Personalised Running Shoes Anyone?

Whilst surfing through some running blogs the other night I came across these new concept shoes, which apparently are moulded to your specific foot, and need to be worn in incrementally, to get your feet used to walking then running in them. I reckon I'd be interested in using htem for beach running, but the cost would probably be prohibitice. The Nike shoe which is designed to replicate barefoot running would no doubt be cheaper.

The are called Vibram Five Fingers, and you can check the website out here

I think I will try melting my old wellington boots around my foot later on and see if I can get something like this going!
