Definitions

  • the present invention relates to a high-heel shoe with a shock-absorbing, noiseless heel, which can also be made extremely high and, above all, slim. These require by the reinforcement of the load and pressure conditions a special type of damping.
  • a shock-absorbing, noiseless heel which can also be made extremely high and, above all, slim. These require by the reinforcement of the load and pressure conditions a special type of damping.
  • the invention allows a painless wearing of high heels over a longer period.
  • the joints which are particularly affected by the extreme inclination, compared to conventional shoes with high heels, spared.
  • This is made possible by a biodynamic construction in the heel, which picks up and imitates the function of the physiological shock absorption and thereby provides stability with simultaneous, minimal relative movement to cushion the shocks.
  • the sole of the foot has an anatomical structure that is adapted to the local pressure loads like a shock absorber.
  • the sole of the foot deforms non-linearly when loaded. As the load increases, it initially offers little resistance to the compressive force, but becomes heavier under heavy load ( Biomechanics of the Foot, Debrunner, Hilaire, 1998, p.19 ). If the vault and the muscular and joint structures of the foot are intact, the entire body burden is distributed on these resilient sole surfaces, another load distribution almost always leads to discomfort ( Orthopedics, Orthopedic Surgery: Patient-Oriented Diagnosis and Therapy of the Musculoskeletal System, Debrunner, 2002, p. 1123 ).
  • the physiological damping behavior of the heel when placed on the ground is based on the principle of displacement.
  • the heel bone lowers when loaded on the floor and shifts the underneath soft tissue structure to the periphery. It results - under load on a level ground - under the heel a hemispherical pressure distribution with maximum pressure under the heel bone.
  • a pressure of about 30 Newton / cm 2 is given.
  • the weight will be distributed over a much smaller area and may result in a compressive load which may be a multiple of the normal load.
  • the process of absorption of the body load begins with the initial ground contact.
  • the ankle When walking in flat shoes, the ankle is in neutral position (inner angle 90 degrees) during initial ground contact. This allows the heel to serve as a support for a long enough period of time to create an optimal rolling motion over the heel to maintain movement continuity.
  • the ankle In high shoes, the ankle is in a different starting position: the angle is not 90 ° due to the inclination of the entire foot, but may, depending on the height of the heel between 100 ° and in extreme cases up to 160 °. At an average height of 10 cm, the foot is at an angle of approximately 135-140 °. This has a significant impact on the weight distribution and the load forces acting on the joints. Already in the normal gait in flat shoes, it can come to a vertical force when putting on the heel, which exceeds the one's own body weight. The higher the heel, the larger this angle and the greater the pressure on the heel on initial ground contact.
  • This pathological movement structure is additionally reinforced by high and elegant shoes, which have a heel diameter of only a few millimeters at the lower end.
  • the entire weight is centered in this area. The larger this area is due to a larger heel diameter, the better it can spread.
  • the smaller the diameter of the heel at the lower end or the heel spot, the more weight strikes a very small area (pressure force / area [Newton / cm 2 ]). This increased pressure can no longer be compensated in the long term by the normal, physiological damping.
  • the joints are overstressed because of the unphysiological foot position and due to the increased pressure. Such changes can be expected from a heel strike of 5 to 6 cm ( Hansen, Childress, Journal of Rehab R & D, Volume 41 (4), pages 547-554 ).
  • Some flat shoes especially sports shoes, are already offered with various damping systems. These are intended to reduce the stress on the joints, especially the foot and knee joints, at the onset of the heel and facilitate rolling over the midfoot and bale.
  • damping systems are usually integrated in flat shoes in the shoe sole and are often arranged at least in the heel area.
  • the DE 42 19 152 A1 describes a heel with an elastic outer cover which inverts around a hard and firm inner core. The construction does not allow sufficient cushioning or a slim design of the heel.
  • the DE 2 908 023 A1 discloses a heel with an intermediate layer of elastic material. Considering that at least the body weight acts on the heel when placing the foot (depending on gait and speed - eg when running - the force can be 1.5 to 2.5 times that), it can be assumed that a relatively thick layer of elastic material will be required, which precludes the stability and practicality of such shoes.
  • the DE 298 07 242 U1 describes a footbed for women's shoes with a heel strike of 30 mm, which is the lateral cavity between foot and shoe fills and before the heel has an arcuate recess. This is intended to surround the heel and prevent slippage of the foot towards the toe.
  • the GB 974,254 discloses a shock absorbing heel construction having a shoulder that has a lower portion that terminates in a lower surface and a relatively thick, expanded portion that terminates in an upper surface.
  • the shoulder has a bore extending between the upper and lower surfaces and through the flared portion. In the expanded portion an enlarged recess is provided in which a block of an elastically compressible material is firmly attached.
  • the ES 2278 474 describes a shock-absorbing shoe heel consisting of a heel formed by a top and a bottom. The upper part and the lower part are connected by a connecting piece which has a spring.
  • the US 2,807,100 discloses a resilient heel construction with a reciprocating spring-loaded piston provided in a piston housing aligned with the longitudinal axis of the heel.
