Product Short Summary:

  • Thickness: 6mm toe to 8mm heel
  • Dual density non newtonian arch chamber custom forms to your arch within minutes of wearing.
  • TPU layer under fabric for advanced durability
  • Absorbs more than 90% of shock energy in astm f1614 lab tests and 2-3 times more than any competitor
  • Same formula we used to make custom parts for NASA
  • Cuts daily fatigue dramatically — average insoles transfer 12,000 - 25,000+ N of shock into the body per step.
    • Kingfoam Elite Quantum Heel transfers only ~3000 - 5000 N.
    • Multiply that by 10,000 steps a day and the difference is massive.

10,000 Steps Means Thousands of Impact Events

Every step creates force beneath the feet. Over a full day of walking, working or training, those repeated impacts can add up.

Kingfoam Elite Quantum Heel uses Infinity Foam cushioning beneath the heel and forefoot to help manage repeated force, while the Quantum Heel structure provides additional support around the heel.

Who Kingfoam Elite quantum heel is For

Kingfoam Elite Quantum Heel is designed for users who want strong cushioning with more structured heel support.

It is suited for people who:

  • Want more heel support than a flat insole
  • Experience repeated heel impact
  • Walk or stand for long periods
  • Work on hard surfaces
  • Run or train regularly
  • Skate or participate in action sports
  • Want a more secure heel position
  • Prefer heat-moldable heel support
  • Want Infinity Foam cushioning without a full custom-arch structure

For both custom arch support and Quantum Heel support, compare Gamechangers Pro.

Why normal insoles Fail?.

Standard stock insoles are often flat and provide limited support around the heel. Under repeated impact, conventional cushioning can also compress and lose performance.

This can leave the heel less supported during:

  • Walking
  • Running
  • Training
  • Long work shifts
  • Repeated landings
  • High-impact movement

Kingfoam Elite Quantum Heel adds both impact cushioning and a structure that forms more closely around the heel.

Why FP is Different?

Kingfoam Elite Quantum Heel combines two technologies with different jobs:

  • Infinity Foam helps cushion repeated impact beneath the heel and forefoot.
  • Quantum Heel provides heat-moldable support around the heel.

Together, they provide cushioning plus a more personalized and stable heel fit than a standard flat stock insole.

How Quantum Heel Heat Molding Works

Before molding, the Quantum Heel structure maintains its original shape.

When heated according to FP’s product instructions, the heel structure becomes more responsive. As the insole cools around your foot and shoe, it forms more closely around the heel.

After molding, it helps provide:

  • A more secure heel position
  • Personalized heel contact
  • Better in-shoe stability
  • More consistent support
  • A fit shaped around your footwear

Heat Molding Instructions

  1. Trim the insole to fit your shoe if needed.
  2. Follow FP’s product-specific heating time and temperature instructions.
  3. Place the warmed insoles flat inside your shoes.
  4. Put on the socks you normally wear.
  5. Position your feet naturally in the shoes.
  6. Allow the Quantum Heel structure to form and cool around your heel.
  7. Check both insoles for a comfortable and even fit.

Quantum Heel Performance and Impact Testing

FP tests its cushioning materials under controlled conditions to compare shock absorption and repeated-impact performance.

    Preheat your oven to 250°F (120°C).
  3. Heat Insoles:
    Place insoles flat on a baking sheet.
    Heat for 12 minutes.

  5. Mold to Your Foot:
    Place the insoles into your shoes while wearing socks.
    Stand and walk naturally until the insoles fully cool down.

Important:

  • Do NOT fold or bend the insole while hot. This can permanently damage the structure.
