I am only 4 months 3 weeks on HRT, so still a little early for any significant changes like that to occur, but I have read multiple cases where Transwomen have gotten shorter and lost shoe sizes. I don't really understand how this is possible, and I sure wish it would happen to me, because I am 6'1" and wear a size 12 mens shoe. It is very dysphoria agravating to me to look down at my huge manly feet, and feeling like I am towering over all of the girls around me. It sucks! So I am greatly looking forward to any potential "shrinkage". But definitely not expecting it.
