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.
History
Track spikes had become popular in England by the 1860s, 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):
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. The company began distributing shoes across the United Kingdom and were worn by British athletes. 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.
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.
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. 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.
Design
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.
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 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.
Types of shoes
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.
