Description
Welcome to a new level of cushioning. Kingfoam Super Squish combines FP’s impact-focused Kingfoam construction with a full-length Super Squish Gel bottom layer for an insanely soft, cloud-like feel underfoot.
The result is more comfort, more cushion, and dependable support for walking, skating, training, work, and everyday wear. Unlike ordinary foam insoles that can quickly feel flat once they warm up, Super Squish Gel keeps delivering that plush, responsive ride throughout the day.

Total squish without sacrificing performance
King Foam: Anatomy of Performance
King Foam uses a simple flat construction focused on cushioning rather than structured arch support.
Infinity Foam helps manage repeated force beneath the heel and forefoot while allowing the insole to work naturally across different foot shapes.
Main Components
- Infinity Foam cushioning
- Flat footbed design
- Cushioned heel
- Cushioned forefoot
- Flexible construction
- Trim-to-fit shape
10,000 Steps Means Thousands of Impact Events
Every step creates force beneath the feet. Walking, running, working and training can expose your feet to thousands of repeated impact events throughout the day.
King Foam uses Infinity Foam cushioning to help absorb that repeated force beneath the heel and forefoot before more of it travels through the body.
Infinity Foam That Absorbs Repeated Impact
Standard foam can compress and lose cushioning during repeated use.
King Foam uses FP Infinity Foam to help absorb impact while maintaining cushioning through repeated compression.
Built for Repeated Movement
- Cushions heel impact
- Cushions the forefoot
- Handles repeated compression
- Designed for long periods on your feet
- Works without rigid arch support
- Suitable for daily and athletic footwear
- Soft insoles feel good at first
- Foam flattens quickly
- Comfort disappears with daily use
FP Absorbs 90% of Shock Energy
Compared to 53% in other Performance Insoles
NASA supplier. Our proprietary material is used for shock absorption on the International Space Station.
Designed for Daily Use & Active Lifestyles
King Foam provides straightforward cushioning for a wide range of daily and athletic activities.
Designed for:
- Walking
- Standing
- Physical work
- Gym training
- Running
- Skateboarding
- Action sports
- Everyday footwear
The flat construction allows users to add Infinity Foam cushioning without changing to a structured custom-arch insole.
Flat Cushioning That Works Across Foot Shapes
King Foam does not force the foot against a fixed arch structure. Its flat cushioning design works across different foot shapes while providing impact protection beneath the heel and forefoot.
It can also suit users with higher arches who prefer cushioning without aggressive built-in arch support.
King Foam Performance and Impact Testing
FP tests its cushioning materials under controlled impact conditions to compare shock absorption and repeated-impact performance.
