I bought these for my best friend's wedding (she has a pair, too!) so that I could have the color she wanted as well as comfort.  I was in these all day and they are very comfy.  I did wear them out one night prior to the wedding for a few hours to break them in.  And that's all that's needed.  The little arch pillow is a nice addition, making these (in my opinion) more comfortable than regular flats (or TOMS).  I would describe them as "true to size"...after a little stretch.  They WILL stretch, so get them in your size.

The best bonus is that a pair of shoes goes to kids in need.  Make your feet and heart feel good!

The sparkle in these is also far more intense than the photo shows...but that's hard to display in a picture sometimes.
