Definitions

  • the invention relates to an insert for a shoe, in particular for a sports shoe, which extends at least in the forefoot area, preferably in the entire foot area, of the sole.
  • the invention also relates to a sole provided with such an insert and to a shoe having such a sole.
  • the wearer of such a shoe with a very thin and stiff sole could stand well and safely on level ground, i.e. such a shoe would give the wearer good stability on level ground, however, the wearer of such a shoe could walk poorly and unsafe with this shoe, and furthermore he would not have good stability on uneven ground because the rigid sole of such a shoe would do not adapt to an uneven floor and make it impossible for the sole of the shoe to roll while walking on the floor.
  • the sole of the shoe In order to enable the wearer of the shoe to walk well and safely by a good rolling movement of the sole of the shoe on the floor, the sole of the shoe must be soft and flexible.
  • British patent specification GB-A-1 257 524 discloses a spiked stiffening insert made of metal or plastic material which is embedded in the sole of the shoe and is intended in particular for golf shoes.
  • the task underlying this stiffening insert is to solve the problems of holding the spikes and isolating the foot from the pressure of the spikes when using lighter, softer and more flexible cellular sole materials.
  • an uncontrolled bending of the shoe, in particular an uncontrolled torsional bending of the middle part can be avoided in order to avoid a reduction in the comfort of the foot and an early deformation of the upper shoe.
  • the generally flat insert extends over the entire length of the shoe sole and all spikes of the forefoot area are attached to it, the attachment points of the spikes forming slight indentations on the insert.
  • This stiffening insert therefore not only achieves the desired transverse reinforcement in the forefoot area of the shoe sole, but at the same time the forefoot area is also stiffened in the longitudinal direction of the sole, which undesirably complicates the rolling movement of the shoe sole when running.
  • a stiffening insert made of metal is known from US Pat. No. 4,439,937, which extends from the central part of the forefoot area of the shoe sole backwards to the rear end of the heel area and has the function of a support in the joint or instep area to build.
  • the front part of the forefoot area of the shoe sole is expressly released from the stiffening insert so that it remains vertically flexible, as is necessary for a good rolling movement, but this has the disadvantageous consequence that there is little lateral stability here.
  • the stiffening insert which in the embodiment of interest extends over practically the entire length of the shoe sole, is designed and inserted into the shoe sole in such a way that the toe area for supporting a toe steel cap and the joint area for supporting the ankle each directly under the insole In contrast, the remaining part of the forefoot area and the heel area of this insert are deepened so that they can be covered continuously by a layer of soft elastic sole material, in order to improve foot comfort in the ball and heel area compared to the use of a stiffening insert that can be used directly anywhere stretches under the insole.
  • These recessed areas of the stiffening insert are formed in that the material of the insert at the transition from the respective raised to the respective recessed area is bent in a step-like manner along bending lines which run transversely to the longitudinal axis of the sole.
  • these bending lines do not significantly change the stiffness of the insert, so that the insert stiffens the sole in practically the same extent in the transverse and in the longitudinal direction, and thereby the rolling movement of the shoe sole is hindered to the extent that the transverse stiffness is increased.
  • the object of the invention is, in particular, to provide an insert for the production of shoes in which the risk of the foot bending sideways and thus the risk of ligament tears and strains is as low as possible and which at the same time has an excellent running movement of the Allow shoe sole with optimal stability.
  • the invention is intended to provide a shoe sole and a shoe, in particular a sports shoe, with these properties.
  • This object is achieved according to the invention with an insert which extends at least in the forefoot area, preferably in the entire area of the sole, in that the insert is rigid at least in the forefoot area in the transverse direction of the sole, in particular in the respective rolling area of the sole, but vertically in the longitudinal direction of the sole is flexible.

  • the insert according to the invention is very particularly preferably designed to be elastically resilient, as a result of which the sole of the shoe always returns to its original position on its own.
  • the insert according to the invention in its particularly preferred embodiment, is designed to be pressure-resistant perpendicular to the sole plane, which is very important because it causes selective pressures from the floor to be distributed over the entire surface of the insert, so that pressures from small stones, uneven floors o.
