This shoe is very beautiful, sky-high and sexy. The issue for me is that I might have received a defective item.  When I tried to walk in the shoe, there is an imbalance in my gait that almost tipped me over.  This imbalance, I suspect, is caused by the disparate in the construction of the sole of the right foot of the shoe.  A close look revealed that each side of the sole of the shoe is structured differently-one side is higher than the other side. As a result, the heel does not align well with the sole, bringing about a disproportional spatial distance between the heel height and the sole of the shoe/platform; also when I tried to walk on a carpeted floor, the shoe tilted to the right- it is like standing on an uneven surface.
Furthermore, the leather is stiff, and the size 9 that I ordered in patent leather black is snug, yet these are no issues for me.  On charlesdavid.com, it stated that the shoe is made of patent leather, but here, it is listed as man-made upper.  I conjecture it might not be faux leather because Charles David would have listed it as such, since he does for others.  Therefore, I will have to stretch the snugness out a bit.
Over the course of buying from Amazon and myhabit, I have had to return so many shoes, and kept almost a hundred.  Amazon offers these items in extraordinary prices.  When we see these prices, we see great bargains: we think-out of season items, making room for new inventories or overflow due to bad sales projections which forces items to go on sale, and not DEFECTIVE.  Amazon would benefit and save a lot of money in shipment and time, if it could seek out defective items and list them as "New with defect", or "slightly defective", or whatever is wrong with the items so that the buyer will chose  whether to save a penny now, and spend pounds in leg surgery later.
I am tired of making "extraordinary returns", as Amazon is tired of me making them.  Needless to say, I am returning this shoe for an exchange, and hope I get LUCKY to receive one that is not defective.
