Calvin Klein Collection, the elite end of the Calvin Klein range, has joined many other labels in producing a high-end classic four inch black work pump. While the territory is well-trodden, each designer has a different tweak on the staple work shoe and the Calvin Klein version is no exception.

The shoe is called Ani, and it’s available in black from Zappos for $545.

The distinguishing feature of this high heel is the subtle change of material used in the upper. Ani is shiny patent leather up until the vamp and bullet-toe, at which point the shoe becomes suede. A further feature is the square cut vamp, which would seem to reveal less toe cleavage than similar pumps by Christian Louboutin and Jimmy Choo.

Ani has a heel height of 4.25 inches. The shoe has leather lining and outsole, and a lightly padded leather insole. See more pictures below, or at Zappos where you can pick up a pair of these new heels for $545.
