No1 even tried?
Ofc it has to be done in CM
Who knows the length and width of their shoes??
I can guarantee you this doesn't work, because my feet are slim and my shoe size is 4 sizes smaller than my brother's, but I am taller.
This looks so hard and complicated, I was bad at math. Tell me instead, 42.
I would, but I'm in bed rn so I'll reply tomorrow
the shoes i measured are pretty narrow tbh. 10.5-11 might be a more accurate width
