joints, or body experiences during skating, jumping, landing, or daily movement.
Real-world results may vary based on footwear, body weight, landing style, skating surface, activity intensity, insole fit, and individual comfort needs.
Conclusion: What the Impact-Test Results Show
Based on the reported action-sports impact-test content shown on this page, the tested FP Insoles options recorded lower transmitted-force readings than the compared Remind, Amazon-brand, and Z-Liner options.
Under the stated test conditions, this means less peak force passed through the FP Insoles samples and measurement setup. This may be relevant for users who prioritize measured impact attenuation when choosing insoles for action-sports footwear.
Remind, Amazon-brand, or Z-Liner products may still suit users who prefer their fit, feel, thickness, price point, or footwear compatibility. A higher transmitted-force reading does not automatically mean a product is unsuitable for every user or every situation.
These findings apply only to the tested samples and shown test conditions. They do not prove pain relief, injury prevention, faster recovery, reduced bruising, improved skating performance, or long-term joint protection.
| Comparison Area | Finding |
|---|---|
| Lowest transmitted-force readings shown | FP Insoles |
