Definitions

  • the present invention concerns the structure of a sole for footwear wherein the sole is built up by a number of layers of different, equal or mainly equal or similar materials, wherein the sole comprises a heel section running from the rear end of the footwear and forwards to about the middle of the footwear sole, and a middle section comprising a supportive and less resilient material, wherein this middle section runs from abut the end of the heel section and forwards along the sole to about three quarters of the length of the sole estimated from the edge of the heel, where there internally in the heel section is located a pliable material, and wherein in a middle layer of said heel section of the sole there is located a bracer under the pliable material so that the heel section is depressed when loading the pliable material for through this depression to bring the middle section of the sole to, relative to the heel section, become elevated by the load thus providing support to the metatarsal of the foot by the depression of the heel section as well as thereby distribute the load both with respect to the sole per se and with respect to the weight distribution over the foot, across
  • Correct and shock-absorbing footwear is essential for avoiding many and often serious problems and diseases associated with tissue, tendon and muscle wear in the feet, knees, hips and back, incorrect posture, walking and running comfort.
  • diseases and injures are e.g. sciatica, Achilles and mechanical injury or irritation, muscular tensions, chronic headaches, chronic hip and knee pains, etc.
  • the form of the feet is different from individual to individual. It is therefore important that footwear is adjustable to the form of the foot of each person in every detail from a normal foot curvature to persons being flat-footed. Also the external shape should be adjusted to the purpose of the footwear. Footwear being used for holidays (e.g. high-heeled shoes, plateau shoes) as well as shoes being used for work (protective shoes, rubber boots, supporting shoes (hairdressers, nurses, paramedics) etc.) and/or leisure time (leisure shoes, running shoes, jogging shoes, football shoes, etc.) should all be able to provide as good support to the foot as possible.
  • holidays e.g. high-heeled shoes, plateau shoes
  • shoes being used for work protective shoes, rubber boots, supporting shoes (hairdressers, nurses, paramedics) etc.
  • leisure time leisure shoes, running shoes, jogging shoes, football shoes, etc.
  • shock absorbers in the front section and/or heel section in running shoes and athletic shoes (football, handball, basket, etc.).
  • Static loads of the foot e.g. standing work
  • the tendons in the metatarsal/foot arch may without any correction/support give cramps in the foot, a depressed foot arch (flatfoot) as well as load injuries in the calf and lower spine.
  • load injuries may also be distributed to the neck and may also give a headache/migraine.
  • Such support may through the present invention be obtained by the heel section of the sole of the footwear being deformed and depressed for relatively to bring the section under the foot curvature/foot arch of the sole upwards for supporting the foot curvature/foot arch.
  • the deformation will normally be achieved by a load on the sole with a weight from a normal person (25-120 kg depending on the age, build, etc.).
  • the present invention has provided a sole with simultaneous supportive, shock-absorbing and stabilizing properties with support to the foot arch in the down-step.
  • the present invention concerns, as mentioned, the construction of a sole providing support for the foot arch when loading the heel section.
  • the sole is constructed with layers, where the sole comprises a continuous material running from the outer section of the sole (the external sole/sole bottom) against the ground, and in towards the internal additional layers of the sole.
  • additional layers comprise a bracer (middle layer) running from the heel edge or the heel edge area of the sole and over up to about half of the total length of the sole.
  • the interior of the sole in the heel section has an impact cushion included facing towards the heel of the user and lying above the bracer, said impact cushion being constructed of a material being softer than the sole material.
  • the soft and inside the sole internal material is an optionally shock-absorbing material.
  • a layer lies "mainly” within or “about” a section or overlaps "mainly” or “about” another section means that there ma be present a deviation of up to 20% of the accurate measurements and preferably within 10% of the accurate measures.
  • a sole for a footwear may normally have a length from 10 cm (baby shoes) to 35 cm or more (adult footwear of full size)
  • the expression that the bracer runs "mainly” from the rear edge of the sole to substantially half of the length of the sole will mean that the bracer of a sole with the length of 35 cm may start from the exact rear edge of the sole and up to 7,0 cm from the rear edge of the sole and run to exactly half of the sole of the sole and up to 7,0 cm from the exact half of the length of the sole, and will preferably start at the exact read edge of the sole and up to 3,5 cm from the rear edge of the sole and run to the exact half of the length of the sole and up to 3,5 cm from the exact half of the length of the sole.
  • edge area means an area running from the exact edge of the sole and inwards of the sole surface in a radius of up to 2 cm.
  • An “edge area” ma include an area of 0,2-2,0 cm such as 0,2, 0,5, 0,7, 1,0, 1,2, 1,5, 1,7 or 2,0 cm from the edge of the sole.
  • foot arch means the area of the sole running from about one third from the rear edge of the sole of the relevant footwear to about two thirds from the rear edge of the relevant footwear.
  • the expression "thread surface” of the sole means an area comprising the entire internal surface of the sole to a surface being shaped as a footprint that may run across mainly the entire length of the sole.
  • a sole according to the invention may e.g. be mounted on a leisure shoe such as a jogging shoe, a shoe for walking, a sandal, etc.
  • PU polyurethane
  • TR technical rubber, synthetic rubber
  • this material 1 there are, numbered from the top (from the inside of the footwear), located an isolating and pressure-distributing material in the form of a stepping surface 2 that may be 1-10 mm thick, e.g. 6 mm thick and that covers mainly the entire threading surface of the foot.
  • the material in the threading surface 2 may be PU, HGP (a polyurethane-based material) or latex or "Poron".
  • HGP a polyurethane-based material
  • Poron latex
  • the sole in fig. 1 is divided into three sections namely a heel section H, a middle section M and a front foot section F.
  • the sections are shown to be equally large in the figure, but may overlap with each other as explained supra.
  • the foot arch will normally lie in the middle section M of the sole.
  • a shock-absorbing material 4 that may be compacted ands springs back when walking and running.
  • This shock-absorbing material 4 is located underneath the binding sole 3, completely adjacent or at a distance from this, e.g. at a distance of 0-25 mm, such as 1, 2, 3, 5, 7, 10, 12, 15, 17, 20, 23 or 25 mm from the binding sole and optionally in such a way that there is created a mass of sole material 1 between the shock-absorbing layer 4 and the binding sole 3.
  • This rigidity-supplying layer runs mainly from the rear edge of the heel section H and forwards to substantially the center of the middle section M.
  • the sole material ma in one embodiment form a "wall" assisting the side stability of the sole.
  • the breadth of the bracer 5 in the sole according to the invention lies normally in the interval 30-60% of the breadth of the sole, even if breadths beyond this interval also may be used such as a lower breadth of 10% of the breadth of the sole and up to 100% of the breadth of the sole. In normal footwear the breadth of the bracer 5 will lie in the order of magnitude of 4-8 cm, and will normally be formed as a rectangle (although also other shapes may be possible).
  • the material of the bracer 5 will generally be a rigid material, e.g. metal (steel) or hard plastic.
  • the breadth of he pliant and shock-absorbing material 4 will correspond to the breadth of the bracer 5 or it may be broader than the bracer 5, such as 0-5 mm broader than the bracer 5, e.g. 0,5, 1, 1,5, 2, 2,5, 3, 3,5, 4 or 4,5 mm broader than the bracer 5, wherein this breadth reaches beyond the bracer on each side thereof in symmetrical or asymmetrical manner.
  • the soft and shock-absorbing material 4 runs mainly from the rear end of the bracer 5 and up to about two thirds of the length of the bracer.
  • a thickness of the sole material beneath the shock-absorbing material in the toe area may lie within the interval 0,5 cm and up to the entire thickness of the sole, e.g. in the area 0,5-2,5 cm if the thickness of the sole is 2,5 cm.
  • the sole may also be relevant optionally to equip the sole with an external layer of a more rigid material of rubber or plastic (see Fig. 2 ).
  • a more rigid material of rubber or plastic see Fig. 2 .
  • the sole may thus be 0,5-10 mm broader in its lower surface (towards the ground) than in its threading surface (towards the foot).
  • the upper side (cover surface) of footwear with a sole according to the present invention may be selected from conventional materials and designs. Normally there will be used an upper side of leather or a synthetic material.
  • This example concerns a sandal with a sole with a maximum thickness of 50 mm beneath the heel-middle foot section and with a sole constructed in accordance with the invention.
  • the sole material 1 of this sole is made of a polyurethane (PU) material wherein a binding sole 3 of "Texon” and with a thickness of 2 mm is glued to the PU sole material 1, and wherein an inner sole 2 being made of "Poron” and with a thickness of 5 mm being fastened to the upper surface of the binding sole 3.
  • PU polyurethane
  • a layer of a shock-absorbing material 4 (HGP material) with a thickness of 5 mm.
  • HGP material a shock-absorbing material 4
  • the breadth of the shock-absorbing and resilient material 4 equals the breadth of the bracer 5 and is about 50% of the breadth of the sole.
  • This example concerns a sole for a running shoe where the sole is constructed correspondingly to the sole in example 1, however with the addition that the sole in its edge area from the rear heel section and forwards to the middle section of the foot (about half of the length of the shoe) is equipped with vertically descending edges of a firmer latex material than the sole material (PU material) for providing additional side stability to the sole.
  • the upper side of the shoe is here made of a synthetic water-repellent material with airing holes covering the entire foot.
  • This example concerns a sole for a leisure/walking shoe that also may be used as a running shoe, where the sole is constructed as in example 2, but with the additional feature that the underside of the sole is 5 mm broader than the breadth of the rest of the sole.
  • This example concerns a sole for a leisure/walking shoe that also may be used as a running shoe, where the sole is constructed as in example 1, but with the additional feature that the underside of the sole is 5 mm broader than the rest of the breadth of the sole, and that the breadth of the shock-absorbing material is 3 mm broader than the bracer on each side of the bracer.
