What do foot orthotics actually do?
Prescription foot orthoses (commonly called “orthotics”) are precision medical devices that adjust and control the function of the foot and it’s alignment with the lower leg. They are used to treat/prevent injury causing motions like excessive pronation (collapsing in) and supination (rolling out) and make standing, walking and running more effective. Some orthotics are designed to redistribute pressures on the bottom of your foot to alleviate pain from corns, calluses and bony prominences.
