Who needs Heel Lifts?

If you suspect you have one leg that is physically shorter than the other,  heel lifts may be appropriate, but first, you should see a medical provider who can document with certainty that you actually have a physical leg length discrepancy (typically established by x-ray images). 

Sometimes what appears to be a physical leg length difference can actually be adjusted out by osteopathic or chiropractic manipulation, or by balancing muscles through soft tissue therapy. 

If you have already been diagnosed with a physical leg length discrepancy, the difference in length determines how to compensate for it.  If the leg length difference requires less than 6-8mm compensation, inserting heel lifts inside the shoes may work well.  If you insert a higher heel lift,  the shoe may become uncomfortable.  Usually, if the leg length discrepancy requires more more than 6-8mm compensation, it is better to have your shoe repair shop build up the full length of the entire outsole.  You may want to see a Pedorthist who specializes in building shoes for people with difficult to manage lower extremity and foot problems. 

Drifting to one side when you walk may not be because of a physical leg length discrepancy. 

Most people who hyperpronate have a functional leg length discrepancy.  One ankle collapsing slightly more than the other creates this functional difference.  Leg length discrepancies, both physical and functional contribute to pelvic instability and scoliosis (abnormal lateral curves of the spine).  Posture Control Insoles(TM) will help balance out functional leg length discrepancies. 

Some people feel tension in one or both Achilles tendons when they wear flat shoes.  Using a small amount of heel lift in both shoes (symmetrical) will help relieve this sensation.
