Anybody use "Arch Molds"?

In case you haven’t heard of them they are heat moldable footbeds that you pop in the oven for a short time at a pretty low temp and then wear them as they mold to your feet.

Has anyone had experience with them. I wear orthotics and would like to use these for some races and training.

I bought a pair Saturday and ran 4 easy miles Sunday in a new pair of shoes (Fila Redemption) and they seemed to do pretty well.

Has anyone else tried them?
