It is very expensive for a defender to wear shoes to play ball. Holding the ball to break through, change direction and make an emergency stop requires that the friction of the shoes should be enough and the players should push the ground. In this process, the shoes should give enough support to the feet, otherwise the players will slip, which is very dangerous. When pedaling, a player is very powerful, and many shoes will be deformed because of the friction on the ground and the stress on his feet.
A pair of good sneakers will last for a long time, which will protect the players' feet in actual combat and let them give full play to their abilities and win the game.

Each player's physical confrontation is excellent, of course, the strength of the lower limbs is also extremely exaggerated.
