We do not know whether the messenger wore sandals, when he ran the first forty-two kilometres to warn the Greeks of an impending invasion. The history of running shoes development began with his epic race. The fact that he died after giving his news is proof of how much strain running can put on the body. Some people still argue that it is better not to wear shoes for running. In fact, Zulu soldiers were forced to toughen their feet by stamping thorns into the ground. In this way they were able to acquire permanent pumps because the soles of their feet were thick layers of hide that could carry them over rough ground without injury or pain. While this was happening in Africa a man called Walt Webster thought of sticking a layer of rubber to the bottom of nike free serials shoes. They were intended for tennis but thieves found them useful for sneaking about, so they were called sneakers. More than a century later this type of shoe was still being used for running long distance marathons.
The man who really started everything was Adolf Dassler. He prepared shoes for the 1936 Olympic Games, now known as 'Hitler's Games.' They were popular, but forgotten in the heat of war. After the war, conditions had changed. Dassler had to use scraps of rubber nike free run shoes. He devised the idea of putting three strips of leather across the top of each shoe to strengthen it. In the post modern period jogging took off as a leisure activity. It kept the blood moving, and was cheap and easy way to maintain a healthy lifestyle. Thousand of feet pounding the ground every day meant that new purchases had to be made not only for new entrants to running clubs, but also for replacements. The demand for leisure footwear created a big new industry. With the growth of the industry new materials were developed. They enabled feet to breathe as air was admitted around the foot through light mesh materials that were as strong as silk, and just as flexible. Hard rubber soles allowed for more durability, and support for ankles was built into the designs.
The large numbers of athletes nike free 3.0 demanding new improvements in sporting footwear stimulated sports science. Detailed analysis of exactly how people run, striking the ground with one foot at a time gave even more impetus to the production of new designs. Some ankles turn in, and some turn out. The many thousands of times that this happens creates patterns of wear which can be noted by experts who will recommend appropriate new purchases. So the industry became increasingly sophisticated. As the road running industry matured, so some problems became evident. Over time hip and knee injuries developed and designers had to respond to these problems. They developed new kinds of cushioning to soften the blows of feet striking the ground continually. Some examples had bubbles of gel built into the sole, so that a bouncing sensation was created.As jogging has taken hold as a popular pastime among women the history of running shoe development has taken another turn for the better. Light pastel uppers and coloured soles now flicker along the roads, adding glamour and fashion to performances that have improved dramatically in the case of female athletes.
