The ground-breaking manufacturing technique that allowed the development of the plimsoll was called vulcanization
cheap asics gel, which is still used today. This process uses heat to meld rubber and cloth together. Sulfur is used during the process.Plimsolls were revolutionary at the time as they provided comfort, were lightweight and allowed the user to move around silently. Plimsolls became known as sneakers and were sold on a mass scale in America as early as 1917.In the four years since the last Olympics in Athens technology has moved on somewhat and has definitely moved on since the plimsoll days.Trainers and clothing has evolved to be lighter and stronger. But what part has technology had to play in enhancing the performance of our Olympians?Differing materials offer different properties such as stability; offering resistance to twisting and warping. When weight is applied to a material over a period of time it will creep (flatten out and spread).
