Claim:
A ski binding device, in which a ski boot ( 4 ) is connected to a ski ( 2 ) at its toe portion ( 6 ) comprising a guide ( 1 ) having a first guide portion extending upwardly from the ski ( 2 ) and a second guide portion having a height greater than a width to co-operate with the first guide portion, wherein the second guide portion is attached to the ski boot ( 4 ) on a rearward facing surface of the boot at its heel portion ( 18 ), wherein mutual guiding surfaces of the first guide portion and the second guide portion are adjacently arranged so as to transfer torque ( 16 ) around a longitudinal axis of a sole of the ski boot ( 4 ) to the ski ( 2 ) as torque around the longitudinal axis of the ski ( 2 ) when the ski boot is rotated about its own longitudinal axis whereby the boot and the ski rotate together about their longitudinal axes and also rotate together when the heel portion ( 18 ) is at a distance from the ski.
