Strangely enough, i never noticed what the womens in Star Trek were wearing for footwear. (The camera also usualy don't point the objectif at their feet!)
I don't know, i supposed it's all depend on your taste and how you want your character to look.
Maybe you can give a look at the " Space Defenders " bundle to give you some idea.

Maybe what the "communication officer" or the " Lunar Research Scientist " (down below in the suggested other product) would be best fit for how you designed your character....just a suggestion.
