FP Kingfoam Flat 7mm Burman Tea Party Insoles

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

Specs:

• Simple stock insole replacements
• Trimmable- if your size is out, get one size up and trim with scissors.
• Absorbs 91% of impact energy in lab testing compared to 53% in other “performance” insoles (ASTM F 1614 -1999)
• Actually works in the shoe at body temperature
• Cuts daily fatigue dramatically — average insoles transfer 12,000 - 25,000+ Nof shock into the body per step.
  • King Foam transfers only ~3000 - 5000 N.
  • Multiply that by 10,000 steps a day and the difference is massive.
