FP INSOLES KING FOAM ORTHOTICS INFINITY FOAM
- Extreme impact protection and durability
- Thickness: 6mm toe to 8mm heel
- Dual density arch chamber featuring our patent pending construction method dynamically adapts to each step.
- TPU layer under fabric for extreme durability
- Absorbs more than 90% of shock energy in astm f1614 lab tests
- Same formula we use for NASA
- Break in period : 3-5 days
- Trim width if too wide for shoes
-
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.
