I wanted some basic black slingbacks and bought these as I thought what could go wrong with Manolos? Well in this case quite a lot. My feet can't seem to stay in place when I have these on. The centre of balance seems to be off. The leather on the back of one of the slingbacks is also coming off after a couple of wears. Disappointing as I certainly expected a bit more from Mr. Blahnik! True to size.
