Anybody have any experience with either of these brands? I read an article on Corporette that described these as the most comfortable of the heels, and I'm wondering how they'd hold up. NB: Self-described heel-hater, but there are certain occasions where they are necessary. Flat feet and nasty hereditary bunions mean that heels aren't part of my daily wear, but I would like to own one nice pair of heels for upcoming significant occasions.
