On the shell part 3 is further a pivotable Sleeve part 8 articulated. For receiving a foot 9 is one of the shell part 3 and Cuff part 8 covered liner 10 is provided.

A bowl base 11 forms an inner support surface 12 for the foot 9 and the inner shoe 10, respectively from, is designed as a shock and / or vibration damping rib composite part 13 and has ribs 15 formed on a surface 14 facing away from the support surface 12. These cover the surface 14 in the form of a rib grid 16, which by longitudinal ribs 17 and approximately at right angles to extending transverse ribs 18 (see Fig. 2) is formed. The appropriate dimensioning of the ribs 5 and their arrangement on the surface 14 cause an excellent shock and / or vibration damping design of the rib composite part 13th

In a front end portion 19 and a rear end portion 20 forms the rib composite part 13 mounting surfaces 21 for the support of heel elements 22, the over tension and Fastening arrangements 23 are mounted on the ribbed composite part 13 and footprints Train 24. The shell part 3 outstanding are the heel elements 22 in essentially a heel ball support region 25 and a forefoot support region 26 assigned and form with the shell part 3 protruding projections coupling extensions 27 for coupling pieces 28 a ski binding 29 or board bond or similar Hold-down devices. The footprints 24 of the heel elements 22 are generally formed non-slip and optionally with a wear-resistant layer 30th Provided. For correct adjustment of the heel elements 22 on the ribbed composite part 13 are provided in the ribbed composite part 13 positioning pins 31, which in the paragraph elements 22 arranged pin bores 32 cooperate.

The clamping and fastening arrangements 23 are formed by screw connections, according to which the heel elements 22 in bores 33 threaded screws, e.g. countersunk 34, which project from the footprint 24, the heel elements 22 protrude and are bolted to anchored in the shell part 3 threaded sleeves 35. Im shown Embodiment, the threaded sleeves 35 are fixedly connected to an anchor plate 36 which resting on the support surface 12 of the shell base 11, wherein the threaded sleeves 35 in recesses 37 of the rib composite part 13 protrude. This is an absolutely secure attachment between the heel element 22 and the ribbed composite part 13 is achieved and also Reaction forces via fastening devices, such as ski binding on the sports shoe 1 act, safely absorbed.

It is now better to refer to Fig. 2 - a view of the sports shoe from below - it is by the inventive design of the heel elements 22 now possible, the heel elements 22 form with the molded clamping and centering projections 40 so, that the fastening arrangement 23 in the heel element 22 with respect to a longitudinal central axis 41 of the shell is arranged centrally, whereas symmetry axes 42 of the molded Clamping and centering projections 40 offset by a distance 43 parallel. By Such a lateral offset by the distance 43, it is now possible, the force application point, approximately in the middle of a length 44 and on the longitudinal central axis 41 of the Shell 3 lies - assuming a centric arrangement of the ski binding on the ski - by this distance 43 from the median plane of the ski 45 in the direction of an inner edge 46 of the Shift shoe 45 in order to exert an increased pressure effect on the inner edge 46, which is known to improve the steering and handling.

In Figs. 3 and 4, the heel element 22 on the shell part 3 of the ski boot 2 for the front End region 19 shown. As already described in the preceding figures, the heel element is 22 via the internally arranged anchor plate 36 and the threaded sleeves 35th and countersunk screws 34 attached to the underside of the shell part 3. The paragraph element 22 is also opposite the shell part 3 in its end portion 19 by a bead-shaped Positioning approach 47, which includes the end portion 19 in regions centered. A base plate 48 of the heel element 22 is formed symmetrically with respect to the longitudinal central axis 41, as well as with respect to the longitudinal center axis 41, the holes 33 for the countersunk screws 34 are arranged symmetrically.

On the base member 48 is integral and the positioning lug 47 in the direction of the longitudinal extent the shell part 3 of the clamping and centering projection 40 is formed. The footprint 24 of the paragraph element 22 extends in the direction of an end face 49 of the clamping and Centering projection 40 chamfered to achieve an exemption and a rolling motion to allow when walking with the ski boot 2.

The clamping and centering projection is relative to the base member 48 by the distance 43 to Longitudinal axis 41 offset in the direction of an outer surface 50 of the shell part 3, whose Wall part 51 long an inner side 52 of the foot 9 extends.

By this lateral displacement towards the inside 52 of the foot 9 is an eccentricity achieved by tightening the ski boot in a ski binding, which makes the natural V-position of the feet can be maintained and an unnatural attitude during the Skiing is avoided.

In FIGS. 5 and 6, the further heel element 22, which is in the heel-side end region, is now shown 20 attached to the shell part 3 is shown. To achieve an optionally desired larger V-position of the feet is in this paragraph element 22 also the tension and Centering projection 40 on the base member 48 with respect to the longitudinal center axis of the shell part arranged eccentrically extending, wherein in the illustrated embodiment, a centering axis 53 to the longitudinal central axis 41 at an angle 54 and an intersection 55 of the centering axis 53 formed with the longitudinal center axis 41 within the formed by the paragraph 22 element Contact area 24 is arranged. The clamping and centering projection 40 is to the angle 54 in the heel side arranged paragraph element 22 in the direction of a Outside of the foot supporting wall portion 57 is provided.

In Fig. 7 is now in a schematic representation, which is characterized by an eccentric arrangement the clamping and centering projections 40 of the heel elements 22 resulting, possible Position of the ski boot 2 on the ski 45, when using a standard and Standard mounted ski binding 29, shown. The ski binding 29 is on the ski 45 positioned symmetrically with respect to a central axis 58 of the ski 45.

As can now be seen from FIG. 7, the arrangement of the coupling extensions 27 is at the opposite end End portions 19, 20 of the shell part 3 attached paragraph elements 22 chosen so that the axis of symmetry 42 formed by these in the angle 54 to the longitudinal central axis 41 of the shell part 3 extends. If the ski boot 2 is tensioned in the ski binding 29, results in a congruent position of the axis of symmetry 42 with the central axis 58 of the Schis 45 and thus an angular position of the ski boot 2 on ski 45. In Ausreührungsbeispiel shown the angular position is chosen so that the ski boot 2 with his heel side End portion 20 closer to the inner edge 46 on the ski 45 is arranged. By choosing the distance 43 and the angle 53 - eccentricity of the coupling extensions 27 - can the relative Position of the longitudinal central axis 41 of the shell part 3, with respect to the central axis 58 of the ski 45, are set, whereby the intersection 51 in which the longitudinal central axis 41 of Shell part 3 and central axis 58 of the ski 45 cut and in the direction of Längserstrekkung of the ski 45 can be varied. Since this intersection 51 is decisive for the introduction of the applied torque for controlling the ski 45 is influenced Position of the intersection 51 the driving characteristics or the situation to desired driving characteristics be adjusted. The point of intersection 51 can be within a distance 59 between coupling parts 60, 61 of the ski binding 29, but also outside this distance 59, i.e. in front of a toe piece 62 or behind a heel piece 63.

8 and 9, another embodiment of the paragraph element 22 is shown in which a the coupling extension 40 forming adjusting element 64 on the base member 48 adjustable, in pivoted shown embodiment, is arranged. The base member 48 is by means of the countersunk screws 34 and the anchor plate 36 attached to the shell part 3. With preferred two of the countersunk screws 34, the actuator 64 mitbefestigt, which in an in the contact surface 24 in the end-side end region of the base member 48 arranged recess 65 overlaps the base member 48. Furthermore, the actuator 64 is on the base member 48 by means of a bolt connection 66, a perpendicular to the footprint 24 extending Swivel axis 67 forms, pivotally connected, wherein the pivot axis 67, the longitudinal center axis 41 approximately in the region of the further spaced from the end face 49 countersunk screws 34 cuts. The end face 49 of the base element is curved in a circular arc, wherein a center 68 is located on the pivot axis 67. Facing the end face 49, the adjusting element 64 has a contact surface 69 designed to be the same as this on, which is surmounted by a guide extension 70 in the direction of the base member 48 and in a guide groove 71 which is arranged in the end face 49, engages. Through this education, with the guide groove 70 engaging in the guide groove 71, vertical forces, according to an arrow 72, which act on the coupling extension 27 when using the ski 45, received in the immediate area of action and thus the mounting arrangement and the bolt connection 66 relieved.

This embodiment of the heel element 22 with the actuator 64 now allows in one by circular arcuate elongated holes 73, in which the actuator 64 of the Countersunk screws 34 is penetrated, given pivoting range, a setting of Stellelementes 64 in the angle 54 between the longitudinal central axis 41 and the axis of symmetry 42 and thus the arrangement of the ski boots 2 in a V-position on the skis.

To adjust the angle 54, the countersunk screws 34, with which the actuator 64 is fastened, loosened and tightened after setting the desired angle 54, thus ensuring the proper power transmission and fixing the angular position is.
