One of my wardrobe holes is a pair of simple black heels. I have decided to try wedges, and came across these at Zappos. Has anyone tried them? My particular foot problems include a skinny heel (foot slips out all the time), the start of a bunion, and plantar fasciitis. These shoes look promising, but I hesitate to order them blind. The price is good though, for the few times I need a black heeled shoe.
