"This is too good to be true?"
Um... no... Not at all. Not in the least.
They are your classic fast fashion shoes (http://en.wikipedia.org/wiki/Fast_fashion) fast fashion is cheap. Go into your local Forever 21 and look at the prices, especially the shoe prices. I can buy a whole wardrobe there for under $100.
These shoes aren't built to last. They are built fast and cheaply to capitalize on current trends.
I bought some boots last year for $30, and now they need replacing this year because they are starting to fall apart. I don't wear them every day, or even close to every day, and not during the summer. They were not built to last. I knew they weren't built to last.
