Abstract

A combined pronation and supination control plantar insert for shoes comprising posture control elements adapted to correct and/or modify the posture of the entire tendon, bone and muscle structure of the body, both laterally and medially and both for talipes equinus and for talipes calcaneus. The plantar insert allows to correct the main postural defects involving mastication, cervical structures, the spinal column, hips, ankles and feet.

Claims

1. A combined pronation and supination control shoe plantar insert for controlling posture of a user body, comprising a base element and posture control means for correcting and modifying the posture of the entire tendon, bone and muscle structure of the user body, said posture control means comprising at least one element which is movable transversely with respect to a longitudinal axis of said base, in a plane which is parallel to a plane in which said base is defined, said at least one element being adapted to vary the height of the user at a hindfoot, in a medial and lateral region of the foot, the plantar insert further including a heel region extending along a longitudinal axis thereof, at which said posture control means are located, said heel region comprising:

a rigid base which has a perimetric ridge forming a pair of first arc-like lateral wings;

a second wing;

a first wall being perpendicular to said base and lying on an axis which is substantially transverse to the axis of said heel region;

said first lateral wings joining in a rear region of the base with said second wing which has a concave upper surface connected to said base by way of said first wall.

2. The plantar insert of claim 1, wherein said posture control means are located at any of a hindfoot, midfoot and forefoot region of the foot of a user.

3. The plantar insert of claim 1, including a heel region extending along a longitudinal axis thereof, at which said posture control means are located, said heel region comprising:

a rigid base which has a perimetric ridge forming a pair of first arc-like lateral wings;

a second wing;

a first wall being perpendicular to said base and lying on an axis which is substantially transverse to the axis of said heel region;

said first lateral wings joining in a rear region of the base with said second wing which has a concave upper surface connected to said base by way of said first wall.

4. The plantar insert of claim 3, wherein said first wall and said second walls have tips which protrude beyond an upper perimetric edge of said first lateral wings, so as to form guiding seats for said at least one element which is adjustably movable with respect to said base.

5. The plantar insert of claim 4, wherein said at least one element comprises an outer lateral surface which has a step-like discontinuity, said discontinuity being shaped complementarily to said fist lateral wings, dimensions of said at least one element being such as to allow the element to slide laterally and medially as well as vertically between said first wall and said second walls, respectively, of said second win and of said third wings.

6. The plantar insert of claim 5, wherein each one of said at least one element has an internal lateral she which is shaped arc-like and joins with said concave upper surface of said second wing so as to constitute supporting regions for an overlying part of the user foot.

7. The plantar insert of claim 6, comprising at least one pair of set screws, and complementarily threaded seats formed transversely to said first lateral wings along an axis being offset with respect to an axis that runs transversely to said heel region;

position adjustment of said at least one movable element with respect to said base being provided by way of said at least one pair of set screws which ate freely rotatably associable at said suitable seats.

8. The plantar insert of claim 7, comprising threaded seats formed at facing outer lateral surfaces of said at least one element, said screws being partially rotatably associated at said complementarily threaded seats so as to allow sliding of said at least one element with respect to said base.

9. The plantar insert of claim 8, wherein said first wall and said second walls are inclined with respect to the axis which runs transversely to said heel region.

10. The plantar insert of claim 9, wherein said screws are positioned so as to be in any of a perpendicular and inclined position, with respect to said outer lateral surfaces of said at least one element.

11. The plantar insert of claim 1, comprising two third wings, said first lateral wings being connected, in a front region of the base, to said two third wings which are further connected to said base, so as to form second walls, said second walls being arranged at an angle with respect to an axis which lies transversely to said heel region.
