Size 40M. Jimmy Choo sizing chart equates this to a 10. I'm typically a 10 and I would say they fit true to size. Adjustable ankle strap, incredibly soft brown calfskin leather, stud detail at sole with peep toe, 3.5 inch block heel. Excellent used condition (wore 1-2 times, see photo of soles). Purchased at Gwynn's of Mount Pleasant and just don't end up wearing them much! Includes original box and dust bag.
