RELIEVE LOWER BACK, KNEE & FOOT PAIN. Our firm, podiatrist grade orthotic shoe inserts have been supplied to podiatrists since 1932 to help correct and relieve the pain & pronation associated with PLANTAR FASCIITIS, HEEL SPUR, HIGH & FLAT ARCH ailments. Our ability to walk pain-free is vital to quality of life. When flat feet overpronate, high arches supinate or standard shoes don’t offer adequate support, the tendons & ligaments of the foot can become fatigued and fail. This can create a “domino-effect” of pain, radiating from your feet to your knees, hips and even the lower back.

Corefit®Self Moldable Shoe Inserts  have been handcrafted in the USA since 1932. We bridge the gap between podiatrist prescribed custom made shoe inserts and flimsy store bought rubber, gel and foam insoles. Corefit Inserts can be personalized to fit any individual foot in just seconds, by simply dipping them in hot water and custom fitting to the foot. Our firm arch supports soften when dipped in boiling water, allowing molded fitting to the foot before cooling to their original, rigid state, ready for insertion into your shoes.

Corefit® Custom Shoe Inserts are handcrafted in the USA.

Our Simplified Fitting Process:


  • Immerse our self moldable inserts in boiling water for 90 seconds (Never place inserts inside a microwave or oven)
  • Remove from water with tongs, grasping the front of insert only.
  • From a seated position with legs crossed (and socks on) use a towel or cloth to place the warm insert in position beneath each foot while in the air. (Our product is most effective when fitted to a non weight bearing foot.) Using your fingers and the heel of your hand, mold each individual insert to the contours of your 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 insoles will return to their original shape and can be remolded.
