Definitions

• the invention relates to a shoe which has: a) an upper part for receiving a foot, b) an outsole with a sole bottom which is essentially convexly curved in the longitudinal direction, c) a midsole arranged between the upper part and the outsole.
• Shoes are known from public prior use. Also known for example from EP 1 124 462 PI are so-called MBT (Masai Barefoot Technology) shoes, which have a convexly rounded shape in the running direction with an inserted heel softside. This soft shoe bottom construction is designed to reduce the foot's grip when walking and to strengthen the muscles because the body must be actively balanced.
• MBT Mosai Barefoot Technology
• the invention is based on the object to provide a shoe of the type mentioned, which allows a simple, effective and cost-effective way destabilizing walking in the sense of Masai Barefoot technology.
• this invention solves the problem in that the outsole and midsole in the longitudinal direction
• a shoe is any footwear suitable for walking.
• the term includes closed and open shoes such as sandals.
• the top is the foot enclosing area of the shoe. It can be made of leather, plastic, a fabric or other suitable materials.
• the outsole is in contact with the ground. It is convexly curved in the longitudinal direction, so that a rolling go is made possible. The curvature may extend continuously over the entire length of the outsole or have discontinuities. Between top and outsole, a midsole is arranged. For example, this midsole may be configured to form the footbed. Above the midsole, for example, an insole, an insert or the like may be arranged.
• the outsole and midsole span an area with each other through the weight of the user of compressible voids. These cavities cause the corresponding area to be deformed by the weight of the walking user, thus forming the area deformable during walking and thus destabilizing the foot. To include between them means that the cavities are located above the bottom of the outsole and below the top of the midsole. You can either in the material of the outsole, the midsole or extend into both areas.
• the essence of the invention is not to form the destabilizing portion of the shoe by a separate material which is arranged as a soft insert in the sole, but in a simple manner by a partially hollow design of the material of the outsole and / or midsole.
• the area is located in the back two thirds of the shoe, preferably in the area of the back half of the shoe. Its compressibility thus destabilizes especially the heel area of the foot.
• the compressible cavities are an extension in the direction of uprising (the contact direction is the normal or perpendicular to the footprint of the shoes) of the
• Shoe which initially increases in the area of compressible cavities in the longitudinal direction from front to back, passes through a maximum and then decreases again.
• this region of compressible cavities can thus have, for example, approximately a cushion shape.
• the area of compressible cavities preferably has an extension of 20 to 50%, more preferably up to 40%, more preferably 25 to 35% of the total length of the shoe.
• this region of compressible cavities can have an extent of 60 to 100%, preferably 75 to 100%, more preferably 90 to 100% of the total width of the shoe. 100% means that the area extends essentially over the entire shoe width, whereby of course the fact must be taken into account that the side area of the outsole or midsole is preferably closed, ie the cavities are not open to the side or to the outside are.
• the volume of a cavity is preferably between 0.1 and 10 cm 3 , more preferably 0.2 and 8 cm 3 , more preferably 0.2 and 5 cm 3 .
• the volumes of the cavities may have, for example, between 0.4 and 0.8 cm 3 in volume.
• the volume may for example be between 2 and 8 cm 3 , preferably between 3 and 7 cm 3 , more preferably between 4 and 6 cm 3 , in particular about 5 cm 3 .
• the region of compressible cavities has a plurality of webs projecting in the footprint direction of the shoe, which form the walls of the cavities and thus enclose cavities between them.
• the webs may preferably extend substantially in the longitudinal and / or transverse direction of the shoe.
• the distance between the webs can according to the invention be 0.5 to 2.5 cm, preferably 1 to 2 cm.
• the height of the webs in the region of greatest height may be between 0.5 and 2.5 cm, preferably 1 and 2 cm.
• the thickness of the webs (in the sole plane) may preferably be between 2 and 6 mm, more preferably 2 and 4 mm.
• the webs may be integrally connected according to the invention with the outsole. This means that the webs are part of the material of the outsole. Alternatively, it is possible that the webs are part of the midsole and thus are integrally connected thereto.
• the compressibility of the area of compressible cavities is also due to the choice of the material of these webs (which are usually part of the running or midsole) adjustable. For example. For example, this material may have a Shore A hardness of 40 to 80, preferably 50 to 70.
• the outsole and / or the midsole may be made of a polymeric material. It can be firm or foamed
• a suitable polymeric material may be, for example, ethylene vinyl acetate (EVA), available under the name Phylon.
• EVA ethylene vinyl acetate
• the shoe additionally has a further region of compressible cavities in the front region. In this way, not only the heel area of the foot is destabilized but also the front area of the sole of the foot.
• FIG. 1 shows a longitudinal section through a shoe according to the invention
• FIG. 3 is a view of the outsole with a dimensioning
• Fig. 4 is a plan view of the outsole with dimensioning
• Fig. 5 shows schematically the structure of the outsole and midsole of a second embodiment of the invention.
• the shoe according to the invention has an upper part 1 on a sole construction explained in more detail below.
• An outsole 2 forms the footprint of the shoe on the ground.
• the tread of the outsole 2 has a substantially convex curvature in the longitudinal direction. It can be seen that this curvature does not run completely continuously, but that at 3 the outsole has a discontinuous course of the curvature and a substantially flat region.
• a midsole 6 is arranged above the outsole 2 above the outsole 2.
• the midsole 6 is contoured in the area facing the outsole 2 in such a way that it accommodates the area of compressible cavities and substantially closes with the upper edge of the webs 4.
• an insole 7 and optionally an insert 8 are arranged above the midsole 6 .
• the cavities 5 are compressible in the course of the load of the shoe by the user. This means that the webs deform 4 under pressure from above and thereby reduces the size of the cavities 5.
• the individual components of the shoe are connected to each other, for example glued.
• the outsole 2 may in the embodiment of a suitable material such as rubber with a Shore A hardness of 61 and the midsole 6 of a polymer such as ethyl vinyl acetate (trade name Phylon) with a Shore A hardness of 55 consist.
• FIGS. 3 and 4 show different dimensions of an outsole and of the area of compressible cavities arranged therein. These dimensions are for an embodiment with the shoe size 43. All dimensions are given in mm.
• the volume of a cavity in the middle is approximately 5.7 cm 3 (17 ⁇ 19 ⁇ 17.5 mm).
• the thickness of the webs 4 in this embodiment is about 3 mm.
• Figure 5 shows schematically outsole 2 and midsole 6 of a second embodiment of the invention. It corresponds to the first embodiment, but the outsole 2 has a second region of compressible cavities 9 in the front region.
• the midsole 6 is contoured in the region facing the outsole 2 in such a way that it receives the corresponding region 5 or 9 of compressible cavities both in the front and in the rear region and substantially closes off with the upper edge of the webs 4.
