The Imprint Mast sole makes it very stable (it is not as wide as Clarks Berry but wider than Haley Hawk). Imprint Mast has very good arch support for a ballet flat (about the same as Berry, but better arch support than Haley Hawk, which is still better than most ballet flats). The strap over the arch keeps the shoe on without curling your toes, though the velcro strap can catch fuzz.  I wore it alot after knee surgery because it was easy to slip on without undoing the velcro strap, yet offered fair support. Toe box is roomy. It is a nice casual shoe that is very comfortable for all day walking. The oatmeal color is nice shades of beige and browns. It is a good replacement for Clarks Berry that is no longer available in most sizes. It has more pieces and stitching so it seems stiffer than Berry, but it is still comfortable and I think it will wear longer than Berry.
