I bought the Windham slip on flat from the Grasshopper website, but they do have allow comments.

I've worn these around the house for a few hours before deciding to keep them  They are soft, comfortable and don't have any seams that rub in the wrong places.  The only caveat I have is level of support from the "Ortholite insole".  The insert is comfortable, but offers little or no arch support.  I have orthotics for most of my shoes and after reading comments, thought that these shoes would not need them.  They do.  Fortunately, the footbed comes out easily to accommodate the insert, and the shoe is not too tight after the orthotic is added.
