I just ordered these Keen ballet flats: http://www.zappos.com/keen-golden-ballerina-black. and I am super excited to get them in.
I also have these Danskos, but they are too high for me now: http://www.6pm.com/dansko-beth-black-nappa
...and these Keen mary-janes (but, in tan): http://bit.ly/j1Q0VY (I bought them several years ago, so I don't think they sell them anymore though...)
And now you have seen 60% of my shoe wardrobe.
I also have a pair of flip flops that are cushy that I bought at Ross for about $15, and a pair of heels that I haven't worn since I got pregnant... and that's it. Keeps the closet floor relatively clean and makes the "what shoes should I wear" question in the morning a no-brainer. Incidentally, I also only own about 50 pieces of clothing including bags, shoes and coats (it's part of a minimalist movement thingie that keeps me sane these days with all the excess of baby stuff flowing into the house).
