Hello,
What kind of superscripts are you referring to? If they are the symbols for
footnotes, then maybe you should look at how the footnote is defined, maybe
something like \footnotetext or something. In that case, it also depends on
which class file you are using, I think that memoir offers more options than
other classes to customize things like footnotes.
If you are using superscripts in a kind of mathematical way, i.e. not in a
footnote, then you might try $^\mathrm{foo}$, although I am not sure about the
spacing in that case.
