Replying to Boot fitting for birth defects

This is a question for boot fitters or anyone who has any experience with something like this. I was born with positional club foot on my right foot, this caused my right leg to be substantially smaller than my left as well as my right foot is pretty much locked into place with a little bit of y-axis movement. I have always just had my boot fitted for my normal foot/leg and dealt with the pain in the other. Does anyone have a solution or experience with something like this? I'd love to hear some suggestions for the best option.
