Most of the time there have been people, most people have not worn shoes. Until recent years, shoes were not worn by most of the world's population—largely because they could not afford them. Only with the advent of mass production, making available for the first time the cheap flip-flop-type sandal, for example, has shoe-wearing become predominant.

Appearance and design have varied enormously through time, and from culture to culture. They may, for example, have very high heels or no heels at all. Contemporary footwear varies in style, complexity and cost, from the most basic sandal, via high fashion shoes for women sometimes costing thousands of dollars a pair, through to complex 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.

History

The earliest known shoes date from about 8000 to 7000 BCE and were found in Oregon, USA in 1938. However, the materials used for making shoes (typically tanned leather) do not normally last for thousands of years, so shoes were probably in use long before this. Physical anthropologist Erik Trinkaus believes he has found evidence that the use of shoes began in the period between about 40,000 and 26,000 years ago, based on the fact that the thickness of the bones of the toes (other than the big toe) decreased during this period, on the premise that going barefoot results in greater bone growth before this period.

The earliest designs were simple affairs, often mere "foot bags" of leather to protect the feet from rocks, debris, and cold. Since a shoe uses more leather than a sandal, their use was more common amongst people in cold climates. By the Middle Ages, turn-shoes had been developed with toggled flaps or drawstrings to tighten the leather around the foot for a better fit. As Europe gained in wealth and power, fancy shoes became status symbols. Toes became long and pointed, often to ridiculous proportions. Artisans created unique footwear for rich patrons, and new styles developed. Eventually the modern shoe, with a sewn-on sole, was devised. Since the 17th century, most leather shoes have used a sewn-on sole. This remains the standard for finer-quality dress shoes today.

Since the mid-20th Century, advances in rubber, plastics, synthetic cloth, and industrial adhesives have allowed manufacturers to create shoes that stray considerably from traditional crafting techniques. Leather, which had been the primary material in earlier styles, has remained standard in expensive dress shoes, but athletic shoes often have little or no real leather. Soles, which were once laboriously stitched on, are more often glued today.
