Thank you for the tips. Your example boots look fantastic by the way. I had indeed realized that everything was going to hinge on getting the sole right. I haven't tried the box idea yet. I started with a spline shape, extruded then converted to a mesh, but this gives a large number of vertices. What I like about your model is that there do not appear to be many (any) superfluous vertices. This I guess is the big advantage of box modeling. Anyway, once again thanks. I'll post my efforts soon. Regards..... Glenn

Thanks for the tips. I'll definately try anim8or (as it's free). If I get a good solution I'll post it here. Thanks again. Glenn
