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 orflat 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 traditionallybeen made from leather, wood or canvas, but are increasingly made from rubber, plastics, and other petrochemical-derived materials.
Parts
Sole
The bottom of a shoe, the part that is intended to come in repeated contact with the ground, is called the sole. Soles have been made from plant fibers, leather, wood, rubber, synthetics, plastic, and various combinations of these materials. Soles can besimple, a single material in a single layer, or they can be complex with multiple structures or layers and materials.
Insole
See also: Shoe insert and Arch support
The insole is the interior bottom of a shoe, which sits directly beneath the foot under the footbed (also known as sock liner). The purpose of insole is to attach to the lasting margin of the upper, which is wrapped around the lastduring the closing of the shoe during the lasting operation. Insoles are usually made of cellulosic paper board or synthetic non woven insole board. Many shoes have removable and replaceable footbeds. Extra cushioning is often added for comfort (to control the shape, moisture, or smell of the shoe) or health reasons (to help deal with defects in the natural shape of the foot or positioning of thefoot during standing or walking). Basically, this is a main part of shoes which can absorb foot sweat. Footbeds should typically use foam cushioning sheets like latex and EVA, which provide good wearing comfort of the shoe.
Outsole


Parts of a shoe
The outsole is the layer in direct contact with the ground. Dress shoes often have leather or resin rubber outsoles; casual or work-orientedshoes have outsoles made of natural rubber or a synthetic material like Polyurethane. The outsole may comprise a single piece, or may be an assembly of separate pieces of different materials. Often the heel of the sole has a rubber plate for durability and traction, while the front is leather for style. Specialized shoes will often have modifications on this design: athletic or so called cleatedshoes like soccer, rugby, baseball and golf shoes have spikes embedded in the outsole to grip the ground.
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 of the foot, where one puts the most pressure down. Different companies usedifferent materials for the midsoles of their shoes. Some shoes may not have a midsole at all.
Heel
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 and comfortable use.
Vamp (upper)
Every shoehas 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, trainers 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.
