Definitions

  • the subject of the present invention is a support device for a foot in a sports and / or leisure shoe, and a method obtaining this device.
  • orthopedic insoles are intended to modify the balance of the articular chains by recreating arches which are collapsed.
  • Such soles, called corrective, are used very little for the practice of sport, because they are traumatic.
  • proprioceptive incorporate extra thicknesses intended to stimulate or inhibit plantar receptors and change parasitic muscle tension or imbalance posturostatique.
  • Document FR-A.2286 638 relates to a sole orthopedic to correct the internal rotation of the feet in young people children.
  • This sole has a first wedge extending at the level of the proximal part of the first metatarsus and behind that part and a second corner extending in the extension of the first, towards the rear of the sole, always on the side of the inner edge thereof. It comes in a such case to exercise a permanent corrective action.
  • Document US-A.2 884 719 describes a sole or a device integrated into a shoe intended to treat metatarsalgia in trying to distribute the loads to avoid a too punctual support.
  • This device includes a wedge extending in the central and proximal area of the first metatarsus as well as in the proximal parts of the second and third metatarsus.
  • Document US-A.2 660 814 describes a shoe sole aimed at distributing the loads by implementing a large number of holds, including essentially a hold under the first three metatarsals and a horseshoe-shaped wedge supporting the arch and surrounding the outside of the heel.
  • thermoformable insoles called physiological, and molded directly on the foot, much appreciated on the sporting plan, because they increase the support surface and therefore give a greater comfort.
  • prono-supinator This biomechanical movement of the foot, called prono-supinator, is accompanied by a rotation of the leg axis formed by the tibia and the fibula.
  • the supination causing the external rotation of the leg skeleton and pronation causing internal rotation of the leg skeleton, balance between these rotations and the counter-rotation generated by the ground support is mainly regulated by the long lateral peroneal muscle.
  • the object of the invention is to provide a support device for a foot in a sports or leisure shoe, which is not intended to correct a form of foot but to brake and control a pressure bearing gradually over a specific area of the foot.
  • the device which it relates to includes combination a suspension element arranged in the area used to the support of the distal end of the first metatarsal head of the foot and a transverse suspension element, placed in the mid-tarsal area, enveloping the anterior part of the heel.
  • suspension element used for the support of the first metatarsal head is arranged in the area serving more precisely in support of the phalango-bisesamo ⁇ dien cradle in which articulates the first metatarsal head encrusted with cartilage.
  • this element suspension function is to control the pressure of the foot and control the sag of the forefoot when the support is carried during the pre-propulsive phase, to relieve the long lateral peroneal muscle and keep it effective.
  • suspension elements do not concern not the lateral metatarsal rays which constitute the braking zone kinetics of the foot, but only the first metatarsal ray which is the the only propellant and the only one with active plantar flexion.
  • the presence of a suspension element in the mid-tarsal area enveloping the anterior part of the heel allows, in association with the suspension element located in the support area of the distal end of the first metatarsal head, to realize the tensioning of plantar fascia by dorsiflexion of the big toe, known as name of "Windlass Mechanism". This results in a facilitation of the passive locking and increased support surfaces.
  • the suspension elements have a thickness of the order of 2 to 8 mm and are made of a flexible viscoelastic or elastic memory material, such as, for example, Ethylene Vinyl Acetate EVA with a shore hardness of between 20 and 50 and of a density greater than 70 kg / m 3 , or of polyethylene with a shore hardness between 60 and 140 and a density greater than 100 kg / m 3 .
  • EVA Ethylene Vinyl Acetate
  • polyethylene with a shore hardness between 60 and 140 and a density greater than 100 kg / m 3 .
  • suspension elements are not traumatic and may be suitable for different foot shapes of the same size, they can be compatible with an industrial production system, that the suspension elements are arranged on the underside of a shoe insole or on the upper side of the bottom of a shoe.
  • the density and thickness of the suspension elements are chosen according to the size, the activity practiced and possibly the weight of the user.
  • the support device in the case of a golf shoe, can be completed with a suspension element mediotarsal extended along the inner edge of the heel to promote postural balance and hip placement, and to guide the transfer load during the transition from adaptive eversion to inversion of stiffening.
  • the suspension elements can also be arranged on the upper side of the sole, or on the bottom of the shoe, on the upper face of the latter or on its lower face bearing on the ground.
  • the suspension elements can be made up not by a flexible material, but by suspended areas of a sole preformed.
  • the suspension element has a groove longitudinal for housing the long flexor proper of the first toe.
  • the process for obtaining the support device as mentioned above includes the step of molding this device on the foot of the user or on a form reproducing this foot.
  • Figure 1 shows a sole, designated by the reference general 2, made, for example, of a thermoformable material for adopt the general shape of the underside of a foot and ensure satisfactory support thereof.
  • this sole has a suspension element 3 in the zone intended for serve as support for the distal end of the first metatarsal head 6 of the foot.
  • This suspension element 3 more specifically serves to support the phalango-bisesamo ⁇ dien cradle in which the first head is articulated metatarsal.
  • This suspension element is made of a material flexible with elastic memory, to quickly return to its original shape after being compressed. The thickness of the suspension element is in the range of 3 to 6 mm. Given its flexibility, this element of suspension does not affect the comfort of the shoe fitted with such a sole.
  • the suspension element arranged under the sole can be made of EVA or polyethylene, for example, whose densities have been indicated above.
  • the sole shown in Figures 1 to 3, which is particularly suitable for equipping a shoe for practice golf course, also includes a transverse suspension element mediotarsal 4 enveloping the anterior part of the heel under the median axis of the foot, provided with an extension 5 towards the rear of the inner side of the heel.
  • This suspension element 4, 5 combined with the suspension element 3 promotes postural balance and movement of the hips and directs the charge transfer during the transition from adaptive eversion to the inversion of stiffening by ensuring the tensioning of the fascia plantar by dorsiflexion of the big toe.
  • the suspension element 3 anticipates and limits the overload of the foot during the pre-propulsive support phase and keeps the long muscle peroneal lateral all its effectiveness, and avoids ligament irritations and tendon due to muscle fatigue which can manifest under form of cramps.
  • suspension elements 3, 4 do not concern the 2 nd to 5 th metatarsals 8 and therefore do not intervene on the corresponding kinetic braking zone.
  • Figures 4 to 8 show another sole in which the same elements are designated by the same references as previously.
  • the suspension element 4, 5 is located on the upper face of the sole, and a damping element 9, known per se, is placed under the sole at the heel.
