In the past, I have purchased ACORN Women's Chinchilla Mule Slippers and I loved the style. The footbed offers great cushioning for my feet against my tile floors.  I decided to try a different style this time, the Digby.  I find that it runs a full size smaller than my previous style.  Although it has the great Acorn footbed cushion,  the trim binding around top of the slipper opening has little "give" and is uncomfortable with my high instep.  This styling would likely pose a problem for someone with a wide foot too.
