Completely agree with you. I've been using a standup for about a year now, details here: http://www.localconspiracy.com/2010/08/get-up-stand-up.html http://www

Completely agree with you. I've been using a standup for about a year now, details here: http://www.localconspiracy.com/2010/08/get-up-stand-up.html http://www.localconspiracy.com/2010/08/get-up-stand-up.html Regarding the feet, barefoot (on a gel mat) is about as good as it gets. But I've been running barefoot for two years now, so my opinion is biased. Since switching to standup, I've almost ZERO back problems. Prior to this, I used to have serious back pain for two or three days at a time, several times a year.
