Just bought my second pair of green canvas Toms.  Wore the first pair into the ground over the course of a year and a half.  My girlfriend bought them for me, and though I was skeptical at first, they quickly became my favorite shoes.  The best part about them is that they really breathe, and I can wear them day after day without socks and they pick up no odor to speak of.  I've also grown to really like the way they look, and I get complimented a lot on them.

Listen, they aren't made for running in, and they don't offer much support, but they are fantastic summer shoes.  I don't mind paying a few bucks extra when it's going to a good cause.  I've noticed various knockoffs surfacing at places like Kohl's, and to me that really misses the point.  Buy 'em.
