wedding shoes

Initials or Rhinestone letters on bottom of wedding shoes?

I never people did this until i started looking at pics and planning on the internet!
Is this an old tradition?
Any info will be appreciated!
Supposed to say ….Never knew people did this*
I am surprised! the reason i asked this here is because I thought maybe I was the only girl who never head of this tradition!! But honestly, in everyyy pic Ive seen, then Brides have it!

I have seen that too, but traditionally, you should not wear or use your fiance’s monogram before you are married. so if you get your shoes with them on it, when you walk down the aisle you’ll be using his monogram too soon, and that is bad luck
