just to let you know, i think heels are very uncomfortable. but also, i would have such a hard time walking in them i would probably be wobbling if i wore them! do you want a Kallah who wobbles? and yeah, tznius could be another issue. that’s one more reason i don’t wear them.
i gave you three reasons (two which were mentioned by other posters). i hope it changes your mind about the situation. like others have told you, if that’s the only issue – you’ve found a pretty great girl in my humble opinion.
BE DAN ES KOL HA’ADAM LIKAF ZCHUS – maybe she has a valid reason!
