My only problem with the alignment/balance issue is that it can be skeletal or muscular.
If it’s a muscular problem, the issue might be corrected by exercises: strength, yoga, etc. A knee problem might actually be caused by a hip flexor issue. Stretching
might help with poor dorsiflexion and strengthening hip flexors
might help with the lower leg angle. I’m emphasizing “might” because I realize it’s not gospel and I do not intend to negate anything in
@bud heishman ’s very informative post. I’m just interested in what experienced bootfitters think about this.
I agree with
@Philpug instructors should learn to somehow identify equipment problems. However,
how to solve that problem should be left to an experienced fitter. I’ve had well-meaning instructors in the past try to help solve an equipment problem I had, and they unwittingly made the problem worse.
