Some women have feet that take to heels, I have friends that wear them like they are barefoot. Other women want to be stylish and cram their feet in them anyway and ruin their feet. I wore heels rarely when I was younger, and still messed up my feet. I never wear heels now, pretty sure I wouldn’t be able to walk in them.
As gracefully as Melania walks I would bet heels fit her feet pretty well. Who knows though, she just may be toughing it out.
You just get used to wearing heels. I worked 2 jobs in 3 inch heels for 20 years. 8 to 5 and then 6 to 2. Flats felt funny. Took me awhile to get used to flats but now that I am heels are hard again.
