I love these shoes!  They are very comfortable, lightweight and cute.  I've worn them for walks and also with jeans and a sweater.  The patent look (mine are black) makes them look like regular ballet flats and not like an athletic shoe.  No blisters!  I would say they don't have a lot of arch support, which didn't bother me, but might bother some.  There is definitely room for an insert though if that normally bothers you.  They are also slightly wide and might not be great for someone with extremely narrow feet.

Bottom line, these are great flats and would be perfect for traveling (I bought mine for an upcoming Europe trip), a day at Disney World, and every day errands.  I'm going to buy them in more colors!
