These. Are. Adorable. I bought these a couple months ago and now they are only $14.99! The heel is great and these seem comfy so far. They come in four different colors!
I went up to a 9 and I am normally an 8.5 or 9. Get 'em while they're hot and before every other gal at the office has them. Bonus: wedges add calf muscles, or at least the illusion you've been doing waaay more squats than you really have.
