The ultimate stock insole replacement, Kingfoam Insoles are designed to bring superior comfort and performance to every step you take. Ideally suited for mid to high arches, these insoles provide cloud-like softness and optimal shock absorption.

Benefits of Kingfoam Insoles

  • Arch Compatibility: Best for mid to high arches.
  • Thickness Options: Available in 3mm, 5mm and 7mm thicknesses.
  • Premium Material: Crafted from military-grade UHD memory foam for ultimate softness and moisture wicking.
  • Outstanding Shock Absorption: Laboratory testing shows that our insoles absorb over 90% of shock energy — significantly higher than the 53% recorded for other "performance" insoles (ASTM F 1614-1999).
  • Sizes: Available in multiple sizes. Select your exact size or one larger and simply trim to fit.

*Note: For women's insole sizing, add 2 sizes up. (Ex: a men's size 4 insole is a women's size 6.) View full details

Kingfoam Insoles: Advanced Comfort for Mid to High Arches

Our Kingfoam Insoles are an easy and effective upgrade to your existing stock insoles. Suitable for all foot types but especially beneficial for mid to high arches, they can be used in shoes originally equipped with 4-6mm thick stock insoles. Simply remove your old insoles, insert our Kingfoam Insoles, and, if needed, trim for a perfect fit. 

Step Into Space-Age Support

When you step into our insoles, you're stepping into the same material used aboard the International Space Station (ISS). After rigorous testing, NASA selected our proprietary FluidX material to protect their Astrobee robots’ highly sensitive equipment, prioritizing its lightweight and high energy-absorbing properties. 

Special injection-molded components, created in the same manner as our elite series insoles, were integrated into the existing parts of the Astrobee. Now, this cutting-edge material that passes NASA's stringent standards is at your feet, providing unparalleled comfort and support with our Kingfoam Insoles.
