Abstract: The invention refers to a ski boot, on the outside and in longitudinal direction of an insole 2 comprising a pair of L-shaped guides 5, 6 into which outsoles 7, 10 are inserted. Between the insole 2 and the outsoles 7, 10 there is arranged, preferably glued, a rubber dampening plate 20 which is at its both end parts provided with extensions 21, 22 perpendicular thereto. The outsoles 7, 10 are joined with the insole 2 in a manner that inbetween in the area of the midlength there is provided a space into which a rubber extension 19 is slitlessly inserted perpendicularly to the sole of the boot. In longitudinal direction of the ski boot the semicircular toe part of the outsole 7 and the semicircular heel part of the outsole 10 are spaced from each guide 5, 6 whereby in these spacings there are slitlessly arranged rubber dampening extensions 23, 24, 25, 26 which are aligned with the plane of the outer surface of the second leg of each guide 5,6.
