FP Insoles Kingfoam Orthotic Fluidx2
$49.99 – $59.99Price range: $49.99 through $59.99
- FluidX² — upgraded dynamic comfort using non-Newtonian impact technology.
- Not recommended for pancake-flat feet — FluidX is designed for neutral to mid-arch feet that benefit from adaptive movement, not rigid arch correction.
- The world’s most shock-absorbing insole — unique design with patent-pending technology.
- Cuts daily fatigue dramatically — average insoles transfer 6,000–12,000+ kN of shock into the body per step.
- FluidX transfers only ~2,800–3,000 kN.
- Multiply that by 10,000 steps a day and the difference is massive.
- Mid Profile includes Heel Saviors for added impact protection and comfort.
- High Profile designed for sports and action sports.
- Mid Profile designed for walking and moderate sports.
- Low Profile designed for dress shoes and low-volume footwear.
Description
Your Arch Moves.
Now Your Support Moves With It.
Meet FluidX2 Orthotic Technology
Inside: FluidX Dynamic Arch Core

At the heart of every Kingfoam Orthotics FluidX insole is a 
non-Newtonian arch chamber.

What does that mean?

- Soft and comfortable at rest
- Firms up instantly under pressure
- Returns to neutral when pressure is removed

So instead of static support, you get responsive support.

- Comfort when standing.
- Structure when moving.
- Stability when landing.
- No heat required.
- No rigid plastic digging into your arch.
- No guesswork.
- Just intelligent support.
Most Insoles Stay The Same.. Your Foot Doesn’t.
Your arch changes shape when you:


- Walk
- Run
- Stand
- Land
- Shift weight

Traditional foam insoles collapse:
- 
Rigid inserts stay hard.
- Neither adapts to movement.
- That’s why your feet still feel fatigued
FluidX reacts instead of resisting.
