These flats are genuine leather with a split foldable rubber sole. Perfect for popping in your handbag if you think you may need to step out of those heels ;) With a padded inner sole and soft leather construction, you should be able to wear these straight away with no breaking in!
Sizing: I have found sizing to be somewhat flexible with these amazing flats. Most will find them to be very true to their normal shoes size. If you wear a whole to half size (ie 7-7.5) with a more narrow foot, you should be able to size down to the whole size just fine. If you wear a half size and have a wider foot, Then size up to the next whole size. This seems to be the general size rule from customer reviews.
* These are a special edition print. Once they are gone, they are gone! So get your hands on them!
