I believe you can as long as both shoes (for instance) share the same texture map.

I hope that makes sense.

I suggest, if you don't already have it, you download a copy of UV Mapper Pro. Its inexpensive and does the job you are looking to do.

You will have to export or save both (shoes) as a single OBJ file and then open it in UV Mapper. See Dan over in the UV Mapper forum for more details.

Good luck.
