(Sorry, only just discovered this thread)

Ockham: If you're still looking for a saddle shoe, my Sensible Shoe project from many months ago might be suitable:

Not technically in the same shape of the old '50s style, but perhaps passable. The shoes have separate material zones for the saddle, main shoe etc - just set the colours you want, use the bumpmap and it comes up nice (somebody posted renders of saddle style on page 2 or 3 of the thread). Being parented props, they are easily fitted to most figures besides V3.
