I am a bus driver who is hoping to locate a source of very tall heeled work shoes or boots (about 3-4" oversize heels, ideally with a rounded "rocker" heel to give comfort for using gas/brake pedal all day). I am hoping to end discomfort in right (driving) leg which is some numbness in sole of foot and discomfort from pressure of right thigh (possibly due to contact of right (driving) leg on hard bus seat all day.
I think the pressure of the thigh on the right driving leg caused by the hard seat is crimping the blood flow in that leg and causing the numbness in the right sole of the foot. The idea is by using a 3-4" heel on the driving shoe/boot, it lifts my thigh just off the hard bus seat and gives an air gap which hopefully will stop that crimped blood flow, which I think is causing the numbness in sole.
I drive disabled clients and noticed some wear such footwear that has a noticeably higher and larger heel (and looks rugged too), they look like what might be called "monster mash" boots LOL as they are so big they stand out. Not sure what these are called but look like they might work for my problem. Perhaps these are used by diabetics or other medical conditions?
The point is, no one on this forum is in a position to do anything but guess; see your doctor as soon as you can with a good solid list of your symptoms, how often they occur, when they occur, and what you are doing when they occur.
Wishing you good luck in getting a good diagnosis, your first step toward treatment and hopefully a cure.

But I also think that the "hard bus seat" you mentioned could be the culprit.
An egg-crate pad on the seat might help your leg and foot.
Taking sub-lingual B-12 might help nerve pain.
You want to be able to use the brake, so numbness is not a good sign.
See a doctor please, for your safety, and the safety of any passengers.
Is this a new symptom?
I don't know about your idea of raising one shoe for driving. I think it would be difficult to walk with one shoe raised and would cause back pain. But maybe you could get both shoes raised? Maybe you should check with an ortho doc?
