Track spikes, or just spikes, are a type of footwear featuring protruding spikes on the soles used by athletes when racing on the track. Some spikes are designed for longer-term training on tracks, but generally the shoes are used for racing. The term "spikes" can also refer to track shoes featuring such protrusions, though these are technically called pins. Spikes are similar to studs, which are used for team sports, although generally smaller and with a sharp point.
Track spikes had become popular in England by the 1860s, [1] but the concept of spikes in shoes to give running traction has been around much longer. As written in the 1852 publication of Calmet's Dictionary of the Holy Bible regarding military arms at the time of Paul the Apostle (c. 5 – c. 67):
"Having the feet shod with the preparation of the gospel of peace;" not iron, not steel; but patient investigation, calm inquiry; assiduous, laborious, lasting; if not, rather, with firm footing in the gospel of peace. Whether the apostle here means stout, well-tanned leather, leather well prepared, by his "preparation of the gospel of peace" or shoes which had spikes in them, which, running into the ground, gave a steadfastness to the soldier who wore them, may come under remark hereafter. We shall only add, that Moses seems, at least according to our rendering, to have some allusion to shoes, either plated, or spiked, on the sole, when he says, (Deut. xxxiii. 25.) "Thy shoes shall be iron and brass; and as thy days shall thy strength be." [2]
For pioneering the use of spikes, J.W. Foster and Sons's revolutionary running pumps appear in the book, Golden Kicks: The Shoes that changed Sport. [3] The company began distributing shoes across the United Kingdom and were worn by British athletes. [3] They were made famous by 100m Olympic champion Harold Abrahams (who would be immortalized in the Oscar winning film Chariots of Fire ) in the 1924 Summer Olympics held in Paris. [3] [4]
In 1934, American football player and coach Pop Warner recommended them for running events in his widely distributed book, "Pop" Warner's book for boys. [5]
Additionally, Adolf Dassler, the founder of Adidas, assisted in the development of track spikes for multiple events. In an effort to enhance the quality of spiked athletic footwear, he transitioned from a previous model of heavy metal spikes to attempting to utilize canvas and rubber. [6] He carved them by hand and were eventually worn during the 1936 Olympics by Jesse Owens. People began to take notice, and Owens inherently helped popularize Dassler's design. Track spikes continued to gain notable recognition when Emil Zátopek, a distance runner from Czech Republic, wore them during the 1952 Olympics in Helsinki. [7]
The front of the sole features a rigid or semi-rigid spike plate containing between 3 and 9 threaded holes called spike wells. Spikes can be screwed into each well using a spike wrench. Recently, some individuals have attempted to add a "through hole" at the bottom of the spike to make them easier to tighten, remove, and install. [8]
Some shoes have permanent or "fixed" spikes which are not meant to be removed. Spikes may break during competition.
Track shoes are exceptionally light, some shoes weighing less than five ounces (140 grams) each, half the weight of many standard running shoes.
In most track shoes, the toe region bends up to allow space for protruding spikes and to encourage athletes to run on their toes. This upward angle, known as "taper," varies widely depending on the intended use of the shoe, and the taper angle can be rigid or flexible. Shoes with a large taper are said to be "aggressive."
This shoe design may cause harm to the athlete if worn for extended periods of time outside of competition. Injury may occur when walking in a leisurely fashion, as the athlete is not on his or her toes, which is the manner in which the shoes were meant to be worn. [9]
There is considerable variation among track shoes depending on their intended use within the sport of track and field.
Sprint spikes generally have a very stiff spike plate with the greatest number of spike wells. The taper is highest and most rigid in sprint spikes, maximizing the efficiency of energy transfer with each stride. Very little heel support is needed because sprinters spend most or all of their time on their toes. Sprint spikes may have a zip-up cover instead of or in addition to laces to improve aerodynamics. Sprint spikes should fit tightly but they should not be too tight to the point that the runners toes are cramping and they should not be too loose that will result in the runner losing power and speed. They should fit tighter than regular athletic shoes yet still comfortable enough to perform in.
Distance shoes have a more flexible spike plate with less taper and fewer spikes. Because of the longer race distances, support through the mid-foot and heel is as important as efficiency with distance spikes. This means that distance spikes generally have a softer, more durable sole, particularly through the heel region. Although still "glove-like," the fit for distance spikes is generally slightly looser than for sprint spikes, given the longer race duration.
Middle distance spikes are a hybrid of a sprint shoe and a distance shoe, featuring an intermediate level of taper, spike plate rigidity, cushioning and support. Certain middle distance spikes are also popular among hurdlers because they have a relatively steep taper for sprinting and a cushioned heel for landings.
Cross country spikes usually have no more than six spike points and are similar to distance spikes in many respects. However, given the wide range of terrain encountered off-track, cross country spikes have a more durable rubber sole and supportive mid-foot to provide a level of cushioning and stabilization not required on a track. Depending on race length, surface types and personal preference, cross country spikes may be abandoned in favor of racing flats.
Shoes for field events and specialty events vary widely depending upon the specific requirements of each event. For example, long jump shoes are most similar to sprint spikes to provide good top speed, high jump shoes have flat bottoms and heel spikes to allow energy transfer through the entire foot, and steeplechase shoes are predominantly a water-resistant mesh for exceptional ventilation. While shoes for shot put, discus and hammer throw have flat rubber soles with no spikes, they may still occasionally be referred to as "track spikes."
Notable spike manufacturers include Adidas, Asics, Brooks, Mizuno, New Balance, Nike, Puma AG, Reebok and Saucony.
While most spikes are between 3⁄16 inch (4.8 mm) and 1⁄2 inch (13 mm) long, the most common is 1⁄4 inch (6.4 mm). Additionally, there are various specialty lengths, as well as minimal "blank" spikes (also called studs) used to cover a spike well. Spikes are generally metal or ceramic and come in three main types: the pyramid, the needle (pin), and the compression tier (Christmas tree). Pyramids are conical spikes that taper to a sharp point. They normally have a maximum diameter nearly equal to the diameter of the threads of the spike. Needles also have a sharp point, but a thinner cone diameter. Track spikes create traction by penetrating the track surface. Some tracks do not allow pin spikes and limit the length of pyramid spikes to minimize damage to the track. A variation for synthetic tracks is the Christmas Tree spike. It uses a terraced cone shape with a flat end designed to compress rather than penetrate the track below it. However, the notion that the compression spikes have less track penetration is not supported by scientific studies. [10] Lastly, there are Tartan spikes that are dull that are most commonly used for rubber tracks.
The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
Running is a method of terrestrial locomotion by which humans and other animals move rapidly on foot. Running is a gait with an aerial phase in which all feet are above the ground. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to sprinting.
A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function, but over time, shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.
Ice skates are metal blades attached underfoot and used to propel the bearer across a sheet of ice while ice skating.
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.
A boot is a type of footwear. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend 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. Traditionally made of leather or rubber, modern boots are made from a variety of materials.
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on bearings with respect to the spindle.
A climbing shoe is a specialized type of footwear designed for rock climbing. Typical climbing shoes have a tight fit, an asymmetrical downturn, and a sticky rubber sole with an extended rubber rand to the heel and the toe. Different types of shoes can be better suited for different levels of technique and routes.
Sneakers (US) or trainers (UK), also known by a wide variety of other names, are shoes primarily designed for sports or other forms of physical exercise but which are also widely used for everyday casual wear.
Sandals are an open type of shoe, consisting of a sole held to the wearer's foot by straps going over the instep and around the ankle. Sandals can also have a heel. While the distinction between sandals and other types of footwear can sometimes be blurry, the common understanding is that a sandal leaves all or most of the foot exposed. People may choose to wear sandals for several reasons, among them comfort in warm weather, economy, and as a fashion choice. Usually, people wear sandals in warmer climates or during warmer parts of the year in order to keep their feet cool and dry. The risk of developing athlete's foot is lower than with enclosed shoes, and the wearing of sandals may be part of the treatment regimen for such an infection.
Hiking (walking) boots are footwear specifically designed for protecting the feet and ankles during outdoor walking activities such as hiking. They are one of the most important items of hiking gear since their quality and durability can determine a hiker's ability to walk long distances without injury. Hiking boots are constructed to provide comfort for walking considerable distances over rough terrain. Boots that protect the hiker's feet and heel are recommended. Hiking boots give ankle support and are fairly stiff. A less popular alternative is to use light trainers with thin soles. Footwear should be neither too loose nor too tight, to help prevent blisters and sore feet. Hiking socks that wick sweat from the feet, provide warmth, and cushion the feet are recommended and a thin, inner sock may also help. Most hiking boots are also designed for other outdoor activities such as backpacking, climbing, mountaineering, and hunting.
Skate shoes or skateboard shoes are a type of footwear specifically designed and manufactured for use in skateboarding. While numerous non-skaters choose to wear skate shoes as they are popular in fashion, the design of the skate shoe includes many features designed especially for use in skateboarding, including a vulcanized rubber or polyurethane sole with minimal tread pattern or no pattern, a composition leather or suede upper, and reinforced stitching to extend the life of the upper material. The most important aspect of skate shoes is that they have flat soles which allow the skater to have better board control.
Chuck Taylor All-Stars or Converse All Stars are sneakers manufactured by American fashion brand Converse. Initially developed as a basketball shoe in the early 20th century, its design has remained largely unchanged since its introduction. The shoe consists of a stitched upper portion, and a toe cap and outsole usually made of rubber. Although Chuck Taylors are made of various materials such as leather or suede, the original and most widely known version is made from cotton canvas. The innovative detail of the original shoe was the "loose lining" of soft canvas that was intended to provide flexibility and prevent blisters.
Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. Key features include rigidity, for more-efficient transfer of power from the cyclist to the pedals, weight, a method of attaching the shoe firmly to the pedal and adaptability for use on and off the bicycle. Most high-performance cycling shoes can be adjusted while in use, via a quick-adjusting system that has largely replaced laces.
A dress shoe is a shoe to be worn at smart casual or more formal events. A dress shoe is typically contrasted to an athletic shoe.
Racing flats, or simply flats, are lightweight athletic shoes designed for "long distance" track and field, cross country, and most often, road races. They differ from normal training shoes mainly by the lack of a substantial heel to toe drop.
Jika-tabi are a style of footwear with a divided toe, originating in Japan. They are similar to tabi socks in both appearance and construction. Though they can be worn with traditional thonged footwear such as geta and zōri, jika-tabi are mostly designed and made to be worn alone as outdoor footwear, resembling boots that reach roughly to the mid-calf. Jika-tabi are also known as 'tabi boots'.
Cleats or studs are protrusions on the sole of a shoe or on an external attachment to a shoe that provide additional traction on a soft or slippery surface. They can be conical or blade-like in shape and can be made of plastic, rubber or metal. The type worn depends on the environment of play: grass, ice, artificial turf, or other grounds.
Cross country running shoes are made for cross country running, a form of long distance running. Season-specific trainers are available for different types of training.
In 2017, Nike released the Nike Zoom Vaporfly Elite shoe, which was advertised as "ultra-lightweight, soft and capable of providing up to 85-percent energy return." These "super shoes" became the focus of claims that they were a form of technology doping and that they provided athletes an unfair advantage.
