Nope, just made the dolls big enough to use bought shoes, or else teeny tiny baby shoes. They are getting some real little ones out now, not that any kid that age needs them. But I'll admit that they are sure cute.
Fabric shoes can be made in any shape or size, with stacked cardboard in the heels and soles, then the fabric will be stiffened with paint.
As for foam, I use a "hot" cutter that looks like a cheese slicer, with a long wire that is heated with 2 flash light batteries.
