ball do not move flat, but in the rotation, if the gloves
rough, large friction ball and glove, ball and glove rolling
contact occurs, change the direction of movement of the ball, the
goalkeeper is not easy to hold the ball.Smooth glove friction is small, you can keep the ball in the hands
of goalkeeper rotation without changing the direction of flight of
the ball, so that the goalkeeper is more easy to control the ball.Football opponents less impact, increasing the stability ball.In addition, palm glove with dense small particles, can also
increase friction and improve the stability ball.
