All exercise clothing should be loose-fitting to permit freedom of movement, and should make the wearer feel comfortable and self-assured.
As a general rule, you should wear lighter clothes than temperatures might indicate. Exercise generates great amounts of body heat. Light-colored clothing that reflects the sun's rays is cooler.
Its a good idea to wear something on your head. Some form of tennis or sailor's hat that provides shade and can be soaked in water is good for hot and sunny days.
Never wear rubberized or plastic clothing, such garments interfere with the evaporation of perspiration and can cause body temperature to rise to dangerous levels.
The most important item of equipment for the runner is a pair of sturdy, properly-fitting running shoes. Training shoes with heavy, cushioned soles and arch supports are preferable to flimsy sneakers and light racing flats.
