Yes you can, but only if you use the brown Collonil Wax Polish Collonil Wax Polish (1x) for the black shoes!😄

Collonil 1909 Supreme Creme de Luxe (100ml, 1x)

You can also repair a red car with black paint, but then it will be black instead of red. It's the same with shoe polish. It is black and makes shoes black after application.
