I'm about to begin a pep/foam hybrid iron man build and im just curious if anyone has any good ideas about how to add some height while in the suit. I'm 5'11" and would like to have more of a superhero presence while wearing the suit. I was thinking at least 6'2". I was thinking I could just build up the bottom of the shoe but I'm not sure how this would effect the knee joint or overall proportions. Any and all ideas would be appreciated.
