Definitions

  • the present invention relates to an improved footwear sole in particular a generic shoe.
  • Soles generally consist of a single material all along the sole of the foot which does not vary in density. Despite this, from a bio-mechanical aspect two different types of pressure are exerted on the sole and heel so that the system is not optimised for movement of the foot or the absorption of impact.
  • Footwear is known of, for example, such as that described in the application EP10152804 which by means of special inserts make the foot slightly unstable when resting on the ground.
  • EP10152804 which by means of special inserts make the foot slightly unstable when resting on the ground.
  • the user's body is forced to use, and therefore train, a significant part of the musculature otherwise at rest, such as calves, buttocks, quadriceps, etc.
  • the user exercises unconsciously in a relatively fatigue-free manner.
  • the efficacy of such solution has been shown experimentally.
  • the main object of the present invention is to extend the prior art, offering a sole with improved, and even different, abilities to stimulate a muscular reaction of the body without being subject to fatigue and/or without undertaking a physical exercise routine.
  • Another object is to obtain a sole which promotes muscular stimulation even in the absence of physical exercise, even during a merely erect posture.
  • the sole according to the invention has a sandwich structure comprising:
  • a sole 20 The front of a sole 20 is partially visible in fig. 1 .
  • the sole will be considered as positioned when in use, so that the part in contact with the ground is the bottom part.
  • the sole 20 comprises an upper layer 22 which has seats or concavities housing four deformable inserts 24,26,28,30 with zero backlash.
  • the inserts 24,26,28,30 are positioned roughly symmetrically around a longitudinal axis X of the sole 20, are distanced from each other and project a certain distance from the layer 22.
  • the inserts 24,26,28,30 are islands of different material glued into the layer 22.
  • the layer 22 is preferably coupled underneath to an intersole (not shown) .
  • the inserts 24, 28 are larger than the others, drop-shaped and are positioned alongside the sole of the foot.
  • the inserts 26, 30, smaller and of a roughly oval shape, are positioned alongside under the toe of the foot.
  • the inserts 24,26,28,30 are entirely covered by a layer 32 which comes into contact with the ground.
  • the layer 32 is a rubber strip glued onto the inserts 24, 26, 28, 30.
  • the layer 32 extends over the layer 22 even in the areas between the various inserts 24,26,28,30 and in these areas is locally glued at anchorage points GL.
  • the layer 32 or parts of it can thus freely oscillate in relation to the layer 22 along a plane (see diretrix D or G in fig.1 ) roughly parallel to the layer 22, thanks to the deformation of the inserts 24,26,28,30.
  • the effect is shown in figures 4 and 5 , where a complete shoe 40 is shown which uses the sole 20.
  • the part of the shoe 40 which rests on the ground is, on the front part, the layer 32 which can flex on the inserts 24, 26, 28, 30.
  • the foot of a person wearing the shoe 40 is hugged in the upper and rests firmly on the layer 22 (for example by means of an intermediate intersole).
  • the layer 22 Between the part resting on the ground consisting of the layer 32, and the layer integral with the foot, the layer 22, are the inserts 24, 26, 28,30. These can mechanically deform laterally (along the directrix D and G). Consequently the areas of the foot overlying the inserts 24,26,28,30 do not have a stable support on the ground but can constantly "vibrate" to the right or left, backwards or forwards, often alternately.
  • the user's body detects these micro shifts in position and to restore stability activates the muscles needed to re-establish balance. Constant, unconscious training results which tones the musculature.
  • the inserts 24,26,28,30 are also elastically compressible vertically, in other words orthogonal to the ground .
  • the inserts 24, 26, 28, 30 also permit a vertical movement, in that they do not only "oscillate” in relation to the base element 22, but also compress and dilate thanks to the characteristics of elasticity and impact absorption.
  • An boosted effect of induced muscular mobility results for the person wearing the footwear.
  • a sole 42 In fig. 6 the rear part of a sole 42 is partially visible which at the front may be like the sole 22, for example.
  • the sole 42 has a sandwich structure like the sole 20, and comprises an upper layer 50 which has seats or concavities which a single deformable heel insert 52 of a round shape is housed in without play.
  • the insert 52 is positioned in the centre of the sole 42, under the heel.
  • the insert 52 is entirely covered by a layer 54 which comes into contact with the ground.
  • the layer 32 is a rubber strip glued onto the insert 54, and there are no points of contact, and therefore attachment, between the layer 54 and the layer 50.
  • the layer 54 can freely oscillate in relation to the layer 50 along a plane roughly parallel (see directrix D2 or D3 in fig.6 ) to the layer 50 thanks to the deformation of the insert 54.
  • the effect is shown in fig. 9 and 10 , where a complete shoe 50 is shown which uses the sole 42.
  • the support point of the shoe 60 is, on the rear part, the layer 54 which can float on the insert 52.
  • the foot inside the shoe 60 is hugged by the upper and rests firmly on the layer 50, while in the ground support, consisting of the layer 54, the insert 52 is interposed.
  • the latter may mechanically deform so that the foot can oscillate over the layer 54 (arrow H).
  • the foot does not have absolute stability and to impose it must activate the muscles needed for equilibrium.
  • the insert 52 is also elastically compressible vertically, in other words orthogonally to the ground. This way it also permits a vertical movement of the foot in that it compresses or dilates. A boosted effect of muscular mobility results for the person wearing the footwear.
  • the front or rear parts of the sole described permit a toning effect of legs and buttocks by simply walking, even more so if the two structures described are combined in a single sole.
  • the deformation of the inserts is preferably of an elastic type, that is they return to their original form once the phase of pressure of the foot has finished.
  • the base which an insert and the membrane or layer covering it lie on may be made with known materials used in the footwear sector such as generally rubber. It is the inserts, preferably in PU, which determine the characteristics of the sole. All the inserts described are positioned in the points of maximum pressure of the foot during the various phases of walking, adapting to the rolling phases and areas of bending.
  • a space or channel 46 may be associated with the sole 20 which divides the sole or element 22 into two parts roughly along the axis X. Each part houses an insert under the sole of the foot and a toe insert.
  • the channel 46 allows the sole 20 to distance itself slightly outwards (by several mm or fraction of millimetre) along the directrix D, a movement which makes the two pairs of inserts move away from each other and enables maximum comfort of the foot during the phase of maximum pressure on the sole which naturally tends to widen.
  • the channel 46 may also take the form of a simple groove, tunnel, recess in the sole or incision of the sole.
  • Fig.11 shows a variation 80 of the sole 20, to be compared to figure 2 .
  • the inserts here indicated by reference numeral 84, are not coupled to the layer overlying the base 86 but, by means of the apertures or windows in the layer 86, directly to an intersole 88.
  • a layer or element for contact with the ground 82 is coupled to and covers the inserts 84.
  • the sole 80 is identical to the previous one, but is lighter thanks to the reduction of material in the layer 86. The same concept can be applied to the sole 42.
  • the inserts placed under the sole of the foot and the inserts in the heel are of variable density to each other to better follow the biomechanics of the walk.
  • a different type of PU can be used for each insert.
  • each insert may in itself be of varying density, to increase the spatial resolution and precision of the shock absorbing action.
  • a type of PU can be used which varies its density within the insert itself.
