There are a wide variety of different types of<unk> s. Most types of<unk> s are designed for specific activities. For example, boots are typically designed for work or heavy outdoor use. Athletic<unk> s are designed for particular sports such as running, walking, or other sports. Some<unk> s are designed to be worn at more formal occasions, and others are designed for casual wear. There are also a wide variety of<unk> s designed for different types of dancing. Orthopedic<unk> s are special types of footwear designed for individuals with particular foot problems or special needs. Clinicians evaluate patient’s footwear as a part of their clinical examination. However, it is often based on each individual’s needs, with attention to the choice of footwear worn and if the<unk>  is adequate for the purpose of completing their activities of daily living. Other animals, such as dogs and horses, may also wear special<unk> s to protect their feet as well. Depending on the activity for which they are designed, some types of footwear may fit into multiple categories. For example, Cowboy boots are considered boots, but may also be worn in more formal occasions and used as dress<unk> s. Hiking boots incorporate many of the protective features of boots, but also provide the extra flexibility and comfort of many athletic<unk> s. Flip-flops are considered casual footwear, but have also been worn in formal occasions, such as visits to the White House. Athletic A pair of athletic running<unk> s Athletic<unk> s are specifically designed to be worn for participating in various sports. Since friction between the foot and the ground is an important force in most sports, modern athletic<unk> s are designed to maximize this force, and materials, such as rubber, are used. Although, for some activities such as dancing or bowling, sliding is desirable, so<unk> s designed for these activities often have lower coefficients of friction. The earliest athletic<unk> s date back to the mid 19th century were track spikes—leather<unk> s with metal cleats on the soles to provide increased friction during running. They were developed by J.W. Foster & Sons, which later become known as Reebok. By the end of the 19th century, Spalding also manufactured these<unk> s as well. Adidas started selling<unk> s with track spikes in them for running and soccer in 1925. Spikes were eventually added to<unk> s for baseball and American football in the 20th century. Golfers also use<unk> s with small metal spikes on their soles to prevent slipping during their swing. The earliest rubber-soled athletic<unk> s date back to 1876 in the United Kingdom, when the New Liverpool Rubber Company made plimsolls, or sandshoes, designed for the sport of croquet. Similar rubber-soled<unk> s were made in 1892 in the United States by Humphrey O'Sullivan, based on Charles Goodyear's technology. The United States Rubber Company was founded the same year and produced rubber-soled and heeled<unk> s under a variety of brand names, which were later consolidated in 1916 under the name, Keds. These<unk> s became known as, "sneakers", because the rubber sole allowed the wearer to sneak up on another person. In 1964, the founding of Nike by Phil Knight and Bill Bowerman of the University of Oregon introduced many new improvements common in modern running<unk> s, such as rubber waffle soles, breathable nylon uppers, and cushioning in the mid-sole and heel. During the 1970s, the expertise of podiatrists also became important in athletic<unk>  design, to implement new design features based on how feet reacted to specific actions, such as running, jumping, or side-to-side movement. Athletic<unk> s for women were also designed for their specific physiological differences. A pair of Converse All-Stars<unk> s specific to the sport of basketball were developed by Chuck Taylor, and are popularly known as Chuck Taylor All-Stars. These<unk> s, first sold in 1917, are double-layer canvas<unk> s with rubber soles and toe caps, and a high heel (known as a "high top") for added support. In 1969, Taylor was inducted into the Naismith Memorial Basketball Hall of Fame in recognition of this development, and in the 1970s, other<unk>  manufacturers, such as Nike, Adidas, Reebok, and others began imitating this style of athletic<unk> . In April 1985, Nike introduced its own brand of basketball<unk>  which would become popular in its own right, the Air Jordan, named after the then-rookie Chicago Bulls basketball player, Michael Jordan. The Air Jordan line of<unk> s sold $100 million in their first year. As barefoot running became popular by the late 20th and early 21st century, many modern<unk>  manufacturers have recently designed footwear that mimic this experience, maintaining optimum flexibility and natural walking while also providing some degree of protection. Termed as Minimalist<unk> s, their purpose is to allow one's feet and legs to feel more subtly the impacts and forces involved in running, allowing finer adjustments in running style. Some of these<unk> s include the Vibram FiveFingers, Nike Free, and Saucony's Kinvara and Hattori. Mexican huaraches are also very simple running<unk> s, similar to the<unk> s worn by the Tarahumara people of northern Mexico, who are known for their distance running abilities. Wrestling<unk> s are also very light and flexible<unk> s that are designed to mimic bare feet while providing additional traction and protection. Many athletic<unk> s are designed with specific features for specific activities. One of these includes roller skates, which have metal or plastic wheels on the bottom specific for the sport of roller skating. Similarly, ice skates have a metal blade attached to the bottom for locomotion across ice. Skate<unk> s have also been designed to provide a comfortable, flexible and durable<unk>  for the sport of skateboarding. Climbing<unk> s are rubber-soled, tight-fitting<unk> s designed to fit in the small cracks and crevices for rock climbing. Cycling<unk> s are similarly designed with rubber soles and a tight fit, but also are equipped with a metal or plastic cleat to interface with clipless pedals, as well as a stiff sole to maximize power transfer and support the foot. Some<unk> s are made specifically to improve a person's ability to weight train. Sneakers that are a mix between an activity-centered and a more standard design have also been produced: examples include roller<unk> s, which feature wheels that can be used to roll on hard ground, and Soap<unk> s, which feature a hard plastic sole that can be used for grinding. Boot steel-toed safety boots A boot is a special type of<unk>  which covers the foot and the ankle and extends up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. They are typically made of leather or rubber, although they may be made from a variety of different materials. Boots are worn both for their functionality—protecting the foot and leg from water, snow, mud or hazards or providing additional ankle support for strenuous activities—as well as for reasons of style and fashion. Cowboy boots are a specific style of riding boot which combines function with fashion. They became popular among cowboys in the western United States during the 19th century. Traditional cowboy boots have a Cuban heel, rounded to pointed toe, high shaft, and, traditionally, no lacing. They are normally made from cowhide leather but may be made from more exotic skins such as ostrich, anaconda, or elephant skins. Hiking boots are designed to provide extra ankle and arch support, as well as extra padding for comfort during hiking. They are constructed to provide comfort for miles of walking over rough terrains, and protect the hiker's feet against water, mud, rocks, and other wilderness obstacles. These boots support the ankle to avoid twisting but do not restrict the ankle's movement too much. They are fairly stiff to support the foot. A properly fitted boot and/or friction-reducing patches applied to troublesome areas ensures protection against blisters and other discomforts associated with long hikes on rugged terrain. During wet or snowy weather, snow boots are worn to keep the foot warm and dry. They are typically made of rubber or other water-resistant material, have multiple layers of insulation, and a high heel to keep snow out. Boots may also be attached to snowshoes to increase the distribution of weight over a larger surface area for walking in snow. Ski boots are a specialized snow boot which are used in alpine or cross-country skiing and designed to provide a way to attach the skier to his/her skis using ski bindings. The ski/boot/binding combination is used to effectively transmit control inputs from the skier's legs to the snow. Ice skates are another specialized boot with a metal blade attached to the bottom which is used to propel the wearer across a sheet of ice. Inline skates are similar to ice skates but with a set of three to four wheels in lieu of the blade, which are designed to mimic ice skating on solid surfaces such as wood or
