I wore my old ones basically EVERYDAY this past year to work, hanging out and casual evenings. I love these because they are fashionable, comfortable and don't feel like you're completely walking barefoot. They don't have that annoying elastic in the back that kill your heels and don't cram your toes.
These flats support your feet with a rubber platform like a gym shoe. Best of all, the rubber platform is nearly invisible! It's not noticeable when you walk. From a far it looks like any other flat shoe. This shoe now comes in just about every color this year from navy to pomegranate.
The least you can do for your body is take care of what carries its weight, your feet!
