Just received these yesterday and have worn them all day today at work.  Very comfy shoes.  Especially for those of us who have high instep and tend to walk out of our heals with regular loafer style shoes. the elastic strap keeps them secure and in place and I haven't walked out of them at all.  I am definately considering ordeing more in the different colors.  Size for me ran true and there was no problem with them being short or tight in the toe area.  Also they are very light and feel like a slipper on your foot.  I would recommend them for any high instep/high arch person.
