You have to change the value of the \spaceskip register when you want to 
change with width of a space.

\startsetups[footnote:space]
   \spaceskip .7\interwordspace plus .5\interwordstretch minus 
\interwordshrink
\stopsetups

\setupnote[footnote][setups=footnote:space]

\starttext

\input zapf
\startfootnote
\input zapf
