Definitions

  • This invention relates to footwear, in particular to a novel type of sole unit and to shoes, sandals and slippers manufactured therefrom.
  • Shoes, sandals and slippers having soles substantially of wood that has been shaped to conform to the sole of the foot have become popular in recent years.
  • the sole unit of the shoe has a heel cup, a raised portion under the arch of the foot, depressions under the metatarsal heads of the big and little toes and a ridge (or gripper bar) just ahead of the front transverse arch to support the toes, especially the four small toes.
  • a shoe in the form of a slipper with a strap across the metatarsal heads of the toes encourages the wearer to move his toes while walking and grip the ridge or gripper bar, and this exercise massages the foot and also the leg muscles.
  • a sole unit of this type is described in British Patent Specification No. 877,365.
  • Sole units for comfortable shoes and for sandals are already known in which the sole unit consists of two different materials of different hardnesses.
  • shoes and sandals have been manufactured with a sole block of relatively hard wood and, below it, an outsole of relatively soft polyurethane foam having the same circumferential shape as the sole block.
  • this type of sole unit suffers from all the four disadvantages mentioned above.
  • various shoes are known where the sole unit is composed of two different polymeric materials, for example a hard pulyurethane shell forming an outsole having an edge piece to which the upper can be fastened, whereas a soft polyurethane foam forms the "sole block".
  • a sole unit for a shoe or sandal or slipper having a toe portion, a shank portion and a heel portion including a heel cup
  • said sole unit being of at least two materials of different hardness, of which a softer and flexible material forms an outsole and a harder and relatively inflexible material forms a sole block, wherein the harder material forms the heel cup region and a region of the shank portion supporting the outer longitudinal arch of the foot, and the sides of the heel and the area under the main longitudinal arch of the foot are formed by the softer material, the upper surface of the softer material being of a relatively high contour under the main longitudinal arch of the foot so as to support and to massage the main longitudinal arch favourably in walking.
  • the sole block preferably extends from the heel through the shank region into the toe region.
  • a sole block can conveniently have its upper surface shaped to the contour of the foot.
  • the sole unit can have a heel cup, a shank portion to support the longitudinal arches, depressions for the metatarsal heads of the big and little toes, and a rounded ridge (or toe barrier) as a gripping bar for the four small toes, all preferably formed in the sole block.
  • Both the softer and the harder materials can if desired be of synthetic, polymeric material.
  • the softer material can be of soft polyurethane foam or of thermo rubber or of polyvinylchloride, and the harder material can be of hard polyurethane.
  • the softer material is preferably of soft and flexible polyurethane foam and the harder material is preferably of wood, in particular a high-quality wood such as poplar or especially beech.
  • the softer material preferably has a Shore hardness of 45 to 60, and the harder material may for example be one having a Shore hardness of at least 60, e.g. 60 to 100, preferably 60 to 75.
  • Beech for example can conveniently have a Shore hardness of 60 to 95, whereas a sole block formed of polymeric material can conveniently have a Shore hardness of 60 to 80.
  • the harder material is preferably absent under the longitudinal arch so that the softer material can fill this space and better accommodate itself to pressure under the arch.
  • This softer material is preferably set relatively high under the arch so that the arch will come into contact with it during walking and will thereby be massaged by it. This has a very healthy effect upon the muscles and ligaments associated with the region of the arch of the foot. As the softer material yields under the arch, it will not be uncomfortable during walking, even if the wearer's arch is relatively low.
  • the softer material preferably extends all the way around the harder material, even around the toe region of the foot. This can have two advantages: the softer material will be less dense than the harder material and the sole unit is correspondingly lighter; and any tendency of the edges of the harder material, if made of wood, to splinter or split will be strongly reduced.
  • a further advantage of continuing the softer material all around the harder material is that the whole shoe under these circumstances can be made antistatic. It has been seriously suggested that static electricity can cause or aggravate various diseases.
  • the side part formed of the softer material must be wide enough for at least part of the skin of the heel of the wearer to rest upon the softer material, which will of course yield more than the harder material in walking. For this reason, the new design of sole unit will tend to reduce callus formation at the heel.
  • the sole unit 1 of Figs. 1 - 3 consists of a toe portion 2, a shank portion 3 and a heel portion 4. It is made of a sole block 5 of wood, having a heel cup 14, a depression 15 for the metatarsal head of the big toe and another depression 16 for the metatarsal head of the little toe.
  • the rounded ridge or gripper bar 17 just forward of the metatarsal heads of the four small toes is indicated in section in Fig. 2 and by a broken line (showing its crest) in Fig. 1.
  • the general line of the main longitudinal arch of a foot is shown at 8.
  • the sole unit 1 is designed so that most of the arch of the foot will be situated over and supported by the .softer material, namely polyurethane foam, which is raised progressively from the level of the sole block 5 in the direction of the inside edge of the sole unit 1.
  • a supporting slope 9 is provided as shown especially in Fig. 3, to massage the arch of the foot during walking.
  • the polyurethane foam completely surrounds the edges of sole block 5 as shown in Fig. 1 It should in any case extend around the heel at least from point A to point B, preferably to point C. Forward of points A and C, that is over the areas A-E, and C-D, a simple supporting strap (not shown) can be attached to provide a foot-exercising sandal.
  • the polyurethane at the areas A-E and C-D where the strap is attached may be cut away to provide recesses to receive the ends of the strap, so that the strap itself does not protrude from the side of the sandal. Alternatively, such recesses to accommodate the ends of the strap can be produced during manufacture by injection moulding.
  • the new type of sole unit 1 is preferably manufactured from a thin block of wood as sole block 5 having a flat lower face 6 as clearly shown in Fig. 2.
  • the sole block 5 must be shaped around the sides and on the top surface only; in this way the wood is economically used and processed, since there is very little wastage and relatively little working to do.
  • the sole block 5 can then be placed inside a mould and the polyurethane can be injected around it in known manner. Usually this method is highly advantageous since, under these circumstances, the polyurethane forms a very good and lasting bond to the wood.
  • the surfaces of the hard material (forming the core) and of the soft material (forming the edge around the heel, the massaging part under the main longitudinal arch and preferably an edge around the toe portion and the remainder of the shank portion) should meet flush at their junction, so that neither material has an upstanding edge and so that the surface at the junction in general forms a smooth curve without discontinuities. Any shrinkage or swelling of one or the other material that may occur should either be very low or otherwise be allowed for in the manufacturing process.
  • the finished sole unit 1 can then be made into a shoe in known manner by attachment of an appropriate upper.
  • the upper can be attached to the sole block 5 (for example under its lower face 6) and the polyurethane can be injected around it to secure it thoroughly.
  • the sole unit for a left foot is of course simply a mirror image of the sole unit for the right foot illustrated e.g. in Figs. 1 - 3.
