It was a rather boring post and I'm afraid you do seem to come across as someone who's prepared to spend money on any new gimmick. Negative heel shoes in particular sound like a very bad idea.
Mind you, if Vibram really make toe socks that slip down, I'm deeply unimpressed.
I love driving in my VFFs, CJ! If it's a long drive, then a quick stretch of the legs round a service station carpark does wonders for waking your body back up again.
