Interesting thread . . .
I too am a runner. I recently bought a pair of those running shoes with the toes in them. They look like gloves for your feet.
I was warned by the sales clerk to introduce your feet to them gradually, but my feet took to them right away. They fit like a glove (couldn't resist).
My usual run includes passing through a wide creek (the road actually goes right through the creek - neato

); my staus-quo running shoes would take so long to dry, I'd have to remove them, hence my socks, too, before going through the water. Nothing breaks your stride more than having to stop to remove your socks and shoes. Since my new Vibrams have nothing to them - no padding - they dry quickly. I keep 'em on and just keep going: splash, splash, splash.
There's another brand called Skele Toes, too. I don't have the gouge on them, but I do enjoy my Vibrams.
They're great and comfortable. Try them ladies, see what you think: barefeet, but with protection. (I sound like a commercial, sorry.)
