Motocross boots are designed specifically for off-road, motocross (MX) or all-terrain vehicle riding. To help prevent a rider’s feet and legs from being injured, motocross boots are typically much more stiff than regular motorcycle boots or racing boots, but are more flexible than ski boots by comparison.
Modern motocross boots are usually nearly knee-high (about 16 inches in height) and made from a combination of leather, metal, plastic and/or man-made composite materials to create a very form-fitting, comfortable and tight boot. To allow a rider to easily get the boot on or off, the shaft of a motocross boot is designed to open lengthwise. Multiple adjustable straps (usually 4 to 5) are deployed along the foot, ankle and shaft of the boot to allow the rider to tighten the boot to his/her preferences and comfort. Some manufacturers also include an internal quick-lacing system between a soft inner leg and the outer harder shell of the boot shaft to further ensure a tight, but comfortable fit. To protect the leading edge of the boot sole against rough terrain, a metal plate is usually screwed in place.
The heel of a motocross boot is typically very low: not more than 1/2-inch. A curved plastic or composite plate covers the shin of the boot to protect the rider from debris that may be thrown from the front wheel of the motorcycle. The most common colors of motocross boots are black or white, but other colors such as red, blue, yellow and green (possibly combined with black or white) are also available. Trick riders often opt to wear white boots as they are more most readily visible.
Similar to touring boots, racing boots are designed for riding a motorcycle on hard pavement (either the street or a race track) and are usually between 10 and 14 inches in height and made from a combination of leather, metal, plastic and/or man-made composite materials to create a form-fitting, but comfortable boot. 
The amount of armored protection provided by racing boots is usually greater than touring boots due to the increased potential for injury at the high speeds needed for racing.
Depending upon how form-fitting the boot is, to allow a rider to easily get the boot on or off, the shaft may be designed to open lengthwise. If so, Velcro is typically used on the inner sides of the opening to allow the rider to close the boot over the foot, ankle and leg. This allows for some flexibility for the rider to control the boot’s tightness. Some manufacturers also include an internal quick-lacing system between a soft inner leg and the harder outer shell of the boot shaft to further ensure a tight, but comfortable fit. The heel of a racing boot is typically very low: not more than 1/2-inch, and sole of the heel and foot is typically rather smooth. A curved plastic or composite plate may be included to cover the shin of the boot to protect the rider’s shin.
The most common color of racing boots is black, but other colors such as white, red, blue, yellow and green may be combined with black or each other in some fashion. Typical street riders may prefer all black, but racers may opt for a color combination that matches the rest of their motorcycle leathers, helmet and/or motorcycle.
Sneakers are footwear of flexible material, typically featuring a sole made of rubber. The upper part is made of leather or canvas. Sneakers were originally sporting apparel, but are today worn much more widely as casual footwear. They are now widely popular. Many children choose to wear sneakers to school because of their comfort and versatality.
Sneaker can also reffer to an athletic shoe such as basketball shoes, tennis shoes or cross trainers. These shoes are sport specific shoes worn for varrious sports. Popular brands include Nike, Saucony, Adidas, Reebok, New Balance, Converse, PUMA, Shaq, Asics, C1rca, Etnies, Skechers, Vans,
The British English equivalent of “sneaker” is “trainer” in its modern meaning; however, the traditional “sneaker” is closer to the British “plimsoll”. In some urban areas in the United States, the slang for sneakers is kicks. In Hiberno-English and Australian English the term is runners. In South African English the term used is takkies.
Sneakers have become an important part of hip hop culture since the 70s. Presently, numerous rappers sign million dollar deals with major brands such as Nike, Adidas or Puma to promote their shoes. Sneaker collectors, called “Sneakerheads”, use sneakers as fashionable items. Artistically-modified sneakers can sell for upwards of $500.
In the 1800′s a London Police Officer developed a rubber soled shoe in order to catch criminals in the act quietly, he called his invention “Sneakers”. The name derives from the fact that the rubber soles made the shoes noiseless. The term “sneaker” itself was also used in 1887 by Boston Journal of Education:
“It is only the harassed schoolmaster who can fully appreciate the pertinency of the name boys give to tennis shoes — sneakers.” The British English term “trainer” derives from “training shoe.”
Sneaker boots
Sneaker boots are a type of shoe that mimics the visual appearance of a traditional sneaker, but is equipped with a high heel. The heel makes it impossible to use them as anything but dress shoes.
Examples:
- In 1995 Cyd Jouny made a crossover between a basketball sneaker and a stiletto mule.
- Nobox, by Reebok an unsuccessful design in the mid-90′s.
- Moxy, by Cherry avenue
- Converse Chucks
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 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 last during 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 the foot 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
The outsole is the layer in direct contact with the ground. Dress shoes often have leather or resin rubber outsoles; casual or work-oriented shoes 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 cleated shoes 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 use different 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 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, 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.
Lateral/medial
The outside part of the shoe is referred to as the lateral and the inside facing part of the shoe is the medial. This can be in reference to either the outsole or the vamp.
