Prefitter has been used successfully for both hair and closed boots. It may not work well for low or open shoes.

Prefitter is a totally different animal than crossdresser of course. Crossdresser is an independent app that gives you a library item where Prefitter is a morph injection that does the bulk of the fitting work to prepare for the fitting room in Poser. The Prefitter works 'on the fly' and allows you to make your own corrections, include your own FBM's and so on.
