Spiked running shoes have been around for over 100 years created by the British company Reebok in the 1890's. The spiked shoe was developed out of necessity. The founder of the company enjoyed running and wanted to develop a shoe that would increase his speed.In 1925 a company called Adi Dassler now known as Adidas created a range of shoes with hand-forged spikes. They offered a range of shoes for different distances. The company used the strongest and lightest materials available at the time to make the running shoes. Adi Dassler's brother went on to found the Puma sports shoe company.The involvement of science and technology in the 1970's sports shoe manufacturers employed experts to conduct research into how humans run. They also investigated the shock effect to the body caused by the collision between the feet and the ground. Their finding helped to develop new, improved sports shoes.
Their research found three types of running styles:
Outer-sole: The outer-sole makes the wearer feeling comfortable and allows a natural instep. The natural rubber heels can be replaced by an ordinary heel.
Insole: Insoles can cushion feet comfortably and add additional height which is the magic part to increase height. It can be made from plastic, cork or foam. The front part is lower than the back part. There are different designs in the slope and curve to fit different feet.
Mid-insole: The mid-insole offers some level of buffer between insole and outer-insole. Because insole is usually made with soft and expensive material, it is easy to be worn out. The mid-insoles protect the deterioration of insoles and provide aeration.
Height increasing shoes look like ordinary shoes from outside because the heels are hidden. In fact the name of lift shoes, tall shoes, height increasing shoes and elevator shoes means the same kind of shoes. Height increasing shoes are attractive to those who desire to look taller immediately and effectively.

Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. The flexible type of polyurethane is used to make upholstery, mattresses, earplugs, chemical-resistant coatings, specialty adhesives and sealants, and packaging. It also comes to the rigid forms of insulation for buildings, water heaters, refrigerated transport, and commercial and residential refrigeration. It is used in the manufacture of sports shoes because of its lightweight shock absorption properties as well as being pliable as well as having great torsional and bending strength. Kevlar is one of the most important man-made organic fibres ever developed. The fibre possesses a remarkable combination of properties that has led to its use in a variety of commercial products since its invention in the 1970's. The fibres of Kevlar consist of long inter-connecting molecular chains produces from poly - paraphenylene terephthalamide. Kevlar offers high tensile strength with a low weight, structural rigidity, low electrical conductivity, high chemical resistance, low thermal shrinkage, excellent dimensional strength, high cut resistance, flame resistant and self extinguishing. Pretty versatile really!
Upper: The upper is designed to accommodate the thick insole. The slope between the face and the post is more than that of normal shoes, so the post curve is higher which prevents tripping.
It is these special four parts that guarantee wearers' height increasing and their comfort. Height increasing shoes are different from normal shoes, but they look like ordinary shoes from outside which makes you get taller without any other knows.
