Aparently, I am some sort of lucky, because I am 180 cm (5'11) and wear EU 41, which should be women's 9,5 - 10 US, depending of the converter. I know several even shorter cis girls, that wear the same size as me, so I have not big problems finding shoes.
In fact, before I started HRT, I wore one size bigger shoes - EU 42, which should be 10,5 or 11 US and my foot size was around 27 cm - now it is 26, so obviously there is a change

I don't know if it happens to everyone, but if I have to be honest, I didn't believe it, until it happened.
