Yes, I have a pair of 75mm size 7 stilettos I can easily walk around in. I practiced first with kitten heels of the same size and brand. Some nights they are a little tight, so I've learned to hold my toes together to improve the fit! I always wear them with bare feet. I think it helps that they are leather and not some sort of plastic.
I did have trouble with them coming off one of my feet, which isn't as well coordinated as the other one. But now I don't have any problems, even when the heel catches on the edge of a area rug.
