A shoe is an item of footwear intended to protect and comfort the human foot. Shoes are also used as an item of decoration and fashion. 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 in the s varies widely 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 hundreds or even thousands of dollars a pair. Some shoes are designed for specific purposes, such as boots designed specifically for mountaineering or skiing.
Traditionally, shoes have been made from leather, wood or canvas , but in the s, they are increasingly made from rubber , plastics , and other petrochemical -derived materials. Though the human foot is adapted to varied terrain and climate conditions, it is still vulnerable to environmental hazards such as sharp rocks and temperature extremes, which shoes protect against. Some shoes are worn as safety equipment, such as steel-soled boots which are required on construction sites.
The earliest known shoes are sagebrush bark sandals dating from approximately or BC, found in the Fort Rock Cave in the US state of Oregon in It is thought that shoes may have been used long before this, but because the materials used were highly perishable, it is difficult to find evidence of the earliest footwear.
This led archaeologists to deduce that wearing shoes resulted in less bone growth, resulting in shorter, thinner toes. They were more commonly found in colder climates. Many early natives in North America wore a similar type of footwear, known as the moccasin.
These are tight-fitting, soft-soled shoes typically made out of leather or bison hides. Many moccasins were also decorated with various beads and other adornments. Moccasins were not designed to be waterproof, and in wet weather and warm summer months, most Native Americans went barefoot. As civilizations began to develop, thong sandals the precursors of the modern flip-flop were worn. This practice dates back to pictures of them in ancient Egyptian murals from BC. One pair found in Europe was made of papyrus leaves and dated to be approximately 1, years old.
They were also worn in Jerusalem during the first century of the Common Era. Ancient Egyptian sandals were made from papyrus and palm leaves. The Masai of Africa made them out of rawhide. In India they were made from wood. In China and Japan, rice straw was used. The leaves of the sisal plant were used to make twine for sandals in South America while the natives of Mexico used the Yucca plant. While thong sandals were commonly worn, many people in ancient times, such as the Egyptians , Hindus and Greeks , saw little need for footwear, and most of the time, preferred being barefoot.
The Egyptians and Hindus made some use of ornamental footwear, such as a soleless sandal known as a "Cleopatra", [ citation needed ] which did not provide any practical protection for the foot. The ancient Greeks largely viewed footwear as self-indulgent, unaesthetic and unnecessary. Shoes were primarily worn in the theater, as a means of increasing stature, and many preferred to go barefoot.
The runners of Ancient Greece are also believed to have run barefoot. The Romans , who eventually conquered the Greeks and adopted many aspects of their culture, did not adopt the Greek perception of footwear and clothing. Roman clothing was seen as a sign of power, and footwear was seen as a necessity of living in a civilized world, although the slaves and paupers usually went barefoot. A common casual shoe in the Pyrenees during the Middle Ages was the espadrille.
This is a sandal with braided jute soles and a fabric upper portion, and often includes fabric laces that tie around the ankle. The term is French and comes from the esparto grass.
The shoe originated in the Catalonian region of Spain as early as the 13th century, and was commonly worn by peasants in the farming communities in the area. Many medieval shoes were made using the turnshoe method of construction, in which the upper was turned flesh side out, and was lasted onto the sole and joined to the edge by a seam.
The shoe was then turned inside-out so that the grain was outside. Some shoes were developed with toggled flaps or drawstrings to tighten the leather around the foot for a better fit. Surviving medieval turnshoes often fit the foot closely, with the right and left shoe being mirror images. By the 15th century, pattens became popular by both men and women in Europe. These are commonly seen as the predecessor of the modern high-heeled shoe ,  while the poor and lower classes in Europe, as well as slaves in the New World, were barefoot.
The style is characterized by the point of the shoe, known as the "polaine", which often was supported by a whalebone tied to the knee to prevent the point getting in the way while walking.
These shoes became popular in Venice and throughout Europe, as a status symbol revealing wealth and social standing. During the 16th century, royalty, such as Catherine de Medici or Mary I of England , started wearing high-heeled shoes to make them look taller or larger than life. By , even men wore them, and a person with authority or wealth was often referred to as, "well-heeled".
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. Until around , welted rand shoes were commonly made without differentiation for the left or right foot.
Such shoes are now referred to as "straights". Shoemaking became more commercialized in the midth century, as it expanded as a cottage industry. Large warehouses began to stock footwear, made by many small manufacturers from the area. Until the 19th century, shoemaking was a traditional handicraft, but by the century's end, the process had been almost completely mechanized, with production occurring in large factories.
Despite the obvious economic gains of mass-production , the factory system produced shoes without the individual differentiation that the traditional shoemaker was able to provide. The first steps towards mechanisation were taken during the Napoleonic Wars by the engineer, Marc Brunel. He developed machinery for the mass-production of boots for the soldiers of the British Army. In , he devised a scheme for making nailed-boot-making machinery that automatically fastened soles to uppers by means of metallic pins or nails.
In the same year, the use of screws and staples was patented by Richard Woodman. Brunel's system was described by Sir Richard Phillips as a visitor to his factory in Battersea as follows:. In another building I was shown his manufactory of shoes, which, like the other, is full of ingenuity, and, in regard to subdivision of labour, brings this fabric on a level with the oft-admired manufactory of pins. Every step in it is effected by the most elegant and precise machinery; while, as each operation is performed by one hand, so each shoe passes through twenty-five hands, who complete from the hide, as supplied by the currier, a hundred pairs of strong and well-finished shoes per day.
All the details are performed by the ingenious application of the mechanic powers; and all the parts are characterised by precision, uniformity, and accuracy. As each man performs but one step in the process, which implies no knowledge of what is done by those who go before or follow him, so the persons employed are not shoemakers, but wounded soldiers, who are able to learn their respective duties in a few hours. The contract at which these shoes are delivered to Government is 6s.
However, when the war ended in , manual labour became much cheaper, and the demand for military equipment subsided. As a consequence, Brunel's system was no longer profitable and it soon ceased business. Similar exigencies at the time of the Crimean War stimulated a renewed interest in methods of mechanization and mass-production, which proved longer lasting. His machine used an iron plate to push iron rivets into the sole.
The process greatly increased the speed and efficiency of production. He also introduced the use of steam-powered rolling-machines for hardening leather and cutting-machines, in the mids. The sewing machine was introduced in , and provided an alternative method for the mechanization of shoemaking.
By the late s, the industry was beginning to shift towards the modern factory, mainly in the US and areas of England. A shoe stitching machine was invented by the American Lyman Blake in and perfected by Entering into partnership with McKay, his device became known as the McKay stitching machine and was quickly adopted by manufacturers throughout New England.
By the s, the process of mechanisation was largely complete. On January 24, , Humphrey O'Sullivan of Lowell, Massachusetts , was awarded a patent for a rubber heel for boots and shoes.
Since the midth 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 hand-stitched on, are now more often machine stitched or simply glued on. Many of these newer materials, such as rubber and plastics, have made shoes less biodegradable.
It is estimated that most mass-produced shoes require years to degrade in a landfill. However, many manufacturers in Europe dominate the higher-priced, higher value-added end of the market.
As an integral part of human culture and civilization, shoes have found their way into our culture, folklore, and art. This story tells about an old woman living in a shoe with a lot of children. In , Mahlon Haines , a shoe salesman in Hallam, Pennsylvania , built an actual house shaped like a work boot as a form of advertisement.
The Haines Shoe House was rented to newlyweds and the elderly until his death in Since then, it has served as an ice cream parlor, a bed and breakfast , and a museum.
It still stands today and is a popular roadside attraction. Shoes also play an important role in the fairy tales Cinderella and The Red Shoes. In the movie adaption of the children's book The Wonderful Wizard of Oz , a pair of red ruby slippers play a key role in the plot. The comedy The Man with One Red Shoe features an eccentric man wearing one normal business shoe and one red shoe that becomes central to the plot.
Athletic sneaker collection has also existed as a part of urban subculture in the United States for several decades. A contributor to the growth of sneaker collecting is the continued worldwide popularity of the Air Jordan line of sneakers designed by Nike for Basketball star Michael Jordan.
In the Bible 's Old Testament , the shoe is used to symbolize something that is worthless or of little value. In the New Testament , the act of removing one's shoes symbolizes servitude.

Foot plantar pressure is the pressure field that acts between the foot and the support surface during everyday locomotor activities. Information derived from such pressure measures is important in gait and posture research for diagnosing lower limb problems, footwear design, sport biomechanics, injury prevention and other applications. This paper reviews foot plantar sensors characteristics as reported in the literature in addition to foot plantar pressure measurement systems applied to a variety of research problems. Strengths and limitations of current systems are discussed and a wireless foot plantar pressure system is proposed suitable for measuring high pressure distributions under the foot with high accuracy and reliability. The novel system is based on highly linear pressure sensors with no hysteresis. The development of miniature, lightweight, and energy efficient circuit solutions for healthcare sensor applications is an increasingly important research focus given the rapid technological advances in healthcare monitoring equipment, microfabrication processes and wireless communication. One area that has attracted considerable attention by researchers in biomedical and sport related applications is the analysis of foot plantar pressure distributions to reveal the interface pressure between the foot plantar surface and the shoe sole.
