Actual Performance metrics
The Data Doesn’t Lie but other insole brands do
It’s a scientific fact that FP asorbs 2-3 times more force than any insole, with every step, thousands of times per day.
Every brand says their insoles are shock absorbing… and some even make faked impact test videos but only FP actually absorbs the most shock and transfers the least force—at every impact level.

FLUIDX Facts
Is there a break in period?
Yes, during the first few days the foam cells in the insoles that encases the fluidx will break in to fit to your foot even better. The insoles also activate in the first 5-10 minutes of wearing and adapt to your foot.
Do I need to trim the insoles?
If you wear very narrow shoes you will need to trim the arch on each side about 3mm so that the insole fits properly in the shoe.
Will FP Insoles slow me down?
FP Insoles will not slow you down and we guarantee it. We also guarantee you’ll be able to run or play any sport longer. They only absorb the residual shock energy that happens above the outsole and the ground where the impact occurs. This protects your body from fatigue. FP Insoles are also non newtonian. This means they actually get firm on impact which is the opposite of mud or sand. They adapt to different types of activity, such as walking, running, and jumping depending on the level of impact. For example, when you run they become more stiff on each impact which helps you propel forward compared to normal insoles that squish down but when you stand or walk , FP Insoles are more soft and cushioning.
How long do they last?
Fp Insoles will last years. Olympian skateboarder Micky Papa jumps down stairs everyday and after 4 months of taking a daily beating, his FP Insoles beat brand new insoles from any competitor.

Marco B –
My new snowboard boots came with reasonable insoles. Not to bad but not as good as the aftermarket insoles In my old boots.
So I went to a local skate/snowboard shop.
They suggested the fluidx…. They couldn’t deliver my size so I bought them online.
Sizing and fit are perfect, very supportive and super cushioning. Never want other insoles again!
Next ones I buy in the store again!
