A shoe is an item of footwear intended to protect and comfort the
human foot while doing various activities. Shoes are also used as an item of
decoration. The design of shoes has varied enormously through
time and from culture to culture, with appearance originally
being tied to function. Additionally fashion has often dictated many design
elements, such as whether shoes have very high heels or flat ones. Contemporary
footwear varies widely in style, complexity and cost. Basic sandals may consist
of only a thin sole and simple strap. High fashion shoes may be made of very expensive
materials in complex construction and sell for thousands of dollars a pair.
Other shoes are for very specific purposes, such as boots specially designed for mountaineering or skiing.
Shoes
have traditionally been made from leather, wood or canvas, but are
increasingly made from rubber, plastics, and
other petrochemical-derived materials.
The
foot contains more bones than any other single part of the body.
Though it has evolved over hundreds of thousands of years in
relation to vastly varied terrain and climate conditions, the foot is still
vulnerable to environmental hazards such as sharp rocks and hot ground, against
which shoes can protect.
