Description

Technical Field

[0001] This invention relates to the field of footwear, and more particularly to a walking sole configured to receive at least one stability compensation overshoe, and a shoe comprising such a walking sole and such stability compensation overshoe. Background Technology

[0002] Gait and balance disorders are common in older adults and are associated with aging of the gait and balance effectors, which are linked to several diseases and their treatment. The combined effects of aging and the onset of various age-related diseases explain the balance and gait disturbances commonly experienced in older adults. In fact, sarcopenia and age-promoted changes in muscle composition (fat cells > muscle cells) are detrimental to its function, especially because they are associated with sedentary behavior and malnutrition. Osteoarthritis, osteoporosis, and sedentary behavior, which affect the musculoskeletal system, also impair balance.

[0003] These conditions have a dual impact on older adults. On one hand, the loss of independence is directly related to these impairments; major gait disturbances can partially or completely jeopardize an older adult's independence, whether it's going shopping or performing daily activities. On the other hand, they are a cause of falls, the severity of which is known in older adults. These lead to direct consequences such as hospitalization and surgery, and secondary consequences such as loss of independence and the need for nursing homes. The causes of these gait disturbances are diverse, and the means of correcting them are typically orthotic shoes, orthotics, single crutches, double crutches, three-legged crutches, walking aids, wheelchairs, etc.

[0004] However, orthotic shoes offer only very limited improvement, and other solutions, especially orthotics, single crutch, double crutch, triple crutch, walkers, wheelchairs, etc., limit the independence of the elderly.

[0005] Several solutions have been designed to improve the stability of shoes for the wearer. For example, document EP 0,811,330 describes a shoe specifically designed for running that includes a stability mechanism. The sole of the shoe includes: an outsole; a midsole that is softer than the outsole; a heel lifter; an inner surface; and an outer surface that includes a concave, rounded portion extending downwards along one side of the sole. This concave, rounded portion comprises a portion formed by the midsole that extends below an end-side region on one side of the sole, such that its rounded portion easily deforms under the load of the user's weight during lateral movement of the sole, thereby providing better lateral stability. While this type of sole improves foot damping during athletic exercise, it does not provide a satisfactory improvement in ankle or midfoot stability.

[0006] Another solution disclosed in document WO2013 / 095709 describes a shoe having a forefoot portion, a midfoot portion, and a heel portion, and including a sole having a base layer, a heel base extending from the base layer, a lateral stabilizer base extending from the base layer and at least partially positioned below the cuboid bone, and a mid-stabilizer base extending from the base layer and at least partially positioned below the navicular bone. When the legs move, the weight of the person wearing the shoe is supported at least on the heel base, the lateral stabilizer base, and the mid-stabilizer base, thereby transferring the person's weight from the heel base to the lateral stabilizer base and the mid-stabilizer base. The heel base, stabilizer base, and mid-stabilizer base include an outsole and a compressible base layer between the outsole and the wearer's foot. Similarly, although this type of sole improves heel damping, it does not satisfactorily improve ankle or midfoot stability due to the heel base.

[0007] To overcome these shortcomings and provide stability not only during walking but also in a stationary standing position, the applicant invented a sole in French patent FR3069419B1 that includes a specific stabilizing device. In this solution, the sole includes at least one outsole comprising a convex toe, a convex top lifter, a so-called inner surface, and a so-called outer surface. The so-called inner surface extends from the top lifter to the toe of the sole on its inner side and includes a concave or straight portion at the midfoot. The so-called outer surface extends from the top lifter to the toe of the sole on its outer side and includes a concave portion at the midfoot. Furthermore, the sole includes at least two medial and lateral stabilizing elements extending from the inner surface at the midfoot and having concave edges, and a second so-called lateral stabilizer element extending from the outer surface at the midfoot and having a concave edge on the lower surface of the medial stabilizer element. When the outsole is in a straight and unloaded state, the lateral stabilizer element extends 0.5 mm to 1.5 mm below the lower surface of the outsole.

[0008] In an alternative embodiment, the central region of the sole includes a recess in which a one-piece U-shaped portion can be positioned, the one-piece U-shaped portion including an inner stabilizing element and an outer stabilizing element on its ground contact surface. However, on the one hand, this U-shaped portion affects the flexibility of the sole during stride, and on the other hand, it cannot provide sufficient stability for every individual, i.e., taking into account each person's specific deficiencies.

[0009] The shoe solutions identified in the prior art cannot correct the specific postural defects of the wearer of the shoe. In addition, this is usually done using orthotic soles, which is costly and significantly complex.

[0010] Therefore, a simple and effective solution is needed to overcome at least some of these drawbacks. Summary of the Invention

[0011] Therefore, one object of the present invention is primarily a walking sole for a shoe, the walking sole comprising a lower surface and a side surface, the lower surface comprising a heel region, a toe region, and an intermediate region located between the heel region and the toe region, the intermediate region comprising an inner receiving surface and an outer receiving surface, the inner receiving surface extending in a concave-convex manner along the inner edge of the side surface below the walking sole, and the outer receiving surface extending in a concave-convex manner along the outer edge of the side surface below the walking sole, the significant feature of the walking sole being that the inner receiving surface is configured to receive and retain an inner stability compensation overlay, and the outer receiving surface is configured to receive and retain an outer stability compensation overlay.

[0012] The term "walking sole" refers to the outermost part of a shoe that provides the necessary traction and protection to the floor surface it comes into contact with, and this outermost part may be multi-layered (ISO 20345:2021 (fr) - Personal protective equipment - Safety footwear).

[0013] The sole according to the invention allows for the correction of specific postural defects, such as pronation or supination, using stabilizing compensating oversoles attached along the inner and / or outer edges of the walking sole, while ensuring the stability of the shoe wearer. Furthermore, depending on the number and thickness of each overshoe, the sole according to the invention allows for the correction of postural defects of varying severity or importance. The sole according to the invention enables compensation of the shoe wearer's posture between the ankle and midfoot, i.e., vertical alignment with the center of gravity, thus improving ankle and midfoot stability.

[0014] Preferably, the walking sole, specifically the walking sole receiving the surface, is made of a semi-rigid plastic material.

[0015] Preferably, the peripheral edges of each receiving surface are angled (i.e., not rounded), preferably at an angle of approximately 90°.

[0016] In one implementation, each receiving surface has a angular fan shape to improve support and increase stability.

[0017] According to one aspect of the invention, the inner receiving surface includes at least one attachment portion for attaching an inner stability compensation overshoe, and the outer receiving surface includes at least one attachment portion for attaching an outer stability compensation overshoe.

[0018] The attachment portion may extend, for example, over the entire periphery of the receiving surface, or, for example, along the opposite side, to adequately attach the overshoe.

[0019] In one embodiment, the attachment portion corresponds to a surface in contact with the ground, and the surface is configured to receive an adhesive element, such as an adhesive element of the glue type, a self-adhesive element, or a hook and loop strip.

[0020] Alternatively or otherwise, the attachment portion includes one or more grooves configured to receive one or more complementary ribs.

[0021] Alternatively or otherwise, the attachment portion includes one or more ribs configured to receive one or more complementary grooves.

[0022] The cross-section of the groove-rib connection can be, for example, in the form of a dovetail, with the ribs engaging the grooves through deformation and force. The attachment components of the overshoe are deformable.

[0023] Advantageously, the inner and outer receiving surfaces are identical in shape and size, allowing the same stability compensation overshoe to be installed seamlessly on both surfaces. In other words, the same stability compensation overshoe model can be used to compensate for the sole internally or externally, making the shoe easier to use.

[0024] Even more advantageously, the inner and outer receiving surfaces are symmetrically positioned relative to the longitudinal axis of the walking shoe sole, i.e., symmetrically placed, in order to further improve foot stability.

[0025] Preferably, the inner receiving surface and the outer receiving surface each have a convex outer edge.

[0026] The present invention also relates to a shoe comprising a walking sole as described above and an upper attached to said walking sole.

[0027] The term "upper" refers to one or more parts of a shoe that cover the toes, the top of the foot, the sides of the foot, and optionally the back of the heel. For example, the upper is attached to the walking sole of the shoe by adhesive or stitching, or by a combination of stitching and adhesive (ISO 20345:2021(fr) - Personal protective equipment - Safety footwear).

[0028] Advantageously, the shoe also includes an inner stabilizing compensation overshoe attached to the inner receiving surface and / or an outer stabilizing compensation overshoe attached to the outer receiving surface.

[0029] Preferably, when the walking shoe sole is in a straight and unloaded state, the stability compensation overshoe protrudes at least 0.5 mm below the lower surface of the walking shoe sole.

[0030] A single shoe may include an inner stability compensation shoe and an outer stability compensation shoe, which may be identical or different in shape or size, and specifically in thickness, to compensate for specific postural defects, such as, for example, compensating for pronation or supination tendencies of the foot, or even short legs, while ensuring the stability of the wearer. Two shoes in the same pair may have stability compensation shoes of different thicknesses to compensate for specific defects specific to the wearer of the shoes.

[0031] In one embodiment, the walking sole of the shoe includes a first medial stabilizer element and a second lateral stabilizer element. The ground contact area of ​​the first medial stabilizer element includes an inner receiving surface, and the ground contact area of ​​the second lateral stabilizer element includes an outer receiving surface. An inner stability compensation overshoe is mounted to the inner receiving surface, and an outer stability compensation overshoe is mounted to the outer receiving surface. When the walking sole is in a straight and unloaded state, the inner and outer stability compensation overshoes protrude at least 0.5 mm below the lower surface of the walking sole.

[0032] Even more advantageously, the inner stabilizing compensation shoe is attached to the inner receiving surface via a complementary attachment member, and / or the outer stabilizing compensation shoe is attached to the outer receiving surface via a complementary attachment member.

[0033] In one implementation, the complementary attachment member is clip-on.

[0034] In another embodiment, the complementary attachment member is of the mating type.

[0035] In another embodiment, the inner stabilizing compensation shoe is attached to the inner receiving surface via an adhesive element, and / or the outer stabilizing compensation shoe is mounted to the outer receiving surface via an adhesive element.

[0036] Preferably, the adhesive element is glue, self-adhesive material, or hook and loop strip.

[0037] The present invention also relates to a stability compensation overshoe for a walking sole of a shoe, the walking sole including a lower surface and a side surface, the lower surface including a heel region, a middle region and a toe region, the middle region including at least one receiving surface, the stability compensation overshoe including a compensation portion including an outer surface and an inner surface, the outer surface being configured to contact the ground, the inner surface including at least one attachment member configured to attach the stability compensation overshoe to the at least one receiving surface by means of a mating action.

[0038] The stability-compensating overshoes according to the invention allow for the correction of specific postural defects, such as pronation or supination, depending on their attachment position under the sole of the walking shoe, while ensuring the stability of the shoe wearer. Furthermore, the stability-compensating overshoes according to the invention, depending on their thickness, allow for the correction of postural defects of varying severity or importance. The stability-compensating overshoes according to the invention allow for the compensation of the shoe wearer's posture. By extending from the ankle joint to the midfoot, i.e., vertically aligned with the center of gravity, it improves the stability of the ankle and midfoot.

[0039] According to one aspect of the invention, the compensation portion includes an outer edge oriented outward from the walking sole and an inner edge oriented inward from the walking sole.

[0040] Advantageously, the outer edge of the compensation portion has a convex shape to increase the contact surface of the shoe outward, and thus effectively increase the stability of the shoe and its wearer.

[0041] Preferably, the inner edge of the compensation portion has a concave shape to increase the volume between the receiving surfaces and between the stabilizing compensation overshoes, so as to better absorb the impact and drain liquid (e.g., water) or semi-solid (e.g., sludge) or solid (e.g., gravel) materials.

[0042] The stabilization compensation shoe can be an inner stabilization compensation shoe configured to be attached to the receiving surface located on the inside of the intermediate region, or an outer stabilization compensation shoe configured to be attached to the receiving surface located on the outside of the intermediate region.

[0043] In one embodiment, when the shoe is placed on the ground in the use position and no mechanical stress or force is applied, the compensation portion extends in a plane parallel to the receiving surface and the ground.

[0044] For example, the thickness of the compensation portion is between 0.5 mm and 10 mm to compensate for most foot posture defects based on the nature of the shoe's receiving surface.

[0045] In one implementation, the inner surface of the compensation portion is planar.

[0046] Alternatively, the inner surface may be configured to conform to the irregularities of the receiving surface to allow for stable compensation of the correct positioning of the overshoe on the receiving surface.

[0047] Preferably, the outer surface of the compensation wall includes a multi-directional anti-slip coating.

[0048] In one embodiment, at least one attachment member includes at least one edge extending at least partially around the inner surface.

[0049] In one embodiment, the compensation portion includes a single attachment member consisting of an edge.

[0050] Preferably, the edge extends on at least three sides of the inner surface.

[0051] In one implementation, the edge extends on all four sides of the inner surface.

[0052] In one embodiment, at least one attachment member includes at least one stud.

[0053] In one embodiment, the stud has a cylindrical shape with a circular cross-section.

[0054] In another embodiment, the stud has a tab or rib or flange shape or any other shape of protrusion adapted to allow connection by mating or interlocking.

[0055] In one embodiment, at least one attachment member comprises two studs.

[0056] In one embodiment, at least one attachment member includes at least one edge and at least one stud.

[0057] In one embodiment, the inner surface of the compensation portion includes at least one adhesive element.

[0058] At least one adhesive element may be protected by a removable or peelable protective layer, such as a protective layer made of a plastic material. The protective layer allows the stability compensation boot to be transported without the risk of it sticking to external objects. The protective layer is removed just before the stability compensation boot is installed onto the receiving surface.

[0059] Advantageously, at least one adhesive element is distributed on the entire inner surface.

[0060] Preferably, the inner surface of the compensation portion includes a single adhesive element.

[0061] Advantageously, the stabilizing overshoe includes a stabilizing portion that extends from the outer edge of the stabilizing portion and is configured to fit into the side surface of the walking shoe sole.

[0062] The term "outer edge" refers to the edge of the compensation portion, which will be placed on one side of the side surface of the walking shoe sole.

[0063] The stabilizing portion includes an outer surface and an inner surface, the inner surface being configured to contact the side surface of the walking shoe sole.

[0064] Advantageously, the stabilizing portion may include adhesive elements on its inner surface to securely attach the stabilizing compensation overshoe to the side surface.

[0065] Alternatively or otherwise, the stabilizing portion may include at least one mounting element configured to be fitted to a complementary portion of the side surface of the walking shoe sole.

[0066] Preferably, the outer edge of the compensation portion has a convex shape.

[0067] Even more preferably, the compensation part and the stabilizing part are made into one unit.

[0068] In one implementation scheme, the stabilizing compensation boot is integral.

[0069] Preferably, when the stabilizing compensation overshoe is attached to the receiving surface of the sole, and when the walking sole is in a straight and unloaded state, the outer surface of the compensation portion protrudes at least 0.5 mm below the lower surface of the walking sole.

[0089] An exemplary shoe 1 according to the present invention has already been... Figures 1 to 5 As shown in the image.

[0090] Shoe 1 includes a walking sole 10, an upper 20, and two stability compensation overshoes 30: Figure 5 and Figures 10 to 12 The inner stability compensation boots are marked 30-I and the outer stability compensation boots are marked 30-E to distinguish them.

[0091] Walking shoe sole 10 refer to Figure 1 The walking shoe sole 10 includes a lower surface 110 and a side surface 120 defining the lower surface 110.

[0092] refer to Figure 1 and Figure 2 The lower surface 110 includes a heel region 110T, a middle region 110M, and a tip region 110P.

[0093] refer to Figure 2 The intermediate region 110M includes two receiving surfaces 111: in Figure 2 and Figures 10 to 12 The inner receiving surface is marked 111-I and the outer receiving surface is marked 111-E to distinguish them.

[0094] The inner receiving surface 111-I extends in a concave-convex form along the inner edge of the side surface 120 below the sole of the walking shoe, and the outer receiving surface 111-E extends in a concave-convex form along the outer edge of the side surface 120 below the sole of the walking shoe.

[0095] The term "inner" refers to the inside of the shoe in the medical sense. The term "outer" refers to the outside of the shoe in the medical sense.

[0096] The inner receiving surface 111-I is configured to receive and retain the inner stabilizing compensation shoe 30-I, and the outer receiving surface 111-E is configured to receive and retain the outer stabilizing compensation shoe 30-E.

[0097] The receiving surface 111 can be at the same level as other protrusions and recesses of the lower surface 110 of the walking shoe sole 10 (e.g., Figure 11 and Figure 12 As shown in the example), or other protrusions extending relative to the lower surface 110 of the walking shoe sole 10 (such as...). Figure 1 (as shown in the example), the scope of the invention is not limited thereto. When the receiving surface 111 extends protrudingly relative to other irregularities of the lower surface 110 of the walking shoe sole 10 (e.g. Figure 1 As shown in the example), the receiving surface 111 preferably extends at a height between 0.5 mm and 1.5 mm, but the scope of the invention is not limited thereto.

[0098] Preferably, the inner receiving surface 111-I and the outer receiving surface 111-E are made of a multi-directional anti-slip material or include a multi-directional anti-slip device.

[0099] shoe upper 20 The upper 20 includes all elements of the top of the shoe 1 (the top portion of the shoe 1, above the walking sole 10), such as, for example, the forefoot piece, tongue, eyelets, laces, etc. Since the upper 20 itself is known and not the subject of this invention, it will not be described in further detail herein.

[0100] Stable compensation overshoes 30 exist Figures 3 to 12 In the illustrated example and in a non-restrictive manner, each stability compensation shoe 30 is integral.

[0101] refer to Figures 6 to 9 Each stabilizing compensation shoe 30 includes a compensation portion 310, which includes an outer edge 310A oriented outward from the walking sole 10 and an inner edge 310B oriented inward from the walking sole 10.

[0102] exist Figures 6 to 9 In the illustrated advantageous embodiment, the outer edge 310A of the compensation portion 310 has a convex shape to increase the support surface area of ​​the shoe 1 outward, and thus effectively increase the stability of the wearer of the shoe 1.

[0103] Preferably, such as Figures 9 to 12 As illustrated in the example, the inner edge 310B of the compensation portion 310 has a concave shape to increase the volume between the receiving surfaces 111 and between the stabilizing compensation overshoe 30, so as to better absorb impact and drain liquid (e.g., water) or semi-solid (e.g., sludge) or solid (e.g., gravel) materials.

[0104] Compensation portion 310 includes Figure 11 and Figure 12 The visible outer surface 311 and in Figures 6 to 9 The visible inner surface 312, the outer surface being configured to contact the ground, the inner surface including at least one attachment member configured to attach the stability compensation overshoe 30 to the corresponding receiving surface 111 of the walking shoe sole 10 by assembly.

[0105] Preferably, the outer surface 311 is a multi-directional anti-slip surface, for example, made of an anti-slip material and / or having irregularities in all directions.

[0106] exist Figure 6 In the illustrated first embodiment, the inner surface 312 is planar, and the attachment member includes a single edge 313 extending over the entire periphery of the inner surface 312, i.e., extending over the four edges of the inner surface 312 of the compensation portion 310.

[0107] exist Figure 8In another embodiment illustrated, the inner surface 312 includes two studs 314, for example integral with the inner surface 312, each stud configured to insert into a complementary port of the receiving surface 111.

[0108] Of course, different types of attachment members can be combined on the stabilizing compensation shoe 30, such as at least one edge 312 and at least one stud 314, or any other suitable type of attachment member. For example, in Figure 12 In the example, the stabilizing compensation shoe 30 includes a beaded portion 324 and two studs 314.

[0109] exist Figure 7 and Figures 9 to 12 In one illustrated embodiment, the stabilizing overshoe 30 includes a stabilizing portion 320 that extends from the outer edge of the stabilizing portion 310 in a direction substantially orthogonal to the plane of the stabilizing portion 310.

[0110] Preferably, and in Figures 6 to 12 In the illustrated implementation, the stabilizing compensation shoe 30 is integral, and the compensation portion 310 and the stabilizing portion 320 are made as one piece.

[0111] The stabilizing portion 320 is configured to fit into the side surface 120 of the walking sole 10 so as to bear against the side surface 120, thereby achieving lateral reinforcement and increasing the support surface area of ​​the walking sole 10, and thus increasing the stability of the wearer of the shoe 1.

[0112] In this example, the stabilizing portion 320 takes the form of an edge 322 having a greater height than the edge 313 of the compensating portion 310. Figure 9 ), or in the form of beaded portion 324 ( Figure 7 , Figure 11 and Figure 12 The cross-section of the bead-shaped portion has an outwardly convex shape and an inwardly concave shape that are complementary to the convex shape of the corresponding portion of the side surface 120 (i.e., relative to the compensation portion 310).

[0113] It should be noted that the illustrated example of the stabilizing overshoe 30 includes a stabilizing portion 320, which participates in the attachment member, given that the receiving surface 111 will be blocked by the assembly of both the edge 313 and the stabilizing portion 320.

[0114] Alternatively or otherwise, the attachment member may be an attachment member between the overshoe 30 and the receiving surface 111. These members may be clamping or mounting. For example, the receiving surface 111 may include one or more recesses on all or part of its periphery, and the overshoe 30 may include one or more complementary ribs configured to be positioned in the recesses to clamp the overshoe 30 onto the receiving surface 111. Alternatively or otherwise, the receiving surface 111 may include one or more ribs on all or part of its periphery, and the overshoe 30 may include one or more complementary recesses configured to be positioned in the recesses to clamp the overshoe 30 onto the receiving surface 111.

[0115] Figures 13 to 15 This represents another embodiment of the stabilizing overshoe 30. In this configuration, the stabilizing overshoe 30 is clamped to the sole 10.

[0116] The internal stability compensation shoe 30-I and the external stability compensation shoe 30-E are each clamped from one side of the walking shoe sole 10 into the elongated cavity 122, which is shaped like an aircraft wing section and has a rectangular hole 124.

[0117] The internal stabilizing overcoat 30-I and the external stabilizing overcoat 30-E each have a decorative portion 310, a stabilizing portion 320, and an arrow-shaped clip-on attachment member 330 extending orthogonally inward from the stabilizing portion 320. The attachment member 330 consists of a left portion 331 in the shape of a semi-arrowhead and a right portion 332, also in the shape of a semi-arrowhead. The left portion 331 and the right portion 332 are connected at the horizontal level of their bases, but define a horizontal slot 333 leading to the arrowhead. A distinct semi-circular material 334 is also formed at the horizontal level of the arrowhead tip on each of the left portion 331 and the right portion 332.

[0118] In order to clamp the internal stability compensation overshoe 30-I and the external stability compensation overshoe 30-E, the walking shoe sole 10 has a rectangular shell 126 formed in the middle region 110M, and two rectangular ports 124 lead to the rectangular shell.

[0119] Regardless of the implementation plan for the stable compensation shoe 30, refer to Figure 9 For example, the inner surface 312 may include adhesive elements 316 distributed on the inner surface 312 for properly adhering the stabilizing compensation overshoe 30 to the receiving surface 111.

[0120] Adhesive element 316 may be a self-adhesive material or part of a hook and loop material or any other suitable adhesive material. The self-adhesive material may be removable and reusable or durable (strong adhesive), depending on the expected service life.

[0121] In the case of self-adhesive materials, the adhesive element 316 can be protected by a removable or peelable protective layer 317, for example, made of a plastic material. The protective layer 317 allows the stabilizing compensation shoe 30 to be transported without the risk of it adhering to external objects. The protective layer 317 is removed just before the stabilizing compensation shoe 30 is mounted onto the receiving surface 111.

[0122] Preferably, to correct most postural defects, at least one stabilizing overshoe 30 is configured to protrude at least 0.5 mm below the lower surface 110 of the walking sole when the walking sole 10 is in a straight and unloaded state. This allows for primary support in the central region of the shoe 1, thereby enhancing the overall stability of the wearer of the shoe 1.

[0123] exist Figure 18 In the illustrated embodiment, the stabilizing compensation overshoe 30 has one or more holes 350 (in) Figure 18 In the example, there are two holes 350, and the shoe is attached to the lower surface 110 of the walking shoe sole 10 by through screws 360. The screws 360 allow the height of the stability compensation overshoe 30 to be adjusted depending on whether they are more or less screwed together, thereby creating a gap between the stability compensation overshoe 30 and the lower surface 110 of the walking shoe sole 10.

[0124] exist Figure 19 Another implementation shown is similar to Figure 18 The illustrated embodiment shows that the stabilizing compensation boot 30 has one or more holes 350 (in...) Figure 19 Only one of them is visible in the middle), and it is through one or more through screws 360 (in Figure 19 Only one of them is visible in the image. The screw head 360 is attached to the lower surface 110 of the walking shoe sole 10. The screw head 360 is received in a slot 100A of the walking shoe sole 10 and is freely rotatable. The screw 360 is screwed into an additional thread in the hole 350 of the stabilizing shoe 30 so that the stabilizing shoe 30 can move away from the lower surface 110 of the sole 10, thereby creating a gap 101 between the stabilizing shoe 30 and the lower surface 110 of the walking shoe sole 10 as the stabilizing shoe 30 moves away from the sole surface 110 via the screw 360.

[0125] Usage Example The inner stabilizing shoe 30-I and the outer stabilizing shoe 30-E are selected based on the postural defect to be corrected. For example, the inner stabilizing shoe 30-I can be thicker than the outer stabilizing shoe 30-E to correct pronation, or conversely, the inner stabilizing shoe 30-I can be thinner than the outer stabilizing shoe 30-E to correct supination. The thickness of the inner stabilizing shoe 30-I is selected based on the postural correction to be performed: the larger the defect, the thicker one of the stabilizing shoes 10.

[0126] In the presence of protective layer 317, first remove the protective layer 317 (e.g. Figure 9 exemplified).

[0127] Then, as Figures 10 to 12 As illustrated, the inner stabilizing compensation overshoe 30-I is mounted by attaching the attachment members (edge ​​312 and the stabilizing portion of the compensation portion are fitted onto the inner receiving surface 111-I).

[0128] The external stabilizing compensation shoe 30-E is installed by assembling the attachment member of the compensation part onto the external receiving surface 111-E.

[0129] exist Figure 16 In the example, it depicts Figures 13 to 15 Regarding the use of the stabilizing compensation boots 30, for clarity, only the attachment members 330 of the inner stabilizing compensation boot 30-I and the outer stabilizing compensation boot 30-E are visible. In other words, the compensation portion 310 and the stabilizing portion 320 are not shown.

[0130] Same reference Figure 16 In step “01”, the attachment members 330 of the internal stabilizing compensation overcoat 30-I and the external stabilizing compensation overcoat 30-E approach the rectangular port 124 of each cavity 122. In step “02”, the left portion 331 and the right portion 332 of each attachment member 330 are compressed at the slot 333 such that the arrowhead of each attachment member 330 is narrow enough to pass through the rectangular hole 124 of each cavity 122 before being released (step “03”), thereby allowing each attachment member 330 to be clamped into the housing 126. Then, in step “04”, a locking lever 400 is placed in the arrow of the attachment member 330. The locking lever has an H-shaped cross-section and includes two semi-cylinders 410 connected end-to-end by the wall 420, such that the two semi-cylinders slide into the visible material 334 to prevent the left portion 331 and the right portion 332 of each attachment member 330 from disengaging, thereby keeping the attachment member 330 clamped and locked in the compartment 126 (step “05”). Then, in step “06”, the trapdoor 500, which forms part of the tread, is folded down to close the housing 126.

[0131] Figure 17 A hatch 500 with an integrated locking lever 400 is shown, for example, made of the same material, wherein steps “04”, “05” and “06” are combined.

[0132] Therefore, the present invention enables the correction of one or more postural defects of a shoe wearer in a simple, quick, and effective manner by adding one or more stabilizing compensating overshoes 30 of a specific thickness according to the said postural defects. Specifically, the compensating portion enables the compensation of postural defects while providing ankle and midfoot stability according to its thickness, while the stabilizing portion enables the increase of ankle and midfoot stability of the wearer, especially lateral stability, and increases the adhesion strength of the stabilizing compensating overshoe 30 to the walking sole 10.
