Definitions

  • the present invention relates to a footbed for footwear, in particular for a high heel shoe, comprising a sole-shaped body, such as a flat insert, with a forefoot, a metatarsal and a rear foot, and arranged with at least one arranged on a flat top th raised to support a foot.
  • heel shoes Shoes with a heel area that is much higher than a forefoot, so-called heel shoes, have been very popular for many years, especially for ladies.
  • heel shoes may be defined by the hindfoot area being at least 2 cm higher than the forefoot area.
  • the weight of a person or the pressure on the human foot pressure is mostly distributed evenly on the forefoot, midfoot and hindfoot area
  • heel shoes the main load focuses primarily on the forefoot area due to the increased heel position.
  • extremely high and thin heel shoes especially the front part of the foot, that is the ball of the foot, is loaded. This uneven distribution of pressure on the foot often leads to high heel shoes when worn, especially in comparison to flat shoes uncomfortable and uncomfortable.
  • US 2004/0211086 A1 discloses, for example, an insole for a heel shoe in which the pressure distribution on a tread surface of a foot is adjusted by means of a sickle-shaped elevation for supporting a heel and a circular elevation arranged in the metatarsal area for supporting a metatarsus can be at least partially displaced from the forefoot area in the direction of the middle and hindfoot area.
  • the footbed according to the invention has a base body which has in the midfoot area a first elevation in the area of an inner foot side (medial) and a second elevation in the area of an outer foot side (lateral).
  • the elevations each preferably have a convex upper side and each form a pressure-increased zone, whereby both a mechanical support of individual foot areas and a stimulation of individual nerve cells and muscles of the foot serving for positioning and rolling movement can be effected.
  • the thickness of the ridges is dependent on the relative base thickness of the sole thickness, however, the ridges may be positioned on an insole of a shoe even without a connecting through sole base.
  • the pressure acting on the foot not only in its longitudinal extent but also transversely to the longitudinal extension can be distributed in an advantageous manner targeted to almost the entire foot contact surface, especially in the forefoot and hindfoot area.
  • the elevations are preferably offset in the longitudinal extent of the base body to each other.
  • the first elevation may be arranged in an area of the base body such that its highest point is located below the projection of the medial heel bone (sustentaculum tali) when resting one foot, and the second elevation in a region of the base body in which it rests Foot the distal end of the fifth metatarsal bone (metatarsalia) is arranged.
  • the second increase thereby preferably acts as a lateral abutment to the first increase.
  • an active surface pair can be formed which has a width over the entire width and length of the foot, in particular in the forefoot and hindfoot region.
  • shared pressure load and improved, especially those of a flat shoe resembling, rolling movement of the foot while walking allows.
  • a rolling curve can be achieved, which runs clearly s-shaped, in particular from the first elevation arranged on the inner foot side to the outside on the outside foot side second elevation and then back to the arranged on the inside foot area, in which the metatarsophalangeal joint is applied.
  • an occurrence on only the medial forefoot, also called “heel” can be avoided and an improved gait can be achieved.
  • the first elevation extends from the midfoot region to the hindfoot region.
  • the first increase in the longitudinal extent of the base body is in each case identical, in particular half and / or symmetrically, in the midfoot region and the rearfoot region.
  • the first increase in their longitudinal extent may differ significantly from the longitudinal arch supports known to the person skilled in the art, whose longitudinal center of gravity and / or in their longitudinal extension generally leads much further forward.
  • the pressure load in the heel region can be transferred from the middle of the heel region into an edge region, so that the pressure distribution, in particular transversely to the longitudinal extension of the main body, can be distributed to almost the entire contact surface even in the heel region.
  • a gripping of the heel in the longitudinal extension of the main body behind the increase can be avoided, so that the increase is perceived as relatively comfortable.
  • the first elevation is formed exclusively in a half of the main body directed toward the rear foot region in the longitudinal extension of the main body, and the second elevation is formed exclusively in a half of the main body directed longitudinally to the forefoot region.
  • the first elevation is sickle-shaped and extends along an inner leg side edge in the longitudinal extent of the base body, a highest point of the elevation preferably being arranged in the region of the inner leg side edge, in particular below the sustentaculum tali of a foot located on the footbed.
  • the first increase in the direction of mecanical philicity is continuously increasing
  • the corners of the sickle shape preferably lie on the mecanical axis of the body.
  • the pressure distribution in the rear foot region can be increased and the pressure sensation at the elevation can be improved.
  • the first elevation preferably has a longitudinal tilt formed in the longitudinal extension of the base body and a transverse tilt formed transversely to the longitudinal extent of the base body.
  • the upper-side contour of the base body can be tilted at least in sections by a first angle and by a second angle from the horizontal, wherein the first angle leg is rotated about an axis of rotation at a positive angle between 20 and 35 degrees, which may be arranged substantially parallel to the longitudinal axis of the base body, and the second angle leg is rotated at a positive angle between 2 and 22 degrees about a second axis of rotation, which is arranged substantially parallel to a transverse axis of the base body.
  • the pressure distribution can be increased and the pressure sensation at the elevation can be improved.
  • a pressure load or a pressure which would act without the increase on the forefoot can be absorbed in the side area of the hindfoot area.
  • the first elevation is formed such that the area of the first elevation projected on a horizontal plane is 5% to 25% of that on the horizontal plane projected area of the entire body forms.
  • the second elevation is substantially rectangular, round, semicircular, trapezoidal or elliptical, and increasingly formed in the direction of an outside foot side edge.
  • the second increase to a mecanicfußitride
  • the fourth and fifth metatarsal bones of a foot arranged in this area can be slightly raised, so that a pressure which would act exclusively on a partial area of the forefoot area, in particular the inner foot area, would at least partially coexist with the outer edge area of the foot can be absorbed, and thereby the overall pressure distribution can be improved.
  • a pressure which would act exclusively on a partial area of the forefoot area, in particular the inner foot area would at least partially coexist with the outer edge area of the foot can be absorbed, and thereby the overall pressure distribution can be improved.
  • such pressure absorption in the front outer foot area acts as compensation for the pressure absorbed by the first elevation in the rear inner foot area and thereby essentially centers the centerline axis of the body weight in comparison to a shoe without such a second elevation.
  • first and second elevation not only achieves a more uniform pressure distribution in the direction of the longitudinal and transverse axis, but also a more stable and more fluid rolling action of the foot, which substantially relieves the foot and knee joints which are normally heavily overloaded in heel shoes brings with it.

  • the third increase is formed tear-shaped or triangular in particular in the longitudinal direction.
  • the third elevation is arranged in the region of the basic body in which the second and third metatarsal bones are arranged in the case of a foot located on the basic body. This can be effected both a mechanical support of individual foot areas as well as a stimulation of individual to the position of the foot and thus for pressure distribution in the shoe serving nerve cells.

This causes a similar feeling on the foot as with a flat shoe.
  • At least one forefoot elevation is additionally arranged in the forefoot area.
  • a pressure force acting in particular in the direction of the forefoot can be absorbed by the foot in the proximal toe area.

  • the fifth elevation 7, also called convexity, serves as a toe joint stabilizer and is nothing more than an elevation projecting on the underside 25 of the main body 2.
  • the base body 2 in the region of the bulge 7 with a flat upper side 24 has an increased material thickness D for forming a pressure-reduced zone.
  • the pressure load concentrated on a partial region of the forefoot region 21 can be partially displaced to the entire width of the forefoot region 21 as well as the rear foot region 23 by the big toe joint shock absorber 7 and the general soft and continuous footbed 1.
  • the big toe midsole damper 7 and the toe gripper 6 are directly attached to the compensation of the slight lifting of the inside of the foot 27 (supination), which together increase the unrolling of the foot 100 via the great toe joint and "turning it forward". of the foot 100, which has a positive effect on the gait and is compensated by the two elements 7 and 6.
  • FIGS. 3 a and 3 b show a comparison of the pressure load on the foot 100 when walking a lady with the same heel shoes on the one hand with a conventional footbed S and for comparison on the other hand with the footbed 1 according to the invention.
  • the comparative representations thus show that Result of a practical investigation.
  • the pressure load is represented in each case by dark circles, in particular in the forefoot region 21 by the reference numeral 101 and in the rear foot region 23 by the reference numeral 102.
  • the footbed S shown on the left half of the illustration in FIG. 3a and the footbed S shown in the right half of the illustration illustrate the pressure load on the footbed S or on the underside of a foot 100 when the conventional footbed S is used
  • the weight or pressure force acting on the footbed S is concentrated in each case on a small part of the forefoot area 21.
  • the pressure load in the forefoot area 21 is highest in the area of the first four toes.
  • the pressure load in the region of the fifth toe that is to say on the outside foot side 26 of the forefoot region 21, and in the rear foot region 23 of the conventional footbed S is in each case relatively small.
  • the pressure applied to the foot 100 concentrates predominantly on the forefoot area, in particular on the medial forefoot and especially on the distal area of the first and second metatarsal bone.
  • the footbed 1 according to the invention shown in Figure 3a on the right half of the illustration and in Figure 3b on the left half of the illustration shows the pressure load when using the same high heel shoe with the footbed 1 according to the invention.
  • the force acting on the footbed 1 pressure force respectively both on the entire area of the forefoot area 21, in particular on an inner foot side edge 27a to an outer foot side edge 26a, as well as on almost the entire area of the rear foot area 23 distributed. Consequently, the pressure applied to the foot 100 is distributed over the entire length and width B of the footbed 1 except for the metatarsal area 22, which is almost unloaded.
  • the main body 2 and the elevations 3, 4, 5, 6, 7 are constructed as a unit of a homogeneous substance mixture.
  • the production of the footbed is particularly cost-effective.
  • the main body 2 and the elevations 3, 4, 5, 6, 7 be produced by means of a so-called SD printing method known per se.
  • the surface contours of the basic body 2 can be adapted individually to a human foot 100.
  • the footbed can be made individually according to the recorded data of the foot.
  • a viscose-elastic material or-preferably in the production of printing-a polypropylene is preferably used as the production material for the main body 2.
