The company was started by Adolf Dassler in his mother’s house; he was joined by his elder brother Rudolf in 1924 under the name Dassler Brothers Shoe Factory. Dassler assisted in the development of spiked running shoes (spikes) for multiple athletic events. To enhance the quality of spiked athletic footwear, he transitioned from a previous model of heavy metal spikes to utilising canvas and rubber. Dassler persuaded U.S. sprinter Jesse Owens to use his handmade spikes at the 1936 Summer Olympics. In 1949, following a breakdown in the relationship between the brothers, Adolf created Adidas, and Rudolf established Puma, which became Adidas’ business rival.^[1]

Adidas’ logo is three stripes, which is used on the company’s clothing and shoe designs as a marketing aid. The branding, which Adidas bought in 1952 from Finnish sports company Karhu Sports, became so successful that Dassler described Adidas as “The three stripes company“.^[7][8][9] The brand name is uncapitalized and is stylized with a lower case “a”

Running shoes are made from a combination of materials. The sole has three layers: insole, midsole, and outsole. The insole is a thin layer of man-made ethylene vinyl acetate (EVA). The components of the midsole, which provides the bulk of the cushioning, will vary among manufacturers. Generally it consists of polyurethane surrounding another material such as gel or liquid silicone, or polyurethane foam given a special brand name by the manufacturer. In some cases the polyurethane may surround capsules of compressed air. Outsoles are usually made of carbon rubber, which is hard, or blown rubber, a softer type, although manufacturers use an assortment of materials to produce different textures on the outsole.

The rest of the covering is usually a synthetic material such as artificial suede or a nylon weave with plastic slabs or boards supporting the shape. There may be a leather overlay or nylon overlay with leather attachments. Cloth is usually limited to the laces fitted through plastic eyelets, and nails have given way to an adhesive known as cement lasting that bonds the various components together.

Design

The last 15 years have witnessed great changes in the design of the running shoe, which now comes in all styles and colors. Contemporary shoe designers focus on the anatomy and the movement of the foot. Using video cameras and computers, they analyze such factors as limb movement, the effect of different terrains on impact, and foot position on impact. Runners are labeled pronators if their feet roll inward or supinators if their feet roll to the outside. Along with pressure points, friction patterns, and force of impact, this information is fed into computers which calculate how best to accommodate these conditions. Designers next test and develop prototypes based on their studies of joggers and professional runners, readying a final design for mass production.

A running shoe may have as many as 20 parts to it, and the components listed below are the most basic. The shoe has two main parts: the upper, which covers the top and sides of the foot, and the bottom part, which makes contact with the surface.

As we work our way around the shoe clockwise, starting at the front on the upper part is the featherline, which forms the edge where the mudguard (or toeguard) tip meets the bottom of the shoe. Next is the vamp, usually a single piece of material that gives shape to the shoe and forms the toe box. The vamp also has attachments such as the throat, which contains the eyestay and lacing section. Beneath the lacing section is the tongue, protecting the foot from direct contact with the laces. Also attached to the vamp along the sides of the shoe are reinforcements. If sewn on the outside of the shoe these reinforcements are called asaddle; if sewn on the inside, they are called an arch bandage. Further towards the back of the shoe is the collar, which usually has an Achilles tendon protector at the top back of the shoe. The foxing shapes the rear end of the shoe. Underneath it is a plastic cup that supports the heel, the heel counter.
