KEVLAR®
is one of the most important manmade organic fibres ever developed. Because of its unique combination of properties it is used today in a wide variety of industrial applications. The fibre possesses a remarkable combination of properties that has led to its use in a variety of commercial products since the 1970's.
Fibres of KEVLAR® consist of long, interconnecting molecular chains produced from poly-paraphenylene terephthalamide. Kevlar is 10 times the strength of leather.
Leather/canvas
This material is thin, stable and low density. A Kangaroo leather commonly used in football shoes because it gives a footballer that extra spring in his or her step and it offers good elasticity.
Compression-molded EVA
The most common insole material. EVA stands for ethylene vinyl acetate, a combination of two types of plastics. This material revolutionised the construction of sports shoes. It was made up of tiny air bubbles that provide cushioning and absorbs shock. This material is injection moulded into shapes, which serve as heel supports.
Polyurethane
Another type of material that behaves like plastic or rubber, and is used in midsoles. Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Polyurethane is not as commonly used as EVA because it tends to be heavier and firmer.
Carbon Rubber
Durable rubber compound that makes up the majority of running shoe outsoles.
Blown Rubber
Air-injected rubber that is lighter, softer and more flexible than traditional rubber. Blown rubber is most often found in the forefoot. It provides a great feel but is less durable than carbon rubber.
