What can happen if an orthotic is recommended and I never get one?
The orthotics that your doctor uses correct and restores normal alignment and function which almost always results in better alignment and factually speaking - better alignment means greater comfort! Often our doctors relay to us that their patients say that the realignment of their feet leads to less ankle, knee, hip, and low back pain in addition to addressing the heel or arch pain that they came to the doctor to get handled.
The point is that not restoring proper alignment can lead to further problems in the future, not just in your feet, but higher up in the various joints and muscles of your entire body. If an orthotic can help prevent these things as your doctor has advised, then you simply run the risk of developing problems in the future if you ultimately decide not to get them.
