The cleat position structure of the snowboard boot described above is formed symmetrically for the left and right feet. During exercise,
The left and right feet are inclined so that they approach each other. The centerline of rotation of the sloping snowboard boots is low relative to the bottom of the foot. The foot is an anteroposterior direction line passing through the sole of the foot or an anteroposterior direction line at a position slightly higher than the sole of the foot, which is the center line L.
The rotation center line K that is closer to the inside than (see FIGS. 1, 3, 5, 7
(Indicated inside) rotate and tilt.

The rotation of the ankle is not limited to the rotation around the eccentric rotation center line K, but includes the rotation around the center line L.
In any case, the lack of a rigid core in the outer portion greatly reduces the force or pressure with which the outer portion of the sole presses the sole.

This rotation center line K on both sides can be inclined inward in a direction toward the front with respect to the center line L. Inclining in this manner facilitates a motion of tilting both ankles in a forward leaning direction so as to face each other, that is, inward, or in a forward leaning direction in the traveling direction.

Irrespective of the direction of the rotation centerline K, the inward rotation of the ankle about the centerline of the cleat which is biased inward is easy and smooth. Such a rotation / tilt movement is easy even for an ankle that leans forward.
