    The Types of Running Shoes What do we mean when we mention sneaker? In the past, sneaker referred to a person who was yellow bellied. We did not know the word "sneaker" until 1917. In 1917, an American advertising agency, Henry Nelson McKinney offered this slogan for the shoes of Keds Corporation. From then on, the gym shoes and other things associated with them have gradually been called "sneakers". I needed a pair of sneakers and who can recommend for me? Certainly, people's physical fitness and their feet are totally distinct. Moreover, they play basketball in different ways. The world does not have a pair of "universal shoes". There are some shoes which are fit for others, but not you. If you want to find out the shoes that are suitable to you, you need to make more efforts. Of course, it does not mean that others' advices are useless. But at least before you ask questions, you must tell people your height, weight, location, and your ways of playing. You must illustrate the situations of the court. Then you can get best suggestions and buy your suitable shoes. Why are most high end basketball shoes not wearable? Basketball shoes are different with other sports shoes. In most occasions, we make basketball shoes' outsole on the basis of the infield's condition. Generally speaking, this kind of shoes has soft outsoles. Then shoes can grip the ground better. If you wear these shoes in the outfield, you certainly wear them down. So, before you complain these worn shoes, you should think whether you picked wrong shoes or fields. In fact, many sports brands have their shoes especially designed for outfield. For example, there are DRC outsole applied by Nike and adiwear used by ADI. We can not compare these shoes with those flaring sneakers. But at least they are wearable and players can wear them for a long time on the outfield. I have a pair of running shoes. It was elastic and soft when I bought them. However, a spell of time later, they were not so soft and elastic. Why is it? In fact, there are only two materials of insoles of sneakers. They are EVA and Phylon. Both of EVA and Phylon are foam. That is to say, we can find incalculable small holes in these two materials. These small holes in the material play nike 4.0 an important role in decreasing the oscillation. However, a period of time later, their resilience will become weak because of too much press. We can say we give the shoes more press. As nike 6.0 backpack for this flaw, many firms take some measures to deal with. They often set more materials to reduce the vibration. Then players can wear them for a longer time. Air cushion of Nike is a typical representative. If nike 8 vapor woven you are too weighty and very good at jumping, you had better not choose the shoes with only EVA midsoles. These shoes have weak cushioning and it can last several months or less. Maybe their outsoles and upper sides are in good condition. However, your feet and legs can not be guarded by this kind of sneakers. Therefore, after you understand the basic knowledge, you can get your comfortable and wearable running shoes. I wish the basic knowledge would be beneficial to you
