The hardness of a golf ball is generally 70 ° - 105 °. The higher the degree, the harder the ball will be and the harder it is to master the direction. Beginners are suitable to choose a ball with lower hardness. The soles of golf shoes generally have about 6~7 soles, which can prevent slipping and keep the players in balance when swinging.

The rubber golf ball is initially solid, and then uses solid substance or liquid as the core. Modern golf balls are mostly made of liquid core and rubber shell. There are many regular "dimples" on the surface of the white rubber ball to facilitate flight and improve accuracy.
