History
The earliest known shoes date from about 8000 to 7000 BCE and were found in Oregon, USA in 1938[1]. However, the materials used for making shoes 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.[1]
Parts of a shoe
Gluing a new outsole to an athletic shoe
Sole
The bottom of a shoe is called the sole.
Insole
The insole is the interior bottom of a shoe, which sits directly beneath the foot. Many shoes have removable and replaceable insoles, and extra insoles are often added for comfort or health reasons (to control the shape, moisture, or smell of the shoe).
Outsole
The outsole is the layer in direct contact with the ground. Dress shoes have leather outsoles; casual or work-oriented shoes have outsoles made of natural rubber or a synthetic imitation. The outsole may comprise a single piece, or may comprise separate pieces of different materials. Often the heel of the sole is rubber for durability and traction, while the front is leather for style. Specialized shoes will often have modifications on this design: athletic cleats have spikes embedded in the outsole to grip the ground; many kinds of dancing shoes have much softer or harder soles.
Midsole
The layer in between the outsole and the insole that is typically there for shock absorption. Some types of shoes, like running shoes, have another material for shock absorption, usually beneath the heel where one puts the most pressure down. Different companies use different materials for the midsoles of their shoes. Some shoes may not have a midsole at all.
Heel
Women's fashion boots
The bottom rear part of a shoe is the heel. Its function is to support the heel of the foot. They are often made of the same material as the sole of the shoe. This part can be high for fashion or to make the person look taller, or flat for a more practical use.
Vamp, or upper
Any shoe has an upper part that helps hold the shoe onto the foot. In the simplest cases, such as sandals or flip flops, this may be nothing more than a few straps for holding the sole in place. Closed footwear, such as boots, sneakers and most men's shoes, will have a more complex upper. This part is often decorated or is made in a certain style to look attractive. The U.S. Patent 3,355,535 , from 1967, describes a method for producing a shoe-upper (Hain 1967).
Accessories to shoes
Shoe horn: can be used to insert a foot into a shoe by keeping the shoe open and providing a smooth surface for the foot to slide upon.
Shoe tree: placed inside the shoe when user is not wearing it, to help maintain the shoe's shape.
Shoe polishing equipment:
Shoe polish: a waxy material spread on shoes to improve appearance, glossiness, and provide protection.
Shoe brush and polishing cloth: used to apply polish to shoes.
Overshoes or galoshes: a rubber covering placed over shoes for rain and snow protection.
(Orthopedic) shoe insert: insert of various materials for cushioning, improved fit, or reduced abrasion. These include padding and inner linings. Inserts may also be used to correct foot problems.
Shoe bag: a bag that protects shoes against damage when they are not being worn.
Shoe stretcher: a tool for making a shoe longer or wider or for reducing discomfort in areas of a shoe.
Snow shoe: a wooden or leather piece which increases the area of ground covered by the shoe.
Shoelaces: a system used to secure shoes.

Dress and casual shoes
Dress shoes are categorized by smooth and supple leather uppers, leather soles, and narrow sleek figure. Casual shoes are characterized by sturdy leather uppers, non-leather outsoles, and wide profile.
Some designs of dress shoes can be worn by either gender. The majority of dress shoes have an upper covering, commonly made of leather, enclosing most of the lower foot, but not covering the ankles. This upper part of the shoe is often made without apertures or openings, but may also be made with openings or even itself consist of a series of straps, e.g. an open toe featured in women's shoes. Shoes with uppers made high to cover the ankles are also available; a shoe with the upper rising above the ankle is usually considered a boot but certain styles may be referred to as high-topped shoes or high-tops. Usually, a high-topped shoe is secured by laces or zippers, although some styles have elastic inserts to ease slipping the shoe on.
Men's shoes
Men's shoes can be categorized by how they are closed:
Balmorals: the vamp has a V-shaped slit to which the laces are attached; also known as "closed lacing". In England, the balmoral is known as the Oxford. The word "Oxford" is used by American clothing companies to market shoes that are not balmorals, such as rubber-sole bluchers.
Blüchers: the laces are tied to two pieces of leather independently attached to the vamp; also known as "open lacing". In England, the Blucher is known as the Derby shoe.
Monk-straps: a buckle and strap instead of lacing
Various other closings exist but are less popular such as side-elastic closings.
Men's shoes can also be decorated in various ways:
Plain-toes: have a sleek appearance and no extra decorations on the vamp.
Cap-toes: has an extra layer of leather that "caps" the toe. This is possibly the most popular decoration.
Brogues (American: wing-tips): The toe of the shoe is covered with a perforated panel, the wing-tip, which extends down either side of the shoe. Brogues can be found in both balmoral and blucher styles.
