Corefit® Heat Moldable Custom Insoles have been handcrafted in the USA since 1932, bridging the gap between podiatrist prescribed custom insoles and flimsy store bought rubber, gel and foam insoles. Most mass produced insoles are fabricated from simple cellular sponge and/or foam rubber materials. These products may provide some shock absorption, but minimal (if any) therapeutic control or plantar fasciitis support. Corefit® Custom Insoles can be personalized to fit any individual foot in just seconds, by simply dipping them in hot water and custom fitting to the foot. They soften with moderate heating, allowing fitting to the foot, before cooling to their original, rigid state. Our medical grade custom insoles help prevent heel spur, heel roll, provide support to high arches and promote better posture while providing proper weight distribution & relief from plantar fasciitis.


Not Gel. Not Foam. Just Effective. ®

The foot forms the core foundation of the body. Its 52 bones, 66 joints, 214 ligaments and 38 muscles carry us through our daily lives in an often unnoticeable and unappreciated way. Podiatrists typically prescribe custom moldable insoles to address foot ailments which cause foot soreness. Custom insoles for plantar fasciitis or heel spur are orthopedic devices which are custom fitted (often at considerable cost) to correct or adjust abnormal foot motion; they provide foot support, stability and control. The stability and efficiency of the foot, arch and ankle promote better foot health and overall body function. Corefit® Custom Moldable Plantar Fasciitis & Heel Spur Insoles provide this same balance of stability and comfort at an affordable cost.

Each pair of Corefit® Custom Insoles is handcrafted entirely in the USA.


Corefit® Custom Moldable Insoles provide firm, effective foot comfort by simplifying the custom fitting process:

  • Immerse our plantar fasciitis inserts in boiling water for 30 to 45 seconds (Never place inserts inside a microwave)
  • Remove from water with tongs, grasping the front of insole only.
  • In a seated position, with a sock on foot, place the warm insert in position beneath your foot. Then, using your fingers and the heel of your hand, mold the insert to the contours of the foot, paying particular attention to the longitudinal and metatarsal arch areas.
  • When the insert has cooled to room temperature, it is then ready to be placed in your shoe and worn.
  • If the insert becomes uncomfortable, dip only the troublesome portion in boiling water and repeat manipulation by hand.
  • When reheated, your custom insole will return to its original shape and can be remolded.
