If you are wearing the heel insert you were given, you might want to look into that too. I was told that leg discrepancy is not always truly bone related and mostly superficial. It is different, for most people, from day to day since it is mostly related with muscle tightness ( if you sit , sleep weird ... ) For example, the discrepancy before and after a massage is mostly different, sometimes significantly. After few experiences, I am skeptical of inserts in general.
