A boot is a type of footwear. It mainly covers the foot and the ankle and
extends up the leg, sometimes as far as the knee or even the hip. Most
boots have a heel that is clearly distinguishable from the rest of the sole,
even if the two are made of one piece. Traditionally made of leather or
rubber, modern boots are made from a variety of materials. Boots are worn
both for their functionality — protecting the foot and leg from water, snow,
mud or hazards or providing additional ankle support for strenuous activities
— and for reasons of style and fashion.
