gcardell, OP asks a question and if you can't answer it then STFU. Posting humorless pics can be annoying the third or fourth time around.
To the OP, have you thought of going bespoke? I can't imagine it being too difficult to sneak in a few cm's at Lobb's or Beluti's if you can engineer the shoes from scratch. Personally, I think you have a solid height. Any taller, you won't be able to help old ladies crossing the street.
i went to a physical therapist about my lordosis and they said strengthening the stomach and stretching the hip flexors was the way to minimize it. I did just that and didn't notice anything. I think the popular conception of how straight the lower back should curve is unrealistic- nearly all the aboriginal tribespeople you see on tv have a very pronounced lordosis... I think it's the sign of a strong lower back/gluteul muscles.
Lordosis (Wikipedia) I hope your doctor has given you permission to wear the funny shoes because wearing those things with your medical condition without oversight sounds pretty fucking stupid to me. How about asking a specialist about appropriate shoes and requirements for your condition?
