Just scored these babies during Macy's recent sale, I think that the heel is unusual and very stable, btw! the sole has a groove so the weight of the body is distributed on each side rather than in the middle. I think these shoes are very well designed. The insole is some sort of woven raffia type of material which absorbs moisture. And of course, yummy chocolate patent leather!!! What do you, guys, think? This is my first shoe post with pics!
