Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.

Worth the Money for a good shoe
Size: 9, Color: Chestnut
These shoes are well worth the money. I am on my feet a large portion of day. I have to have a shoe that is comfortable, but looks good. My feet swell as the day progresses and these allow for adjustments to be made so they are not tight. My feet do not hurt after wearing these and my swelling seemed to be less than usual. I received many compliments and the color matches a wide range of outfits. The straps allow for stability to my ankles. I will be purchasing these shoes on black also.
