A pair of pumps can turn any outfit from drab to fab. We wear them to work and to go out on the town. The word pump is often used to describe a lot of different types of shoes. Pumps have a medium to high heel and cover the back of the foot and the toes, without a strap. Visible parts of the foot include part of the arch, the top of the foot, and a bit of toe cleavage.
Early Heels: Chopines
High heels, some as high as 23 inches were in fashion for upper class women during the Renaissance. These shoes were custom-made and had intricate lacing. In contrast, pumps combined a heel and style with easy slip-on convenience.
Pompes and the Louis Heel
The origin of the word pump in reference to shoes comes from strapless and button-less shoes, "pompes" worn by men and servants in the 1500's. The pump was later elevated to royal status. Pumps with a low and curved heel could be found in the French royal courts of the Louis XIV.
The curved heel is one which comes in and out of style on a pair of pumps, and is called the Louis heel. This particular pump looks strikingly similar to the early pumps of the 1700s. Both styles are round and curvy, with subtle patterning.
In the 1800's more of the top of the foot was shown in silk court shoes. The heel was relatively low, and the Louis heel remained popular in the 1800's.
Modern Pumps
The modern pump, with the narrow heel at the bottom, that we see today first came into fashion in the 1950's.
Pumps were a formal footwear of choice for ladies, including fashion icon Jackie O. The pump, particularly in a plummy pink high heel is still popular, in no small part because of the Sex and the City TV and movie franchise.
