:My understanding- not being a runner- is that there is a trend towards
:shoes which mimic the mechanics of running barefoot. I've never tried
:'em, since I find running about as enjoyable as endodontistry.

I don't know how much of a trend it is. There are a number of
so-called barefoot shoes available (which, of course, ignores that a
pair of moccosains or sandles did just fine for thousands of years,
but hey! got to sell stuff!), but Nike et al aren't exactly pushing
the market. They're selling a number of shoes that they claim mimic
barefoot movement, but still include massive heel cushions, which
strikes me as selling safer cigarette. They do tend to be more
flexible than traditional running shoes, but that's about it.
