I hear you, but I actually agree with your Rov.
Although I don’t know if your post is serious, I do have much experience in this area, I honestly am shocked at your friends advice. Get wiser friends. Either they are very young, fresh out of the freezer, or similar, then I understand the inexperience.
If they are older than 23, then dude! Don’t take their advice in dating. It’s your future, not theirs, get some wiser counsel.
I don’t think you should let a pair of high heels, come between you and your potential life partner. Flats are cool too, and super comfortable. So be cool!
Wishing you much Hatzlacha in finding your Bashert.
