Learn about Shoes
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 form originally being tied to function. Though the human foot can adapt to varied terrains 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-toe boots which are required footwear at industrial worksites.
Additionally, fashion has often dictated many design elements, such as whether shoes have very high heels or flat ones. Contemporary footwear 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 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.[1] Globally, the shoe industry is a $200 billion a year industry.[1] 90% of shoes end up in landfills, because the materials are hard to separate, recycle or otherwise reuse.[1]
What about Sneakers
Sneakers (also called trainers, athletic shoes, tennis shoes, gym shoes, kicks, sport shoes, flats, running shoes, or runners) are shoes primarily designed for sports or other forms of physical exercise, but which are now also widely used for everyday casual wear. Since their popularization by companies such as Converse, Nike and Spalding in the mid 20th century, they have become attire, with variety growing in many global markets exponentially. Like other parts of the global clothing industry, manufacture of shoes is heavily concentrated in Asia with nine in ten shoes produced in that region.[1]
Contemporary sneakers are largely made from synthetic materials, and the materials and manufacturing process produce, on average, about 14 kg (31 lb) of CO2 emissions.[2][3] Some companies are trying to substitute more sustainable materials in their manufacture.[3] About 90% of shoes end up in landfills at end of life.[4]
