I have the Adidas adipure trainer toe shoes, and after not wearing them for a few months, I put them on and noticed how uncomfortable and gross they have gotten, so instead of buying more, I bought these Vibrams...

BEST SHOES I'VE EVER OWNED!!!!

They do take some getting used to, but once you've adjusted, you'll be building muscles in your legs and feet you never knew existed!  Some advice, use Vibram's sizing chart, measure accurately, and buy a size that will fit pretty tight because they feel better tighter than looser and they will loosen up a bit.
