Has anyone here tried Sole footbeds? These are the ones you heat in the oven, then they mold to your foot.

I saw a podiatrist today, I've been having some horrendous foot pain on my longer training walks. Besides having tight calf muscles, I have really high arches. I'm essentially walking on the balls of my feet, regular shoes do not support my arches. There isn't enough time before my half-marathon to get custom orthotics, so he built up a pair of Powerstep innersoles. One feels pretty good, the other feels a little high.

So, I'm thinking of trying the Sole Footbeds. Or carrying an extra set of innersoles when I do the marathon, in case the ones the doctor gave me don't work.

I'm trying my best not to panic.
