what does mi pies grande son mis zappotas mean

Answer 1

If I'm not mistaken mis pies grande son is my big feet are, and then in spanish you say mis zapatos which means my shoes, see if the last word in correct.

Answer 2

There are several spelling errors in what you wrote. If you really meant
"mis pies grandes son mis zapatos", that means
"my big feet are my shoes"
which does not make much sense.

Answer 3

You could say "Mis pies y mis zapatos son grandes." = My feet and my shoes are big/large.
