Definitions

  • the present invention lies in the field of shoe technology and relates to a midsole for a sport shoe, such as running shoes or particularly gymnastic or cross-fit shoes, a shoe sole with such a midsole and a shoe with such a midsole or shoe sole shoes.
  • Soles for sport shoes typically comprise different cushioning systems.
  • Relevant cushioning systems known in the prior art relate to channels which enable cushioning, spring elements, such a vertically extending dampers, or fluid filled chambers, e.g. chambers which are filled with a gel or with air.
  • the majority of such cushioning systems focus on the forces which occur during long or medium distance running in which vertical acting forces predominate.
  • when running downhill also forces acting horizontally, i.e. along a longitudinal direction of the shoe sole occur.
  • a shoe being known in the prior art is for example disclosed in EP 3 449 751 A1 , WO 2017/158408 A1 , US 2019/150563 A1 , EP 2 848 146 A1 and US 2021/227926 A1 .
  • the sportsperson does not only perform unidirectional movements as it is the case for long or medium distance running, but also other movements, such as side steps, jumps, lunges, squats and the like, which are not unidirectional, but also entail laterally or medially acting forces on the wearer's foot.
  • cushioning typically requires a certain degree of flexibility
  • many cushioning systems known in the prior art evoke instabilities, in particular in the medial and lateral directions. While this is not a significant issue for unidirectional running, it is a profound disadvantage for other activities as mentioned above, in particular as such instabilities may cause severe foot injuries.
  • cushioning requires a certain flexibility, it typically leads to a less efficient force transmission.
  • a sportsperson jumps not all of the body force is used for the push-off, as a certain part will be absorbed by the cushioning system. Therefore, it would be desirable not only to provide efficient cushioning, but also to allow for an efficient force transmission into the desired movement.
  • a shoe comprising a midsole is provided which allows for a greater flexibility of the shoe for side step movements, splits and the like.
  • significant instabilities in particular lateral or medial sided instabilities are avoided.
  • a midsole is provided which allows for a greater wearing comfort, in particular during side step movements.
  • the invention relates to a shoe, in particular a gymnastic or cross-fit shoe, which comprises a midsole.
  • the shoe further comprises an upper being attached to the midsole.
  • the upper is preferably a textile upper, such a knitted upper or a non-woven upper.
  • Such an upper comprises a foot arch, i.e. the part of the upper which in the worn state extends over the foot arch of the wearer.
  • the midsole comprises a forefoot area, a heel area and midfoot area.
  • the midfoot area is generally arranged between the forefoot area and the heel area.
  • the midsole further comprises a top layer and an opposing, i.e. oppositely arranged, base layer.
  • the top layer and the base layer typically delimit the midsole in the vertical direction.
  • the midsole comprises a heel edge and a midsole tip.
  • a longitudinal direction of the midsole extends from the heel edge to the midsole tip. It is understood that in the operative state, i.e. in the worn state, the toes of the wearer are arranged at the midsole tip, respectively towards the midsole tip, and the heel of the wearer is arranged the heel edge, respectively towards the heel edge.
  • the midsole further comprises one or more horizontal tilting slits.
  • the one or more horizontal tilting slits are each arranged on a medial side of the midsole or on the lateral side of the midsole. It is understood however that there may be one or more horizontal tilting slits on the medial side and also one or more horizontal tilting slits on the lateral side of the midsole.
  • Each of the horizontal tilting slits divides the midsole in a corresponding midsole top portion and a midsole base portion.
  • the midsole top portion is in the vertical direction arranged above the horizontal tilting slit and the midsole base portion is in the vertical direction arranged below the horizontal tilting slit.
  • Each horizontal tilting slit is configured to tilt the corresponding midsole top portion, i.e. the midsole top portion above this horizontal tilting slit, with respect to the corresponding midsole base portion, i.e. the midsole base portion being arranged below this horizontal tilting slit.
  • the corresponding horizontal tilting slit widens, i.e. a slit angle defined between the midsole top portion and the midsole base portion widens. This entails a higher flexibility of the midsole, in particular during side step movements or splits.
  • the slit is a horizontal slit, there is no profound instability of the midsole, e.g. in the medial and/or lateral direction.
  • the shoe further comprises a support mechanism which is connected to the midsole top portion or to several or all of the midsole top portions, which are arranged in the vertical direction above the one or more horizontal tilting slits of the midsole. Furthermore, the support mechanism extends over the foot arch of the upper.
  • the support mechanism is configured to support tilting of the midsole top portion with respect to the midsole base portion.
  • the support mechanism is configured such that laterally or medially forces acting on the upper are at least partially transmitted to the midsole top portion, respectively the multiple midsole top portions.
  • a force acting towards the medial side may induce a pulling effect on the midsole top portion on the lateral side. Thereby, tilting is facilitated.
  • the longitudinal direction LO of the midsole is described by an axis from the heel area, respectively from the heel edge, to the forefoot region, respectively to the midsole tip, and thus extends along the longitudinal axis of the midsole.
  • the transverse direction TR of the midsole respectively the shoe sole extends transversely to the longitudinal axis and substantially parallel to the base layer of the midsole, or substantially parallel to the ground in the operative state.
  • the transverse direction runs along a transverse axis of the midsole.
  • the transverse direction extends from the medial side of the midsole to the lateral side of the midsole, respectively the shoe sole.
  • the term “extending along/in the transverse direction” may typically refer to extending towards the lateral side of the midsole and the term “extending against the transverse direction” typically refers to extending towards the medial side of the midsole.
  • the vertical direction V denotes a direction from the base layer to the top layer of the midsole in the direction of the insole, or in the operative state in the direction of the foot of the wearer, and thus runs along a vertical axis of the midsole respectively the shoe sole.
  • the term “extending along/in the vertical direction” typically refers to extending towards the top layer of the midsole and the term “extending against the vertical direction” typically refers to extending towards the base layer of the midsole.
  • the terms “above” or “below” typically refer to an element being arranged in the vertical direction above or below another element.
  • the longitudinal direction, the vertical direction and the transverse direction may all be perpendicular to each other.
  • the lateral side of the midsole is the outer perimeter of the midsole between the heel edge and the sole tip, which in the worn state rests against the outer instep of the wearer's foot.
  • the indication “horizontal” refers to a direction or plane extending in the longitudinal and the transverse direction and being perpendicular to the vertical direction.
  • a horizontal tilting slit is thus parallel to the base layer, the top layer or also to the ground.
  • the medial side of the midsole refers to the inner perimeter of the midsole between the heel edge and the sole tip, which is located opposite the lateral side.
  • the midsole may typically along the longitudinal direction be divided into a forefoot area, a heel area and a midfoot area being arranged between the forefoot area and the heel area.
  • the forefoot area extends from the midsole tip against, i.e. opposite, the longitudinal direction to 30-45% of the total length of the midsole in the longitudinal direction.

  • the one or more horizontal tilting slits are arranged in the midfoot area of the midsole and optionally in the forefoot area.
  • one or more horizontal tilting slits are arranged only in the midfoot area of the midsole.
  • Such an arrangement has the advantage that a midsole is provided which is flexible for sideway movements, but whose heel area does not comprise such a horizontal tilting slit, which increases the stability of the midsole. This is advantageous, as in particular during running initial contact with the ground is conducted with the heel area and thus having horizontal tilting slits only in the midfoot and optionally the forefoot area increases the stability.
  • the distance between each of these horizontal tilting slits and the heel edge is between 20% and 40%, in particular between 25% and 35% of the total length of the midsole.

  • protrusion 201 is inserted into recessed pocket 117 which is arranged in the lateral portion of midsole 10 and protrusion 204 is inserted into recessed pocket 120 which is arranged in the medial portion of midsole 10.
  • the protrusions form a bulge forming a convexity towards midsole 10, respectively in general towards base layer 102 of midsole 10.
  • Shoe sole 1 also comprises insole 40, which is in the vertical direction V arranged on elastic plate 20.
  • elastic plate 20 is arranged between midsole 10 and insole 40.
  • Fig. 4 shows an embodiment of elastic plate 20 as it may be used in a shoe sole 1 according to any of the embodiments described herein.
  • Elastic plate 20 comprises protrusions 201, 202, 203 and 204.
  • a least the protrusions being inserted into recessed pockets of midsole 10 have a shape which corresponds to the shape of the recessed pocket.
  • the corresponding protrusion generally fits into the recessed pocket in which it is inserted and may contact the midsole defining the recessed pockets.
  • the protrusions form a bulge which forms a convexity.
  • Fig. 5 shows a side view on the lateral side of elastic plate 20 shown in Fig. 4 .
  • elastic plate 20 does not only comprise protrusions 201, 202, 203 and 204 which are inserted into recessed pockets, but also protrusions 205 and 206, which are inserted into central notch 121 of midsole 10 (cf. Fig. 7 and 8 ).
  • protrusions 205 and 206 being inserted into central notch 121 are in the longitudinal direction LO arranged one after the other, i.e. behind each other.
  • Fig. 6 shows a front view of elastic plate 20 in which it can be seen that protrusions 201 and 204, which are inserted into recessed pockets of midsole 10, sandwich protrusion 205 which is inserted into central notch 121, i.e. protrusion 205 is in the transverse direction arranged between protrusion 201 and 204. Furthermore, the protrusions are in the transverse direction spaced apart from each other. All of these protrusions each form a bulge forming a convexity.
  • Shoe sole 1 comprises midsole 10 which may for example be a midsole as shown in Fig. 2 . It can be seen that protrusions 205 and 206, which are inserted into central notch 121 of midsole 10 (see for example Fig. 2 ), penetrate through central notch 121. However, in this and optionally also in any other embodiment as described herein, the protrusion(s) being inserted into central notch 121 and penetrating through central notch 121 are aligned with base layer 102, i.e. they do not protrude from midsole 10, thereby generating an even contact surface for contacting the ground. Furthermore, as the central notch penetrates midsole 10, protrusions 205 and 206 are visible from the bottom side, i.e. when viewed onto base layer 102. Furthermore, horizontal tilting slit 105 is shown, which divides midsole 10 into a midsole top portion 106 and midsole base portion 107 which are arranged on top of each other.
  • Fig. 8 shows a front view of shoe sole 1 shown in Fig. 7 . Also in this figure it can be seen that protrusions 205 and 206 extend through the central notch and are aligned with base layer 102. Furthermore, protrusions 205 and 206 and also base layer 102 are covered by portions of outsole 4.
  • the horizontal tilting slit is configured such that the midsole top portion is tiltable with respect to midsole base portion about a tilting axis extending in the longitudinal direction LO, i.e. and axis extending towards the viewer.
  • midsole base portion 107 remains essentially fully in contact with the ground.
  • Horizontal tilting slit 105 has a depth D, which extends against the transverse direction from the lateral side towards the medial side of midsole 10, but does not fully penetrate midsole 10.
  • midsole top portion 106' may even contact midsole bottom portion 107' which are arranged above and below medial sided horizontal titling slit 105'.
