If you look closely at BOBS, they have the same layout on the shoes even! On the outer side when you are wearing BOBS, you see the little tag with the brand name like the TOMS shoes. I think that the point of TOMS was to inspire other businesses to get one and then give one, but not to steel the entire look of them. This isn't the only scam though, The Spring 2012 Twinkle Toes are one of the others. The Spring 2012 Twinkle Toes have the same TOMS look to them, except with sparkles and LOTS of colors. Not all Twinkle Toes are like this though, just some of the new Spring styles. If I were you, I'd stick with TOMS.
