I have a relatively minor (6mm) leg length discrepancy due to scoliosis. For decades I suffered with low back pain that may have been relieved temporarily following chiropractic adjustments but became increasingly more painful and incapacitating. A new chiropractor diagnosed my leg length discrepancy and found American Heelers for me. They have added lifts to everything from flip flops to work shoes for me and the results have been incredible. My pain is gone, the mobility is almost completely back to normal is less than a few months. Their artistry in adding the lift to each type of shoe is incredible, and the ease and speed of each transaction I have had with them has been fantastic. I highly, highly recommend them!
