I have two pairs of shoes with this type of a heel. One of them is COS and the other Dries Van Noten, from his S/S 2011 collection. I call this heel shape “Dries” since I think he was the first to design it (please correct me if I’m wrong).
It’s great, right? A pump/wedge hybrid, that goes great with just about anything. And so comfortable to walk in.
