I remember seeing a program a number of years ago on a treatment for the feet in japan or china I think. basically you walk along a path made up of lots of pebbles laid on their end. The presenter of the show couldnt walk on the stones without the aid of a rail to support himself but people who performed the therapy could without problem.
I believe it was meant to act as a massage for the feet and improve suppleness. does anyone know anything about this? Does it sound like a useful therapy (my feet are quite stiff, especially the arches)?
