Hello again, students of the shoe encyclopedia class. Already those of you who have been keeping up have learned so much. For those of you new to the shoe encyclopedia (or a touch behind), don't forget to go back and study the previous lessons to get up to speed. In case your memory on the encyclopedia of shoes needs some jogging, the last lesson included information on RadianTex, waterproofing silicone, thermoplastic rubber and thermoplastic urethane. This time around, the shoe encyclopedia will teach you about two types of heels (the Louis heel and the kitten heel). It also will school you on the plug, as well as the brogan.

Louis Heel
The Louis heel is a high-heeled shoe that features fancy curves on the back and sides of the heel. The curve looks similar to an hourglass shape. The original Louis heel was worn by Louis XV, the inspiration for the name and style. However, today Louis heels are more commonly worn by women.

Kitten Heel
A heel that is low to the ground and tapers off into a narrow base is known as a kitten heel. These are featured in women's heels. A kitten heel can be found in both casual shoes and dressy styles. Shoes that feature a kitten heel could be sandals, strappy shoes, slide-ons, open-toed or closed. A variety of styles can feature a kitten heel.

Plug
Plug? Are we talking plumbing, like sinks and tubs? Nope, we're still on shoes. In shoe terms, a plug is not related to stopping a drain, thank goodness. Although, that certainly would make for an interesting pair of shoes. I just can't figure out what the plug would hold in - hopefully not water. No, in shoe terms, a plug refers to the center of the upper area in a moccasin.

Brogan
Also known as the brogue or the clodhopper, a brogan is a heavy shoe that is very thick. Brogan shoes can come in a wide variety of styles, ranging from tennis shoes to heels and even boots. Many heavier shoes are considered to be brogan shoes.
