Definitions

  • the present application relates to a midsole, particularly for shoes.
  • the convex conformation of the midsole is indicated as the characteristic which may prevent malfunction of the skeletal-muscular system and maintain correct posture of the spinal column.
  • Patent US2009/056165A1 is also known, illustrating an improvement on the previous solution wherein in the heel region there is a seat with elastically compressible elements; this solution too presents the same drawbacks as mentioned above.
  • Patent W02009/061103 is also known, illustrating an improvement on the previous solution wherein a front insert and a rear insert are present which can be positioned in seats adjoining a central protrusion projecting downwards; such solution also has drawbacks in that it is composed of multiple components which increase its structural complexity and thereby cost.
  • the main object of the present invention is therefore to overcome the technical problems described, eliminating the drawbacks of the prior art mentioned and therefore devising a finding which makes it possible to produce a midsole, particularly for shoes, which is structurally simple and composed of a limited number of components, the same being adaptable in a rapid and simple manner to the specific requirements of the user so as to find ample application while industrially manufacturing a single product per size.
  • another important object of the invention is to make a midsole which forces the user to adopt a constantly erect position and which, at the moment of walking, solicits the muscles all over the body so as not to burden solely the back muscles.
  • Another object of the invention is to make a midsole wherein during the rolling motion of the step, the foot, and in particular the metatarsus region, is not strained during such movement.
  • Another object of the invention is to permit activation of the small muscles responsible for stabilising the joints so that the skeletal muscular system imposes a postural adjustment by the user.
  • Another no lesser object is to obtain a device which has limited production costs and which can be made in the usual prior production plants.
  • a midsole particularly for shoes comprising a lower surface which has an arc-like shape with the convexity directed toward the ground, characterised in that it has an upper surface on which there is, in the region between the tarsus and metatarsus, a longitudinal seat for at least one elastically compressible insert which can be positioned detachably thereat.
  • reference numeral (1) denotes a midsole, particularly for shoes, not shown, which may comprise a footbed advantageously divided into a pair of insoles (2a, 2b) advantageously of the ergonomic type and made in soft material to recreate the conditions of a pliant ground surface making walking more physiological, the same being placed to affect the regions (3) of the heel and the toe.
  • Such shoes also comprise a sole (5) which may be made from rubber or other plastic material.
  • the midsole (1) is made from plastic material and must enable a distribution of the load from the weight of the foot upon it, at least in the region (6) between the tarsus and metatarsus, corresponding approximately to that of the plantar arch; such midsole (1) may be made from a semi-rigid plastic material.
  • the midsole (1) there is an upper surface (7) in the heel region (3) and toe region (4) of which the pair of insoles (2a, 2b) is associated and, in the region (6) between the tarsus and metatarsus there is at least one seat (8) which affects, in a longitudinal direction, part of the length of the midsole (1) approximately up to the heel region (3) and toe region (4).
  • Such seat (8) has longitudinal edges (8a, 8b) which advantageously follow the shape of the adjacent edge (9) of the midsole (1).
  • the seat (8) has transverse edges (10a, 10b) of different width, the width of the edge directed toward said toe region (4) being greater.
  • the insert (11) is therefore located in a region (6) which corresponds to the region of the centre of gravity of the foot of the user.
  • the insert (11) is substantially shaped complementarily to the seat (8) which has, preferably, at the transverse edges (10a, 10b), temporary engagement means for complementarily shaped grip means present or associated with said at least one insert (11).
  • the temporary engagement means are composed of a pair of elastically deformable transverse tabs (13a, 13b), which retain the insert (11) in the seat (8) and which thereby snap-insert it into such seat (8).1
  • the grip means are in fact constituted by the resting surface of the edges of the insert itself, other embodiments of such means also being possible, for example, grooves or projections interacting temporarily with said engagement means.
  • the temporary engagement means may, alternatively, be made or be present on the longitudinal edges (8a, 8b).
  • the insert is elastically compressible but at the same time rigid enough to create a centre of pressure towards the plantar arch, so as to determine a sensation of instability in the user as shown in figure 6 , as if, for example, the user were standing with the arch of the foot, and therefore the centre of gravity of the foot, resting on a round sectioned rod acting as an element on which the foot pivots.
  • a region (14) having constant dimensions is formed in which the surface (5a) or surface (5b) interact with the sole: in the intermediate condition, in which the region (14) is substantially at the region (6) between the tarsus and metatarsus, all the weight of the body pivots on the centre of gravity passing through said region (6) between the tarsus and metatarsus: the pressure of the weight of the body acting in the point of the centre of gravity imposes a constantly erect posture which at the moment of oscillation solicits the muscular system of the entire body so as not to burden only the back muscles.
  • the insert (11) being elastically compressible, absorbs the various pressures on the foot in the point of the centre of gravity and thereby prevents the region (6) between the tarsus and metatarsus from being strained by the movement.
  • the interchangeable nature of the insert (11) makes it possible to customise the midsole depending on the weight of the user.
  • the invention accomplishes the aforementioned task and objects, a midsole having been created which is structurally simple in that it is composed of only two elements, the substitution of the insert according to the weight of the user making it possible to adapt the midsole quickly and easily to the specific requirements of the user so as to find a wide range of application while industrially producing a single product for each size and a multiplicity of inserts of varying rigidity or elasticity.
  • a midsole has been made which forces the user to adopt a constantly erect position and, when walking, solicits the musculature of the entire body so as not to burden exclusively the back muscles, and further during the rolling motion of step, the foot, and in particular the metatarsus region, is not strained by such movement.
  • the midsole enables activation of the small muscles responsible for stabilising the joints so that the skeletal muscular system provides for a postural adjustment by the user, the invention having limited production, storage and transport costs.
  • the insert is concealed inside the midsole so as not to alter the external aesthetic configuration.
