I bought these on a whim to wear at a house party of a friend who doesn't wear shoes in her home.  These are awesome! They are super comfortable and store nicely in my small purse.  Since then, I've worn them several times and have even worn them while flying (so now they are outdoor slippers for me).  I plan to buy other colors.  They are thin and my feet were cold when I wore them once in February, but that doesn't take away from how much I like them.
