A special running shoe is essential for anyone who is going to run long distances. The proper shoe will provide cushioning for the foot and leg, and support to the feet.
Every sport places a different type of stress on the foot and leg.
The proper shoe for another sport is inappropriate for running, just as a running shoe should not be used when participating in other sports. For example, tennis shoes and basketball sneakers are inadequate for running because they offer no cushioning for support. In contrast, wearing running shoes for other sports may lead to an increased risk of ankle sprain. Each foot of the runner hits the ground at an estimated 800 times during every mile of running. The forces generated are about five times the body weight and must be absorbed and distributed evenly, enabling the runner to continue with- out putting undue stress on any one area of the body.
