These Birks are stylish and comfortable.  I bought both the silver and bronze because I like them so much.  They are easy to slip on and off, but they don't fly off your feet if you kick or dangle your feet like some open back shoes do.  They take a little breaking in to be as comfortable as possible, but they are pretty comfortable immediately.  The silver color, especially, is very cute and stylish looking.  These aren't your hippy grandmother's sandals!
