Shoe Inserts Taller Height Question....?

Height question....? - shoe inserts taller

OK year, my wife is more than I do. They do not do not bother me at all. But as a woman, it is observed by them. I have repeatedly said that whatever, etc, she stresses that her much. She is 5'11 and I'm 5'8 "tall. I've heard to buy products so that they are bigger. Not sure whether you have an insert in the shoe or shoes in general.

How Does anybody know where I buy a product for daily use? Thanks
