Definitions

  • the invention relates to a shoe bottom for a sports shoe and a shoe, in particular a sports shoe for running.
  • the ground reaction force refers to the reaction force of the ground to the force that the body transfers to the ground through the shod or unshod feet when stepping.
  • the so-called force application point (KAP) marks the origin of the force in the running direction (x direction according to a right-handed three-dimensional coordinate system with x, y and z axes), in the vertical direction (z direction) and in the lateral or medial direction ( y direction) acting force components resulting vector of the ground reaction force.
  • the ground reaction force i.e. its anterior-posterior force component (x-direction) and its vertical force component (z-direction) acts on the ankle joint initially (after foot strike) behind the joint axis of rotation.
  • the KAP is therefore located behind (posterior) the ankle joint axis of rotation
  • the upward direction of force creates an external torque, which initiates plantar flexion of the foot in the ankle joint.
  • the external torque at the ankle changes its sign and direction. This causes the ankle joint to undergo accelerated dorsiflexion.
  • This externally generated Dorsiflexion moment is balanced by the plantarflexion muscles, in particular the triceps surae muscle, the dorsiflexion is thereby slowed down and ultimately the ankle undergoes plantarflexion for push-off from the ground.
  • the ground reaction force acts in the sagittal plane behind the knee joint and creates an external flexion moment.
  • This external flexion moment is provided by the knee extension muscles, i.e. the Mm. vasti, and the rectus femoris muscle, counteract an internal extension moment.
  • the flexion of the knee joint is slowed down in the early support phase and the knee joint is stretched for push-off.
  • the ground reaction force is generated, i.e. i.e., their medio-lateral (ml or y-direction) directed force component and their force component pointing in the z-direction) at the ankle joint in the early support phase an external eversion moment, which tilts the hindfoot inwards and the ankle joint with the distal Tibia pushes medially.
  • the heel bone (calcaneus) is rotated inwards around the vertical axis and adducted.
  • internal rotation is imparted to the talus and, as a result, the tibia.
  • EPM transverse plane in the knee joint
  • Medialization of the distal tibia results in increased adduction of the knee joint.
  • the KAP In the push-off phase or in the second part of the stance phase when running, the KAP is initially found laterally and only finally medially under the forefoot.
  • the KAP is lateral to the ankle (and knee) joint and produces a force against the force of the inversion muscles (tibialis anterior muscle, tibialis posterior muscle, flexor hallucis muscle).
  • the external adduction moment (EAM) and the torque (ERM) in the transverse plane (ERM) at the knee joint are therefore further increased.
  • the task relating to the shoe bottom is achieved by a shoe bottom with the features specified in claim 1.
  • the shoe according to the invention has the features specified in claim 12.
  • the support sole is essentially comparable to the classic insole of a shoe bottom and, according to the invention, can be made, for example, from a viscoelastic foam (e.g. from an ethylene-vinyl acetate polymer (EVA) or copolymer (EVAC), in particular with a density of approximately 55 Asker ShoreC), a fiber composite material (e.g. carbon) or the like.
  • a viscoelastic foam e.g. from an ethylene-vinyl acetate polymer (EVA) or copolymer (EVAC), in particular with a density of approximately 55 Asker ShoreC
  • EVA ethylene-vinyl acetate polymer
  • EVAC copolymer
  • the support sole is in any case flexibly deformable.
  • the support sole of the shoe bottom is therefore supported in the area of its edge section on the rear foot part and on the forefoot part in the direction of the vertical axis of the support sole and outwards in a direction radial to the vertical axis.
  • the support sole is therefore in both loaded and unloaded operating states, i.e. H. at any time, arranged in sections between the support device.
  • a force application point of the ground reaction force that is located eccentrically with respect to the longitudinal center axis of the support sole can be centered in the direction of the longitudinal center axis of the support sole at any time during the stance phase.
  • the point of application of the ground reaction force can be directly in the center of the U-shaped rear foot part of the support device and thus under, regardless of the attachment point or the attachment direction the heel bone of the foot is pushed and thus centered under the heel bone and the still neutral ankle joint.
  • the associated eccentric compression of the rear foot part due to the inventive mounting of the support plate on the elastically deformable rear foot part of the support device leads to a corrective force directed in the direction towards the longitudinal central axis on that support plate section on which the KAP attacks.
  • the force application point is found in the operational use of the shoe bottom below the knee joint.
  • the posterior part, ie the U-shaped rear foot part, of the support device enables AP control of the force application point. While running on the bottom of the shoe, external initial plantar flexion moments at the ankle joint can be counteracted. By centering the force application point, the cause of the external eversion and adduction moments at the ankle joint will be minimized or eliminated.
  • the force application point can be controlled like a funnel when the shoe bottom comes into further contact with the ground and can be guided centrally anteriorly and directed to the forefoot part of the midsole.
  • the forefoot part of the elastically deformable support device enables the force application point to be taken over from the rear foot section of the shoe bottom and to be guided further anteriorly centrally under the foot.
  • the forefoot part is preferably opened anteriorly.
  • the forefoot part can be U-shaped in a manner corresponding to the rear foot part and can encompass the forefoot section of the support sole (including its front free end section or tip).
  • the U-shaped forefoot part of the support device is then in the area of the apex, i.e. H.
  • the material is advantageously made with weakened material.
  • the U-shaped forefoot part of the support device in said area can in particular have a reduced overall height compared to the rest of the forefoot part (measured in the direction of the vertical axis of the shoe bottom).
  • the shoe base according to the invention does not only symptomatically counteract overpronation or eversion or knee adduction. Rather, the causes of these symptoms when running and thus the increased stress on the musculoskeletal system when running compared to the (everyday) stress can be reliably counteracted.
  • the sole base according to the invention is also suitable for other shoes, in particular sports shoes.
  • the support sole can have a receptacle or pocket for the support device, into which the support device engages.
  • the support sole preferably has a contact or support surface for the support device in the area of the pocket that is curved corresponding to the support surface (i.e. shaped complementary to the support surface, and therefore concave).
  • a push-off island with an outsole covering is arranged between the two legs of the forefoot part of the support device.
  • the push-off island can, for example, consist of foamed soft rubber, preferably with a low density of approx. 40 Asker ShoreC.
  • the surface of the outsole covering of the push-off island is set back, ie lowered, relative to the surface of the outsole covering of the two legs of the forefoot part of the support device, preferably in the direction of the vertical axis (z-direction) of the shoe bottom.
  • the height difference mentioned is between 2 and 4 millimeters, in particular 3 millimeters.
  • the push-off island is preferably segmented by flex zones in order to ensure the necessary flexibility of the shoe bottom during its use.
  • the course of the flex zones can be adapted to an externally rotated foot attachment that is often found in runners.
  • the leg of the rear foot part arranged medially on the support sole and the leg of the forefoot part arranged medially can (in particular only) merge into one another in the area of the coupling section (metatarsal bridge of the support sole).
  • the two aforementioned legs can be made in one piece with one another in this area.
  • the cross section of the forefoot part of the support device is preferably smaller overall than the cross section of the rear foot part (RFT) of the support device.
  • the height of the forefoot part decreases in the direction of the central axis of the shoe bottom towards the tip of the shoe bottom.
  • the rear foot part and the forefoot part of the support device preferably comprise an elastomer or are formed from such an elastomer. This allows a desired damping capacity of the shoe bottom to be set in a simple and cost-effective manner.
  • the rearfoot part and the forefoot part can each consist of or include solid material or a foamed elastomer.
  • the rear foot part (RFT) and/or the forefoot part (VFT) of the support device can/can, for example be made of a (highly responsible) thermoplastic elastomer, such as thermoplastic polyurethane (TPU) with a low density (45-50 Asker ShoreC).
  • the support device can also consist of an elastically deformable fiber composite material.
  • the rear foot part and the forefoot part of the support device are each designed to be tubular. This allows a particularly high mechanical damping capacity of the support device to be achieved.
  • the support device i.e. the rear foot part and the forefoot part, has a round, i.e. essentially circular or ellipsoidal, cross-sectional shape overall or over a large part of its (longitudinal) extent.
  • the resulting (functionally) quasi-point support under the strand- or tubular support device enables the undesirable joint-side leverage of the ground reaction forces explained at the beginning to be minimized as early as the first contact of the shoe bottom ("impact") with the ground.
  • the support device is preferably glued to the support sole.
  • the support device can also be arranged welded to the support sole or held in a press fit on the support sole.
  • the support device can have at least two sections that differ from one another in their material properties.
  • the two medial legs of the rear foot part and the forefoot part can consist of a less elastic material than the remaining areas of the support device.
  • a desired support capacity of the support device can be adapted to the (individual) needs in some areas.
  • the outsole covering of the shoe bottom can in particular be profiled and preferably consists of an advantageously abrasion-resistant rubber or another suitable material.
  • the outsole coating creates the necessary friction between the bottom of the shoe and the respective surface guaranteed and counteracts undesirable slipping, especially when placing the foot and pushing off.
  • the shoe according to the invention has a sole bottom and, in a manner known per se, an upper shoe part attached to the sole bottom.
  • the shoe can in particular be designed as a running shoe. It goes without saying that the shoe can also be designed for sports other than running, in particular for tennis, sqash, or as a so-called leisure shoe.
  • Fig. 1 shows a schematic series image of a runner 10 during a natural running movement at different times from the beginning of the ground contact of a foot 12 until after the take-off phase of the foot 12 in question, with the ground reaction force f shown in each case in a side view.
  • Fig. 2 shows the foot 16 provided with a shoe 14 , the ankle joint 18 , the lower leg 20 and the knee joint 22 of the runner 10 ( Fig. 1 ) with ground contact in the early stance phase at successive times A, B, C with ground reaction force f displayed in the frontal plane.
  • the ground reaction force f (more precisely its medio-lateral (ml-/y-) component and z-component according to a right-handed three-dimensional coordinate system) causes an external eversion moment at the ankle joint 18 in the early support phase, which tilts the rear foot inwards (B, C) and the ankle joint 16 pushes medially with the distal tibia of the lower leg 18.
  • the medialization of the distal tibia results in increased adduction of the knee joint 20 and an increase in the leverage of the ground reaction forces f in the frontal plane to the knee joint.
  • Leverage forces on the ankle and knee joints 18, 22 derived from the ground reaction forces f can lead to overloading and damage to the ankle joint 18 and the knee joint 20 and require unnecessary muscle work.
  • Fig. 3 are force application points (KAP) 23 of the ground reaction forces f introduced into a conventional shoe bottom 24 of a shoe shown in two-dimensional spatial resolution in their respective position on the shoe bottom 24 during a ground contraction phase.
  • the force application points 22 show clear medial/lateral deviations from the longitudinal central axis 26 of the shoe bottom 24 from posterior to anterior, which essentially coincides with the axial projection of the longitudinal axis of the foot.
