The rear connecting body 42 grips and fixes the connecting tool adapter 24 of the snowboard boot 1 from the rear side. When releasing the lock, the grip portion 55 of the lock release lever 54 is swung to perform an operation reverse to the above operation. Since the upper surface 60 of the plate sole 30 is inclined with respect to the upper surface 62 of the snowboard 47 by an angle θ of 4 °, preferably 2-5 °, the rider wears the snowboard boot 1 on the snowboard 4
When placed on 7, the back of the foot is tilted at an angle θ with respect to the upper surface of the snowboard so that both knees are close to each other.

Therefore, to be precise, the plane including the surface 62 of the snowboard 47 and the axis of the foot are inclined forward (from the structure of the snowboard boot 1), and the angle θ is formed in the plane including the axes of both feet.
Only the knees are moved to the posture. Therefore, the posture of the foot can be kept in an ideal state.

(Other Embodiments) In the above embodiment, the snowboard boot 1 is tilted by the snowboard shoe tilting mechanism. However, the snowboard boot 1 is tilted in addition to the plate sole 30 and the connecting tool 21. A method of inclining with a spacer interposed may be used. Further, the snowboard side binding mechanism 40 may be tilted. For example, there are a method of changing the wall thickness of the base member 43 and inclining it, a method of interposing a spacer, and the like.
