Abstract

The invention relates to a winter sports shoe (11) and a winter sports shoe/ski combination. The winter sports shoe is characterized in that the front part (29) of the outer shoe (13) is largely decoupled with a modest exertion of force from the rear part of the outer shoe (13) by means of a flexible transitional area provided in the metatarsal area (19) so that when engaging in sport or when walking, the front part (29) is permitted, in the area of the ball of the foot, to pivot around or slide off on an axis (32) that is transversal to the longitudinal extension of the shoe (11). In addition, the outer shoe leg (21) and the lateral walls (25a, 25b) extending up to the transitional area are constructed such that they are essentially inflexible so that a force can be exerted via the outer shoe leg (21) onto the metatarsal area (19) of the sole (17).

Description

Technical field of the invention

The present invention relates to a winter sports shoe according to the preamble of claim 1 and a ski and shoe system according to claim 33.

State of the art

The not always selfless endeavor of the sports industry, the Athletes the optimal material for practicing the respective sport (Sports equipment, shoes, clothing) has made that the cabinets of sports enthusiasts often overflow with the various, needed sports shoes and clothing. This development also has before Winter sports did not stop where for various sports such as skiing, Tourschiwandern, carving, snowboarding each different sports equipment, Bindings, shoes and sometimes clothing are propagated.

The most recent development in alpine skiing is the term "carving" known. By this one understands a departure technique, with which under Use only a so-called "carving ski" (= a short ski with Taillierung) by tilting the ski smaller or larger curve radii driven become. The curve radii are significantly influenced by the Waist of the ski, which is expressed by radius. At the carving ski the radius varies between about 12 to 27 m.

Carving ski bindings are compatible with conventional safety bindings in alpine sports comparable, but with the difference that carving-Schibindungen Have spacer, so that the sole of the ski boot in distance to Schioberfläche is. Due to the increased arrangement of the ski boot on the ski it makes possible, through the associated increased leverage even tighter Radii to drive.

It is well known that the skis partially when cornering bend. Here are the forces acting on the elastically deformable ski Forces, the greater the closer a curve is to be driven.

By the experiences made in ski racing one knows today that one Stiffening of the ski in the binding area negatively affects the driving behavior in Affects curves. In particular, a stiffening of the ski area, that more is done with a swing and at the same time speed is lost. The The reason for the stiffening of the Schimittelbereich are those on the skis mounted ski bindings. Ski bindings that are one continuous Binding plate on which the binding front part and Binding back mounted, cause a stiffening of the ski over a Range of 30 cm and more.

Although a known carving ski binding has a continuous Binding plate on, but this binding plate is only in the middle area through two screws arranged at a distance of approx. 12 cm each with the ski undetachably connected, so that the ski is as little as possible stiffened. It is also the underside of the binding plate in longitudinal section arcuate (convex) formed so that the binding plate the bending of the ski outside of the Mounting area not limited when cornering.

With the known material (ski binding, ski boot), it is not possible that the rider actively influences the bend of the ski and the bend in the ski Curved used.

The shell-ski shoes used today have as characteristic Characteristic that by a constriction or volume reduction of a Hard plastic existing shell of the foot resp. the leg of the shoe wearer in Shoe is fixed. The shaft of the shell has a broad tongue, which as Extension of the outer shaft side wall is formed and around the Shin resp. puts the liner. On the other side of the shaft (inside) are formed in an analogous manner, two lobes, arranged at the ends of buckles are. The buckles can with corresponding, stationary parts at the Schuhaussenseite cooperate such that realized clamping and locking means are. Tongue and lobes together form an overlap area, whereby Tightening the lobes narrows the diameter of the shaft. A disadvantage of this well-known footwear is that pressure points are caused on the tibia.

WO-A-91/16957 (D1) relates to improved equipment consisting of Ski, bind and ski boot. The ski boot has a front part with a front sole and an upper front shell for receiving the foot part and a front Rear part with a rear sole and upper rear shell for receiving the Foot rear part. Front and back sole parts together define the Ski boot sole, with front and rear sole parts in the foot ball area relatively are flexible to each other. Ski boot front is in a front tie and Ski boot rear part is detachably received in a rear binding. Between front binding and rear binding a Fulcrum element is provided which on a movement of the sole front and rear parts reacts such that a Bending force on the central area is exercisable. According to WO-A-91/16957 only the combination of a ski boot with flexible sole with a Fulcrum element of importance. The shaft of the ski boots shown is well known and articulated commonly in the ankle area. When pressure is applied by the shin can therefore pivot the shaft forward to a certain extent.

US 5,746,016 discloses a ski boot with a pivotable toe cap and a likewise pivotable shaft. The toe cap should while running be mobile, but keep the foot essentially rigid while skiing. To For this purpose, the shell has a transverse recess on the instep. which is closed by a lid, so no dirt or snow can penetrate. On the lid, a tongue is formed, which is under the shell extends. With the help of an adjustable, with a spring biased bolt can The tongue can be blocked, so that a pivoting of the toe cap is impossible. The latter setting is the normal position set during skiing. Furthermore a Bowden cable is provided, with which the bolt is actuated. The Bowden cable connects the movable latch with an operating lever provided on the shaft. The operating lever has the additional function of the shaft and the toe cap to lock at the same time. This means that an immovable toe part with a immovable shaft are combined.

DE-OS-33 43 077 discloses a sole for a sports shoe, e.g. Ski boot, which becomes resistant to bending, pressure and torsion when acting from the outside force. Further the upper part of the shoe should be designed so that an introduction of force from Lower leg over the shaft, ankle and heel area is ensured in the ski. DE-OS 33 43 077 discloses with respect to design of the upper part no concrete technical characteristics, and shows a ski boot even in a schematic Presentation.

WO-A-99/10054 (D4) shows a shoe with a substantially flexible Shoe upper, which is connected to a two-part, stiff sole. The Sole parts are articulated in the area of the ball of the foot by means of a joint connected. Detecting means, e.g. in the form of one or more pens, allow the to lock both sole parts in a flat position. The locked, flat Sole position is chosen when the shoe is in a known ski binding should be included.

Object of the invention

It is an object of the present invention a ski boot, in particular all-round ski boot, which can be used for various sports such as skiing, Tourschiwandern, Carven, Snowbladen, Telemarken (Telemark skis), Snowboarding etc. can be used. Another goal is that the ski boot has a high Comfort has both while practicing the sport and afterwards. Another goal is to provide a shoe that is especially suitable for walking. Yet another goal is to provide a low cost ski boot. It is also the goal to propose a shoe and a binding system with which the bend of a Schis can be actively influenced. Also, the winter sports shoe at the Exercising the respective winter sports help to lessen the strain on the knees.

Description of the invention

According to the invention, a shoe according to the preamble of claim 1 is characterized marked that the outer shoe shank (21) and the side walls to the flexible resp. flexible transition area unyielding are formed such that by means of the outer shoe shaft (21) a Force is exercisable on the metatarsal area of the sole. The inventive Shoe allowed when the shoe is clamped in front and back in a ski binding is, by pushing the shaft forward, the sole of the ski shoe down to bend and thus exert a force perpendicular to the ski. These Property can be exploited for skiing. The fact that the Sole can be pushed down, has the advantage that the Body centerline can remain in the same place while skiing, since the Body automatically shifts the body centerline line by one Counteracts weight shift of the upper body. The burden on the knees is thereby significantly reduced. Moreover, the ski boot has the advantage that due to the flexibility of the shoe in the metatarsal area (i.e. Toe ball area) walking - compared to footwear with a stiff Sole - much easier, as a natural rolling motion of the foot possible. By the provided in the metatarsal area flexible Transition area, which allows a natural rolling motion while running, The ski boot is also for Tourengänger, Telemark skier, Snow Blader suitable.

Advantageously, the transition region in the upper part of the outer shoe by two in metatarsal region of the shoe opposite approximately V-shaped Recesses formed in the side walls to pivot the Front part about an axis transverse to the longitudinal extent of the shoe while running or while practicing the sport. Alternatively, the Transition region may be formed by a flexible material, which e.g. upset or is foldable. This has the advantage that the otherwise rigid Schoos back one Pivoting the shoe front part (= shoe cap) relative to relentless trained rear part of the shoe is not obstructed. It is advantageous both the shoe upper as well as the sole in the metatarsal area yielding or formed elastically deformable, so that a rolling movement as normal Shoes is possible. Alternatively, in the metatarsal area, an otherwise in known manner formed shoe upper part be provided a recess, which extends from the inside to the outside of the shoe upper.

Advantageously, the sole at least in the area where the ball of the foot to lie come up with an area of high flexibility. This area of high flexibility can be realized by the fact that in the field of foot pads a flexible Sole plate is inserted into a recess in the sole. Conveniently, The flexible sole plate is interchangeable, so that the flexibility depending on the sport is customizable if sole plates with different Elasticity coefficients are available. In principle, it is conceivable that the sole is made entirely of a flexible material, and that the flexible Transition area by appropriate training of a relatively stiff Material formed shoe upper part comes resp. is defined.

Advantageously, the sole, the side walls and the shaft of the outer shoe integrally. In this way, a substantially rigid connection ensured between the shaft and the metatarsal area of the sole. One such shoe can e.g. in a multi-part injection mold in one Work step to be established. Also conceivable is the side walls of the Shoe between the shaft and the metatarsal area of the sole in addition to reinforce, thereby exerting pressure on the Outer shoe shank (21) the side walls are not pressed apart.

In principle, it is conceivable that the inclination of the outer shoe with respect to The sidewalls, although changeable, but in a once taken Position is fixed, so sidewalls and the shaft a rigid Construct construction. This embodiment has the advantage that the inclination of the shaft is adaptable to individual needs, however, the functionality the shoe according to the invention is preserved. Advantageously, the shaft is in The area of the ankle hinged to the outer shoe, so that the outer shoe shaft (21) with respect to a pivot axis transverse to the longitudinal extent of the shoe is pivotable, and means are provided to the shaft in selected Determine pivoting. It is conceivable to run to the locking means solve, so that the upper shaft part is pivotable in a certain range, and that for practicing the sport, the pivotal position of the upper shaft part in a for Exercise of sports favorable position is established. The fixation of a once set shaft inclination can be adjusted by a screw Screw thread and nut connecting shaft and heel part, be realized.

Conveniently, the liner in the outer shoe is form-fitting taken and removed from the latter. However, it is also conceivable inextricably bonding the innerboot to the outerboot (e.g., by gluing or by means of a foam plastic), so that there is a one-piece shoe.

The outer shoe resp. the outer shell of the inventive shoe can in be known manner equipped with fixative to the foot and the Shin of the sports practitioner to fix. Usually the Fixation means buckles, ratchet buckles, etc., with which the shaft area and the Schuhrücken the outer shoe resp. the outer shell closed can be.

Another feature of the ski boot, concerns the fixation of the Compressible and flexible liner in the outer shoe. According to this Another aspect of the invention, the fixation of the Liner - in contrast to conventional footwear - essentially not by a contraction or a decrease in volume of the Outer shoe, but in that the shaft of the outer shoe as Half shell is designed such that the shaft portion of the compressible Liner the shaft of the outer shoe forward by a certain amount surmounted, and that for fixing the compressible liner at least two provided with locking means provided bands or belts, a so-called ankle band, which is layable around the instep and backwards and at an angle to the horizontal diagonally down over the ankle extends and the fixation of the heel in the heel part serves, as well as a shaft band, with which the shin / fibula of the shoe wearer to the outer shoe shaft can be fixed. This type of fixation of the liner on the outer shoe has the Advantage that the risk of the formation of pressure points while wearing far less than in shoes, where the volume of the outer relatively stiff Shell is reduced to fix the liner. Straps or straps have the particular advantage that they are free of pressure on the can lay compressible liner. Another advantage is that the Fixation of the liner already with a band with Velcro closure without great effort can be accomplished and therefore no consuming Buckles are needed. Another advantage is that the half shell with low Effort and therefore inexpensive to produce. By means of at least one Ristund a shaft band can be a surprisingly good grip of the foot and the Calf / tibia in the shoe can be achieved. Preferably, the Outer shank in cross-section C- or U-shaped and formed in substantially dimensionally stable.

As a locking means, the bands at the ends of a hook and loop fastener exhibit. However, it is conceivable that other known, releasable locking means too use, such as Timing belts and buckles. By using at least another variable length fixation band, which in the metatarsal Area around the foot resp. placed the foot-wearing liner and is tightened, the foot can also be fixed pressure free in the outer shell become.

The above described new way of fixation of a compressible or flexible Inner shoe in an outer shoe made of hard plastic (e.g. Polyurethane plastic) can be used advantageously in conjunction with a Outer shoe, in which the shoe front part of the outer shoe according to characterizing features of claim 1 is designed. Which is characterized resulting advantageous effects and other advantageous features already discussed above. It is expedient if the in cross section shell-shaped outer shoe shank is substantially dimensionally stable.

Advantageously, the liner has a sole insert with a footbed. A Sole insert with footbed significantly improves wearing comfort. It is appropriate, in the area of the heel bone balcony between the liner and provide the sole with a footrest. The footrest should in particular prevent the foot from tilting inwards.

According to a preferred embodiment, the footrest has a as Pad serving, substantially straight edge and one to the straight edge adjoining, preferably approximately semicircular support surface, wherein the Support surface is transverse to the straight edge concave and designed so that the Shoe insert about an axis parallel to the straight edge little yielding and transverse to the straight edge is more yielding. The footrest is preferably a Plastic part available from a thermoplastic material. One such leaves produced inexpensively by injection molding. Appropriately has the plastic part on the side opposite the concave side transverse to Straight edge extending, spaced ribs. The Ribs provide stiffening of the support in a first direction, but do not an elastic deformation of the support transversely to the first direction (= axis parallel to the ribs) with little effort too. This embodiment can be Good fit to the foot and ensures a good grip. Define advantageous the spaced-apart ribs spaces, in which preferably wedge-shaped spacer means can be inserted. With the wedges can the Footrest raised at selected positions towards the straight edge become.

The footrest described above can also be used in shoes other than Winter sports shoes are used. In particular, the footrest at Persons are used, who have a false statistic, which to various problem symptoms on the musculoskeletal system. Furthermore, the footrest can be used as a therapeutic agent.

By using a shoe with a bendable in the metatarsal area Transition area and a shoe upper, which forcefully with the metatarsal area, can be a completely new while skiing Driving techniques are used, which are explained in more detail below should: While in the previously known driving technique, the curvature of the ski exclusively by the forces acting on the ski while cornering state, can with the new, inventive shoe / ski system the Curvature of the ski in the binding area can be actively influenced when using the body weight a pressure is applied to the front. By the Pushing forward is by the largely rigid connection running from the shoe upper to the metatarsal area of the shoe sole the the latter bent downwards or, if the metatarsal area of the sole Via distance means with the ski surface in connection, the force directly in initiated the ski. It should be clear to the expert reader that by this novel shoe / ski system the driving technique, especially that of the Carvens or Snowbladens (in principle a short carving ski), once again is enriched significantly. It is therefore claimed a shoe / ski system, which differs from known systems in that Binding front part and binding back substantially in strength are decoupled from each other and a shoe with a metatarsal area flexible transition region is used, with rear shoe upper and shank together form a relentless connection, so that by means of the shoe upper a force on the metatarsal area of the sole exercisable. there is the shoe front part of the shoe by means of a flexible transition area provided in the metatarsal area vigorously decoupled from the back of the shoe largely to a Pivoting the front part in the foot ball area about an axis transverse to To allow longitudinal extension of the shoe when practicing the sport, and the Shank and the side walls to the transition area form a unyielding connection, so by means of the shoe upper one Force is exercisable on the metatarsal area of the sole. A powerful one Decoupling of the front and rear ski binding part can also be characterized be realized that the binding system, i. the front and the rear Binding part, are arranged on an elastically flexible binding plate.

Because the tie is usually a front shoe pad and a back shoe Heel pad has is between the front and the rear shoe pad advantageous a support for the middle sole region for introducing force into the Shi provided the shoe sole over the pad in direct contact with the ski surface is.

Conveniently, the position of the support in the shoe longitudinal direction adjustable. This has the advantage that the bending of the ski varies can be influenced. The sole pad is conveniently between Foot ball area and ankle area slidable.

Description of the embodiments

The sports shoe 11a shown in FIGS. 1 to 5 has an outer shoe 13 made of a tough elastic material, e.g. Polyurethane, and one in the outer shoe 13 recorded compressible resp. flexible liner 15. Essential Features of the outer shoe 13 on the one hand, that the sole 17 in the metatarsal region 19, i. where the balls of the foot are in the shoe, is flexible and on the other hand, that the rear part of the shoe 11a so is formed so that over the shaft 21 of the outer shoe 13, a force (arrow 37 in FIG Fig. 6) can be introduced into the metatarsal region 19 of the sole 17, i. through the Shank 21, the curvature of the sole 17 can be influenced when the shoe rest on the front and rear on distance means as e.g. in a ski binding, especially carving ski binding, the case is.

The upper part 23 of preferably made of a thermosetting plastic existing outer shoe 13 is according to the shown preferred Embodiment designed as a substantially open shell body, which essentially by the shaft 21, side walls 25a, 25b and Outer shoe front part 29 is formed. The Schäftrückwand designated 28 and the rear part of the side walls 25a, 25b together form the Outer Shoe Shaft 21. The upper part has one from the instep area to the shaft extending recess 30. In addition, in the metatarsal area 19 the upper part 23 in a side view V- or U-shaped recess 27 in the Side walls 25a, 25b provided. The recess 27 causes that Shoe front part 29 decoupled from the rear part of the shoe 13 forcefully is, so that the shoe front part 29 is pivotable about a transverse axis 32 (Fig. 1). It is conceivable, instead of a recess 27, the upper of the Outer shoe in this area compressible or foldable form, so that the Upper part 23, the bending of the sole 17 in the metatarsal area 19 not significantly impeded. It is also conceivable that the shoe upper in known Is formed, but one from the inside to the outside running has transverse recess.

In order to facilitate bending of the sole 17, the metatarsal area 19 be formed as a region of increased elasticity, which consists of a more elastic material than the rest of the sole. According to a preferred Embodiment, a recess 31 is provided in the sole 19, in which a flexible sole plate 33 can be inserted. The sole plate 33 may, depending on Use of the shoe a different coefficient of elasticity exhibit.

The other essential aspect of the novel shoe 11a is that the shaft 21 and the side walls 25a, 25b a substantially rigid resp. little yielding Construction form, so that one exercised by the shoe wearer forward Force (arrow 35 in Fig. 6) substantially directly on the metatarsal area 19th the sole 17 acts (arrow 37 in FIG. 6). When the shoe front part 29 and heel part 39 are clamped in a bond, not shown, results from the Nachvornedrrückt the shaft 21 a vertically downward acting Force component 41. This new functionality of the shoe 11a allows the Bending of the ski, also known as flex in technical jargon, is actively involved in skiing influence, as explained below.

As already mentioned, the inner shoe 15 is received in the outer shoe 13. Of the Liner 15 may be modeled on known inner shoes, which above slotted (slot 43). In the front part of the inner shoe, a tongue 45 be arranged. The liner 15 corresponds in its external dimensions, as far as the inner and outer shoe overlap, largely the Inner dimensions of the outer shoe 13. The inner shoe shaft 47 protrudes from the Shaft 21 of the outer shoe 13 upwards advantageously a certain extent, about the risk of bruises through the upper outer shoe edge margin excluded. The tongue 45 is for getting into the inner shoe 15 from the Slit 43 can be pulled out to provide a larger access opening put.

The proposed open design of the outer shoe allows the Inner liner 15 largely to fix with ribbons in the outer shoe 13, wherein These bands are claimed in the exercise of the sport to train. It has It has been shown that the fixation of the foot by means of ligaments produces a high Comfort is achievable.

For fixation of the compressible inner boot are advantageously at least two with Provided locking means provided bands 51,53. A so-called ankle band 51, which is layable around the instep and from the instep to the back and in one Angle to the horizontal extends obliquely downwards, serves to fix the heel in the heel part. The ankle strap 51 is at the Schenktrückwand 28 in the amount of Ankle or below fixed on the outer shoe still undisturbed above. Becomes the ankle strap 51 stretched, so the heel of the shoe wearer can no longer lift off the sole. With a shaft band 53, which at the top around the Outer shoe shaft 21 and the forward of the outer shoe shaft forward outstanding part of the inner shoe shaft 47 is laid, is the tibia / fibula the shoe wearer can be fixed to the outer shoe shaft.

A Ristband 55, which in the metatarsal area on the outer shoe, preferably attached to both sides of the upper sole, the fixation of the foot of the Shoe wearer on the sole 17.

To determine the drawstrings 51,53,55 is preferably a Velcro closure. Shaft band 53 and ankle band 51 have for this purpose at one end each advantageously a metal tab 57, through which the other end of the respective Bandes can be geschelt. The drawn by the metal tabs 57 ends the bands 51 resp. 53, which externally, e.g. can be ticked on the adjacent to the shoe part of each band, which with Schlaufen is occupied, covered and determined. Slime and Checkmarks form in a known manner a Velcro closure.

Although the instep strap 55 may be formed analogous to the straps 51, 53, FIG this advantageous with the upper of the inner shoe releasably connectable. This Conveniently also done with the help of a Velcro closure, wherein the upper with slits and the band ends 59a, 59b of the Ristbandes 55th inside are checked with check mark. The band ends can be trained like that 59a, 59b in any way according to the need of the shoe wearer to the Liner can be placed. Advantageously, the ends 59a, 59b of the Ristbandes 55 placed around the liner so that it is on the inner back cross (Fig. 1.3).

The shoe 11b of Figures 3 and 4 differs from that of Figure 1 in that on the outer shoe shaft a calf support 61 integrally formed thereon Tongues 63a, 63b is provided. The tongues 63a, 63b serve as a support for the Shaft band 53, which through a slot 54 rear of the calf support is looped (Fig. 5). The tongues 63a, 63b extend from the shaft rear wall 28 forward beyond the front outer edge of the boot.

The essential functional aspects of the inventive shoe 11 are in Fig. 6 explained in more detail. Assuming that the shoe is in front and back in a not shown in FIG. 6 conventional ski binding is clamped and a force 35 in the shoe longitudinal direction is exerted forward on the shaft 21 is, then results in a vertically acting on the sole 17 force component 41st The result of this is that the sole 17 is in the flexible metatarsal area sags.

The embodiment according to FIG. 7 differs from that of FIG 3 in that the shaft 21a in the region of the ankle on the upper part 23rd is hinged, so that the shaft 21 a about an axis 65 transverse to the longitudinal direction of Shoe is pivotable. Adjustable locking means 67 on the back of the shaft 21a ensure that the once set angle of inclination of the shaft is fixed, so that a force in the front part of the sole can be introduced through the shaft.

The adjustable locking means 67 may e.g. in a known manner by a Screw 68 may be formed with nut 69, which upper part 23 and shaft Fix 21a in the adjusted pivot position.

The shoe according to FIG. 8 differs from the other shoes in that that as a means of fixing the inner shoe belt instead of bands are provided. In this embodiment, a preferably two-part Ankle strap 101 is provided, which is layable around the instep and from the front extends obliquely downwards at an angle over the ankle. The Ends of the belt 101 are laterally through a recess 103 in the side wall guided and connected inside with the shoe. The belt 101 has teeth 105, which can interact with a buckle 107. The buckle 107 is preferably designed as a ratchet buckle to the belt 101 with little To be able to attract effort. To avoid bruises is on the An underlay 109 for the belt 101 is provided.

A sheep belt 111 is formed analogously to the ankle strap 101. Of the Shear belt 111 is also known as a specialist toothed belt formed, which by means of a buckle 107 can be tensioned.

For a good grip, it is expedient if the liner an anatomical Footbed has (Fig. 9 and 10). The footbed can be replaced by a corresponding Sole insert 71 can be realized, which can be inserted into the inner shoe. To one Tilting the foot inward to a large extent in the area can of the heel bone balcony (arrow 72 in FIG. 9) additionally has a footrest 73 (FIGS. 9 and 10) can be arranged. The footrest 73 is in the flattened state approximately semicircular, in cross-section concave plastic part, which on One side is smooth (smooth surface 75) and on the other side across Straight edge 77 of the plastic part 73 extending ribs 79 has. Is the Footrest 73 inserted into the liner 15, so the smooth surface 75 is in Area of the heel bone balcony (Sustemtaculum tali) on the inside of the Sole insert 71 and increases it by a certain amount (Figures 9 and 10). As In particular from Fig. 11a-c can be seen, the plastic part 73 is concave, wherein the transverse ribs 79 are designed to leak towards the ends are (see Fig. 10b). The ribs 79 ensure that the footrest 73 around a Axis 81 parallel to the straight edge 77 relatively rigid (FIG. 11 a), but transversely thereto, i.e. parallel to the ribs 79, with little effort elastically deformable. The footrest 73 therefore has the advantageous property that this in Foot length well adapted to the inner foot. The individual adaptation of the Foot rest 73 to the foot can be made by wedges 83, which in interspaces 85 can be inserted between the ribs 79.

In Figures 12 to 14, the novel interaction between the Schischuh 11 and a ski 89 illustrated. The ski boot 11 is in one Binding, which a binding front part 91 for cooperation with the Front part of the sole 17 and a binding back 93 for cooperation with the heel part of the sole 17 has.

Binding front and back 91, 93 may have a known security bond however, the front part 91 and the binding back 93 are separate parts. Between the binding front part and the binding back 93 is a Sole support 95, which is arranged in the metatarsal region 19 of the sole 17. Now, when the shaft 21 is pressed forward, a force acts on the Sole pad 95 directly on the ski 89 a, wherein the curvature reinforced becomes. Depending on the driving style or application, the sole pad 95 can be arranged in different positions.

In Fig. 13 it is shown that the ski 89 under load over its entire Length can bend evenly. The fact that newly via shoe a vertically acting force is exercisable on the ski and this over the entire Length is flexible, has a particularly advantageous when cornering. By the even curvature of the ski when cornering must be less strong be tilted and the speed remains high even in the curve.

According to another embodiment, the metatarsal region 19 of the Sole 17 with the apex 97 of an arcuate damping element 99th together. The damping element 97 is, for example, an elongated Spring element whose ends are connected to the Schioberfläche such that the Dämpfüngselement protrudes in an arc from the Schioberfläche. presses the ski boot on the spring element 97, so is a curvature of the ski counteracted.

It thus turns out that with the inventive shoe / ski combination different effects can be achieved.

It should also be apparent to those skilled in the art upon reading the present specification have become that different variations of the shown Embodiments are possible without departing from the spirit departing. In particular, it is conceivable, the compressible liner so make that this as a so-called "soft boot" without outer shoe as Footmuff is usable. So it would be possible, the outer shoe only for Exercising the sport. Next is also conceivable, the outer shoe as Shoe with a rear entry form, the shaft then backwards would be essentially open. The heel part would then be designed so that the Heel can not slip backward at a pressure to the front. In terms of the shoe insole serving as a foot rest is to mention that this is not must necessarily be semicircular, but that other outlines conceivable are. Of importance is only that the footrest fits well to the inner foot in the area of the heel bone balcony.

The present invention relates to a winter sports shoe 11 and a Wintersportschuh- / Schikombination. The winter sports shoe stands out appropriate training / design of the metatarsal area 19 of the shoe the shoe front part forcefully from the rear part of the outer shoe (13) is largely decoupled, i. compliant, so pivoting or unwinding of the front part 29 in the foot ball area about an axis 32 transverse to Longitudinal extension of the shoe 11 when practicing the sport or while running is possible. In addition, the outer shoe shaft 21 and the side walls 25a, 25b formed to the transition region 27 substantially unyielding, so that by means of the outer shoe 21 a force on the metatarsal area 19 of the sole 17 is exercisable. The shaft of the outer shoe resp. the outer shell goes well beyond the ankle area, as in alpine boots well known and common, so that a corresponding leverage on the metatarsal area can be exercised.
