I had my doubts about these shoes, but after wearing them at work to break them in, i haven't returned to a regular shoe. My knees don't hurt anymore after work, i rarely have sore legs, and i owe it all to these vibrams. Wearing toe socks took a little getting used to, but after that initial weirdness, i couldn't be happier.
Note.....wear socks with these, because if you dont, they will stink very badly.
ENJOY!

Update: Its been a while since i first got these shoes and i still love them to death. I work as an exterminator so i am walking over different surfaces (rock, gravel, sand, cement, grass) all day every day and i cant describe how comfortable i am in these shoes. Even my "comfy" shoes at home (pumas, clarks, nikes) don't feel as nice as these. Seriously considering making these the only shoes i wear.

I have read reviews complaining of the ease of putting these on, and trust me, its not hard. Also, the foot funk/odor you get while wearing these is an issue, but i have found putting them outside while not wearing them has really curbed that problem. Also, try to wash them at least a couple times a month in the washing machine.....and make sure to velcro them first so they don't stick to eachother in the dryer.
