I would say that anything being hand-made will never have two of the same, simply because of it being hand-made things can't be perfectly replicated. Also, many ballerinas like to do things to the shoes to make them fit/work better. For example, they'll sew the arches or ankles to provide more support, and will bend the shoe in half so it isn't as stiff.
Nothing is ever exactly the same especially when hand made. And when they are made by a shoe maker they could be made to fit the dancers foot exactly so it if their feet were a little different the pointe shoes would be different.
Yes, sometimes the genitalia of a baby who has intersex traits is noticeably different. ... a new parent trying to figure all this out, know that there's nothing you did or didn't do to “make” your baby intersex.
