Definitions

  • the invention relates to the field of shoe technology, in particular for sports and leisure shoes, and relates to a sole for a running shoe.
  • running shoes In many sporting activities, such as running, the shoe's first contact with the ground occurs in the heel area. As a result, the forces acting on the shoe in this area are significantly greater than in the forefoot or metatarsal area of the sole. To take this into account, running shoes generally have particularly pronounced cushioning in the heel area. Such a construction makes it possible to ensure at least sufficient vertical cushioning, but the pronounced cushioning has a negative effect on the overall weight of the shoe. The result of this is that the running shoes known in the prior art either have an unsatisfactory cushioning effect and/or are heavy.
  • known soles for running shoes often lack a variable damping effect across different areas and sub-areas of the sole.
  • a sole with an improved cushioning effect is provided, which preferably has a low weight.
  • hierarchical damping is provided from the heel area through the metatarsal area to the forefoot area, with the damping effect preferably not being segmented.
  • a sole with a cushioning effect is provided which has improved durability over a longer period of time.
  • a sole is provided with variable cushioning across different areas and sub-areas of the shoe.
  • the sole according to the invention for a running shoe comprises a soft, elastic midsole with an underside that comes into at least partial contact with the ground.
  • the midsole has several channels running in the transverse direction. These channels are arranged in a lateral region of the midsole in at least a first and a second horizontal plane.
  • the first and second horizontal planes are vertically offset from one another.
  • the channels are delimited in the longitudinal direction by a front wall and a rear wall.
  • the channels can also be deformed vertically and/or in the longitudinal direction until they are closed under the effect of vertically and/or longitudinally acting forces that occur during running.
  • first and second horizontal planes are vertically offset from one another, a so-called hierarchical damping can be formed.
  • the cushioning is no longer limited to individual segments of cushioning elements, but essentially extends over the entire midsole.
  • the hierarchical damping is particularly advantageous because the channels in the first horizontal plane, which is formed closer to the underside, are more flexible and can therefore be deformed more easily than the channels in the second horizontal plane. This makes it possible to develop an additional damping effect at specific, intended places, whereby both the overall damping effect and the wearing comfort of the wearer can be significantly improved. This effect can be further enhanced by additional channels in additional horizontal levels.
  • a horizontal plane of the sole describes a plane which is aligned substantially parallel to the underside of the sole, or substantially parallel to the ground. It is also understood that the horizontal plane can also be slightly curved. This can be the case, for example, if the sole is bent vertically slightly upwards in the forefoot area and/or in the heel area, as is typical for running shoes.
  • the longitudinal direction L of the sole is described by an axis from the heel area to the forefoot area and thus extends along the longitudinal axis of the sole.
  • the transverse direction Q of the sole runs transversely to the longitudinal axis and essentially parallel to the underside of the sole, or essentially parallel to the ground.
  • the transverse direction thus runs along a transverse axis of the midsole.
  • the vertical direction V denotes a direction from the underside of the sole towards the insole, or in the operative state towards the wearer's foot, and thus runs along a vertical axis of the midsole.
  • the lateral area of the midsole refers to an area along the lateral inside and outside sides of the midsole of the running shoe of a pair of running shoes, wherein the area extends in the direction of the longitudinal axis of the midsole.
  • the horizontal extent of the lateral area is a few centimeters, for example 0.1 to 5 cm, preferably 0.5 to 3 cm.
  • the medial area of the midsole refers to an area along the longitudinal axis in the middle of the midsole, which extends in the transverse direction of the midsole.
  • the horizontal extent of the medial area is a few centimeters, for example 0.1 to 5 cm, preferably 0.5 to 3 cm.
  • a channel is to be understood as meaning a recess, which can typically be tubular.
  • a channel is completely or partially bordered by channel walls.
  • the channels are empty.
  • the channels it is also possible for the channels to be filled in some embodiments, for example with an elastically deformable foam or with a gas.
  • the channels are each delimited by a front and a rear wall.
  • a wall can be formed by a flat surface, or by two or more surfaces which have one or more folded edges.
  • the term “folding edge” also includes embodiments that are slightly rounded and therefore not completely angular. Such a folded edge therefore runs along the channel and thus in the transverse direction of the midsole.
  • the front and/or the rear wall of a channel can be designed as a so-called stable wall.
  • a stable wall refers to a wall that has no folding edge and extends essentially in the vertical direction of the midsole. A wall with a folded edge is therefore easier to deform than a solid wall.
  • the deformability of the channels may include, for example, the vertical merging of the channel walls and/or the shearing of the channel in the longitudinal direction.
  • the phrase “underside that comes into contact with the ground when running” also includes embodiments in which the midsole is coated with a further layer, for example an outsole. In such cases, contact with the ground is at least partially established by means of such an outsole.
  • the soft, elastic midsole is formed in one piece.
  • the soft-elastic midsole therefore preferably consists of a single material and is therefore more stable than a midsole consisting of several components, in particular components that are glued or welded together.
  • the channels have lateral openings in the lateral region of the midsole.
  • the channels can be deformed vertically and/or horizontally in the longitudinal direction under the action of vertically and/or longitudinally acting forces that occur during running until the side openings are closed.
  • the upper and lower canal walls can touch each other under the forces of running.
  • the channels may have an elongated shape in cross-section in the longitudinal direction.
  • the channels in the lateral area of the midsole are completely delimited by the soft, elastic midsole.
  • the channel walls can therefore be formed entirely by the midsole in the lateral region of the midsole.
  • the channels in the side view of the sole can therefore be described as transverse openings in an otherwise preferably one-piece midsole.
  • the midsole has no segmentation. This can significantly improve the durability of the sole, as the midsole is in In general, it is significantly more stable compared to a segmented midsole. Furthermore, fatigue of the soft-elastic midsole is avoided or at least significantly reduced over the lifespan of the sole or running shoe. This allows the advantageous cushioning effect of the midsole to be maintained consistently over a long period of time.
  • the channels in a medial region of the midsole are delimited on one side by a layer extending over the heel region, the metatarsal region and the forefoot region.
  • the at least one side is the side facing the wearer's foot in the operative state.
  • the channels can therefore have a substantially U- or V-shaped cross section in the medial region of the midsole.
  • the cross section can also be described by a trapezoid that is open at the top.
  • the layer extending over the heel area, the metatarsal area and the forefoot area consists of an elastic and incompressible plate.
  • the midsole has a groove extending in the longitudinal direction from the heel area to at least the metatarsal area.
  • the groove only extends into the metatarsal area.
  • the channel extends essentially through the entire midsole and is only connected at the tip of the sole and the heel end.
  • the channel is open to the ground and is limited on the side flanks by the soft-elastic midsole and on the base surface either by the insole of the running shoe or by a layer described above.
  • the channel is particularly preferably essentially V-shaped, so that the flanks are inclined. This prevents stones and pieces of wood from becoming trapped.
  • the channels in the transverse direction in the midsole can preferably be open towards the gutter.
  • An embodiment has proven to be particularly advantageous in which the groove extends from the heel to the metatarsal area.
  • the channel enables the channels to be better deformed, which is particularly advantageous for thicker walls, such as those preferably provided in the heel and metatarsal areas.
  • thicker walls such as those preferably provided in the heel and metatarsal areas.
  • a significantly weaker damping effect is typically required, which is why the canal walls in this area are significantly thinner and are therefore more easily deformable than the canals in the heel and metatarsal areas.
  • At least one channel has a slope in the vertical direction.
  • the vertical gradient of the channels runs in the transverse direction and can increase in particular from the lateral area towards the medial area.
  • a channel that has such a slope can typically be arranged in the lateral region of the midsole in the first horizontal plane and, due to the slope in the medial region, can be arranged in a further third horizontal plane that is vertically offset from the first horizontal plane.
  • a channel can be arranged in the lateral region of the midsole in the second horizontal plane and, due to the slope in the medial region, can be arranged in a further fourth horizontal plane which is vertically offset from the second horizontal plane.
  • first and second horizontal planes are arranged vertically offset from one another
  • third and fourth horizontal planes are identical, i.e. are not vertically offset from one another.
  • third and fourth horizontal planes it is also possible for the third and fourth horizontal planes to also be arranged vertically offset from one another.
  • all channels in the heel and metatarsal area have a vertical slope.
  • Such a vertical gradient of the channels in the heel and metatarsal area has the advantage that the stability in these areas is increased and any swimming effect that may occur is reduced or avoided.
  • the vertical gradient of the channels runs in the transverse direction and can increase in particular from the lateral area towards the medial area.
  • the midsole preferably has a groove extending in the longitudinal direction from the heel area into the metatarsal area.
  • all channels in the heel and metatarsal area can have a vertical slope.
  • the channels can be open in the transverse direction of the midsole towards the gutter.
  • the vertical gradient can be an upward gradient, i.e. the channel rises in the operative state towards the foot of the wearer.
  • the channels in the lateral region of the midsole can be arranged in a first, lower horizontal plane and a second, upper horizontal plane and can be arranged in a third or fourth horizontal plane due to the slope in the medial region, the third or fourth horizontal plane is arranged in the vertical direction above the first and second horizontal planes.
  • the channel is completely formed by the midsole in the lateral region of the midsole and only partially formed by the midsole in the medial region, so that in the medial region at least one side of the channel, typically the upper side, i.e. facing the wearer's foot in the operative state Side, is limited by a layer extending over the heel area, the metatarsal area and the forefoot area.
  • the vertical slope can be arranged between the lateral and medial region or can also be arranged partly in the medial and partly in the lateral region of the midsole.
  • a midsole according to the invention with one or more channels which have a vertical gradient has several advantages. Firstly, this enables efficient cushioning in the lateral area of the midsole. At the same time, however, the stability of the Sole increased so that the so-called swimming effect associated with horizontal deformation is prevented or at least reduced. Another advantage is the generally increased stability of the medial area of the midsole, resulting in an improved and more stable running feeling. In embodiments with a gutter described above, any instabilities associated with the gutter are prevented by one or more vertically rising channels.
  • a width of the soft-elastic midsole between at least one channel and the underside is thinner in the lateral region of the midsole than in the medial region of the midsole. This makes the medial area of the midsole more stable. Furthermore, the service life of the running shoe or the sole can be significantly increased because fatigue of the soft-elastic midsole is avoided or at least significantly reduced over the service life.
  • width of the soft-elastic midsole between each channel in the heel and metatarsal area and the underside is thinner in the lateral area of the midsole than in the medial area of the midsole.
  • the channels of the first horizontal plane are arranged horizontally offset in the longitudinal direction from the channels of the second horizontal plane.
  • the channels can be arranged in such a way that when the heel strikes, a channel is first deformed in the first horizontal plane. This channel would therefore be the first channel in the transverse direction when viewed from the heel area in the running direction.
  • the subsequent second channel can then be offset vertically upwards in the second horizontal plane and arranged horizontally towards the tip of the sole.
  • the following third channel in the transverse direction would accordingly again be arranged in the first horizontal plane and offset horizontally from the second channel in the direction of the sole tip.
  • Such an alternating arrangement can extend over the entire length of the sole, or preferably only over the heel and metatarsal area.
  • the horizontal offset of the channels in the first and second horizontal planes has several advantages. Thanks to the hierarchical arrangement, the cushioning is no longer limited to individual segments of cushioning elements, but essentially extends over the entire midsole.
  • the channels in the second horizontal plane which are generally arranged above, ie in the operative state in the direction of the wearer's foot, the first horizontal plane, can only be deformed with greater force due to their positioning than the channels in the first horizontal plane below.
  • the channels of the second horizontal plane are therefore suitable for increasing the damping effect in particularly stressed areas, such as the heel and metatarsal areas. By horizontally offsetting the channels, the overall width and therefore the weight of the midsole can be minimized without this having a negative impact on the cushioning effect.
  • the channels in the forefoot area are only arranged in a single horizontal plane.
  • the additional cushioning effect due to the arrangement of channels in the transverse direction in a second horizontal plane, which is arranged above the first horizontal plane is only required in heavily stressed areas of the sole, such as the heel area and metatarsal area, so that channels in the second horizontal plane in the forefoot area can be dispensed with.
  • the channels have a hexagonal and/or pentagonal cross section in cross section, particularly preferably in the lateral region of the soft elastic midsole.
  • at least one corner of the penta- or hexagon is arranged in the longitudinal direction, ie in or against the running direction.
  • a corner of the penta or hexagon can be arranged in the running direction towards the tip of the sole or against the running direction towards the end of the sole.
  • the penta- or hexagon have an asymmetry, for example the sides of the penta- or hexagon in the running direction, ie sides which run essentially parallel to the ground, can be designed to be longer than the remaining sides of the penta- or hexagon. This gives the channels an elongated shape in cross section.
  • the channels have two sides in cross section that are essentially parallel to one another and to the bottom or to the underside.
  • the angular shape of the channels in the cross section has positive effects on the deformability of the channels.
  • the hexagonal shape is preferably suitable for channels that are arranged in the second, upper horizontal plane, since their position means they have less deformability. This deformability can be increased to a certain extent by the hexagonal shape. Consequently, due to the correct shape of the channels, the deformability of each individual channel can be individually and flexibly adapted to its position and the specific forces acting on the channel.
  • the channels typically have a height (extent of the channels in the vertical direction) of 2 to 10 mm and a length (extent of the channels in the longitudinal direction) of 5 to 35 mm, preferably 10 to 30 mm, in the lateral region of the midsole.
  • the front wall of at least one channel in the first horizontal plane has a folded edge in the heel area.
  • the rear wall of the at least one channel in the first horizontal plane in the heel area is designed as a stable wall.
  • the rear wall therefore has no folding edge and preferably consists of an edgeless surface.
  • Such an embodiment has proven to be particularly advantageous, since the strongest forces act on the rear wall of the at least one channel in the heel area due to the initial contact of the shoe when stepping in the heel area.
  • the rear wall designed in this way means that these relatively strong forces can be absorbed efficiently.
  • the folded edge on the front wall of the at least one channel in the heel area a deformability of the channel until it closes under the forces that occur when running.
  • the cross section of the respective at least one channel in this embodiment can be pentagonal, with one corner of the pentagon directed towards the tip of the sole in the running direction and one side of the pentagon being arranged in the rear wall.
  • the rear wall of at least one channel in the first horizontal plane in the heel area can have a folded edge and the front wall of the at least one channel in the first horizontal plane in the heel area to be designed as a stable wall. This can be useful, for example, for providing an alternative damping profile if required.

  • the rear wall of the at least one channel has a folded edge in the first horizontal plane in the forefoot area.
  • the front wall therefore has no folding edge and preferably consists of an edgeless surface.
  • the greatest forces that act on the forefoot area come from the runner's footprint. It has therefore proven to be particularly advantageous that the front wall of the at least one channel in this area is designed as a stable wall and does not have a folding edge. This ensures that the push-off force emanating from the runner can be used practically completely for the push-off and is not absorbed by the sole. Since at the same time the rear wall of the at least one channel in the forefoot area has a folded edge, an excellent damping effect when stepping and rolling is still guaranteed in this area.
  • the front wall of at least one channel in the first horizontal plane in the forefoot area can have a folded edge and the rear wall of the at least one channel in the first horizontal plane in the forefoot area to be designed as a stable wall. This can be useful, for example, for providing an alternative damping profile if required.
  • the front wall and the rear wall of at least one channel each have a folded edge in the first horizontal plane in the midfoot area.
  • relatively small forces occur, since a large part of the forces are absorbed in the heel area when you step and a large part of the impression acts on the forefoot area of the sole.

  • hexagonal channels can be provided in cross section for this purpose, which have an elongated shape in the longitudinal direction.
