Sports equipment such as clothing and footwear needs to be user-friendly and include valuable properties such as strength, flexibility, toughness, resistance to moisture and more importantly cost. Footwear is generally chosen more for comfort and injury avoidance rather than performance enhancement, whereas clothing such as the full body suits used in cycling may be justified in activities where winning or losing is measured in hundredths of a second. Sporting equipment such as the composite tennis racket has been created in order to provide increased ball speed, and reduce the potential for injuries at the elbow joint. In golf, the overall mass of the club has decreased which is believed to result in a greater achievable distance and possibly a more accurate shot.
