Shoe

A shoe is an item of footwear normally found in pairs intended to protect and comfort the human foot, usually made in such a way that one is designed to fit the left foot and the other the right foot.

Shoes are intended to provide further protection to the vulnerable human foot, though the foot is highly adaptable to various terrains. Form was originally tied to function, but over time, shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.

Additionally, shoes have often evolved into many different designs; high heels, for instance, are most commonly worn by women during fancy occasions. Contemporary footwear varies vastly in style, complexity and cost. Basic sandals may consist of only a thin sole and simple strap and be sold for a low cost. High fashion shoes made by famous designers may be made of expensive materials, use complex construction and sell for large sums of money. Some shoes are designed for specific purposes, such as boots designed specifically for mountaineering or skiing, while others have more generalized usage such as sneakers which have transformed from a special purpose sport shoe into a general use shoe.

Traditionally, shoes have been made from leather, wood or canvas, but are increasingly being made from rubber, plastics, and other petrochemical-derived materials.
