How They’re Made
Custom orthotics are made up of a rigid yet slightly flexible foundation, such as polypropylene or graphite as well as a cushioned casing for comfort, usually neoprene, silicone, or ethylene-vinyl acetate. The plastic core is shaped to correct your feet’s specific musculoskeletal imbalances and to redistribute pressure when you’re standing and moving in order to encourage proper arch, joint, and bone alignment.
Depending on what your orthotics are made of, they may last you anywhere from 5 to 10 years through the top cover on the shell may need replacing sooner because of wear and tear. But don’t worry; it’s a quick and affordable process.
