I measured my feet, checked my size on a chart and bought a pair of high heels. Apparently women’s feet are thinner than men’s, but I never thought they were that much thinner. Shoe fits but it hurts.
Foot measures are 27 cm long and 10 cm wide across the ball (10.62’’ long and 3.93’’ in imperial)
I compared the heels to my unisex sneakers: sneakers are 11 cm (4.33’‘) wide across the ball and the heels 7.5 cm (2.95’').
I don’t believe any heel brand makes 10 cm (3.93’') wide heels.
People have recommended me to go a bigger size, but a larger size is going to be longer and will fall off.
If youre comfortable enough to risk getting outed IRL, theres are certain vendors that cater specifically to crossdressers. The ones I saw were crazy expensive and weren’t particularly pretty. They’d tried to make them pretty but I think theres only so much they can do when focusing on size and strength
