The height of the right and left inside end is made greater than the height of the outside end for the direction of travel of the grass skis 1, and the height of the inside end of the respective grass skis 1 is made greater than the height of the outside end. The step base 3a is arranged behind the center in the forward and backward directions of the grass ski 1.;COPYRIGHT: (C)2014,JPO&INPIT
