Sporting goods are used for recreational activities, sports, and exercise. They can be used in everyday life whether one is in the water, on the ground, or even in the air. Equipment includes various objects related to the particular sport. For example in tennis, consumers need a raquet and ball to play the game, while to play soccer one needs to purchase cleats and a ball. Depending on the sport different equipment is needed. The three most popular sports are baseball, football, and basketball. When signing up for these activities, whether it is for ones children, school athletics, or an adult league, one must buy the appropriate equipment to play or it could result in injury, like a torn muscle. The most important object players should purchase is footwear. There are shoes specifically designed for every sport such as tennis and basketball shoes, and baseball and football cleats. They are designed to keep the foot firm inside and to protect the ankle, so one can perform at a high level and keep their grip and not slip. Consumers can buy shoes and other equipment at sporting good stores. Water sporting goods include kayaks, surfboards, and water polo accessories. These activities depend on where one lives, because water is needed. Air accessories can include parachutes and pedometer watches, but these are found normally in specialty stores. Consumers can purchase most of these goods at local Big 5, Sports Authority, and Dick's Sporting Good stores.
