First of all, let's get one thing straight: TOMS shoes are manufactured in China.
Now, let's review: TOMS thinks you should spend $44+ on a pair of shoes so that, along with your purchase, they can give a pair of shoes to a barefoot child in another country. They think you should spend $44+ on a pair of shoes that cost less than $1 to manufacture (in a police state by slave labor), so that they can give another pair of $1 shoes to a child. I'm no math whiz, but the way I see it they're making $42 in this deal. Or, you know, 42 pairs of shoes.
I have another idea: if you want a shoddy pair of cloth shoes that was made in China, why don't you buy a pair at your local dollar store? That leaves you $43 to invest at Kiva, where you might actually make a difference to a struggling family overseas.
