Very comfortable in 1/2 size bigger than my normal 6 1/2.
I bought these in the Clark's store because I need to try on flats in person since I've had problems with rubbing in these styles too many times.
All the other Clark's flats in the store were comfortable for me in a 6 1/2, but with these it was the 7 that worked.
I like that the little edge of soft, stretchy fabric around the opening isn't a ribbon stitched directly over the leather's edge like so many other brands (might as well be sandpaper in most cases).  I also like the foot-bed and lining, which feel well-made and cushy with out adding too much bulk to the look of the shoe.
Kind of expensive, but I've had way too many pairs of cheapo flats that tore up my feet until they were broken in, at which point they were almost ready to be replaced!
