I noticed that Tom Ford has many variations of this booties. There are open toe, thigh high, and ankles versions I saw the Tom Ford Zipper-Heel Leather Ankle Boots in a magazine and thought I know some has done a look for less on these. I think the zipper detail in the back is dope. ZIGIny has a similar design with their Tabatha Zipper Booties.
