Abstract

The invention relates to a shoe insole with a clasp-like functional element for enclosing the foot. The functional element according to the invention, interchangeably designated as ankle tongues, can also be used separately from the shoe insole as an insert part or can be inlaid, knitted in, or adhered onto or into a sock. The shoe insole according to the invention or the functional element according to the invention lead to pressure being applied to the foot in front of and behind the medial malleolus and lateral malleolus and muscle fascial lines running under the sole of the foot. In this way all essential fascial lines on the foot are stimulated by sensors, which can have a positive effect on the support and motor system. At the same time an improvement of the form fit between foot and shoe is achieved by the cushioning material of the ankle tongues. The foot is securely guided, muscular tension is improved and thus movement is boosted.

Shoe insole with grandchildren's tongues to surround the foot for pressive stimulation of the myofascial features on the foot

The shoe insert according to the invention with a functional element, hereinafter also referred to synonymously as grandchildren's tongues for enclosing the foot, can positively influence the foot as well as the holding and musculoskeletal system through a pressive and stimulating response to the muscle-fascia tracts running on the foot and through a simultaneous improvement in the fit of a shoe . The load capacity of the foot is improved and the movement is dynamized.

The foot is the base of the myofascial muscle chains that are required to stand, walk, or perform other movements.

The functional support of the myofascial features on the foot by the device described here for enclosing the foot with grandchildren's tongues - installed as a shoe insert - goes a significant step beyond the current state of the art and is the result of taking into account the more recent findings on myofascia and their orthopedic and biomechanical aspects Meaning.

To date, insoles have been the standard for improving the fit and in the event of malfunctions in the support and musculoskeletal system. It can be effective when worn in a shoe or sandal. In general, the foot is provided with a passive element placed under the sole of the foot, which element adapts to the actual or desired contours of the lower surface of the foot. Different types of insoles all have the same goal: to support the foot passively or actively during its loading processes and to avoid incorrect loading.

Orthopedic insoles are generally individually manufactured and can have a strong corrective effect. Ready-made insoles are not individually manufactured and take little account of the individual foot design. They generally bed that The sole of the foot or the foot or compensate for volume deficits between the interior of the shoe and the foot (deficits in fit).

All these insoles according to the current state of the art have the property that their edge does not or only slightly extends beyond the level of the sole of the foot. They do not take into account, because of their low overall height, which are present around the inner and outer ankle de semicircular trough-shaped depression and thus the topography of the foot, respectively. the prominence of the inner and outer ankle (grandchildren). In the groin construction, the contour around the inner and outer ankle, i.e. where essentially the muscle-fasciae runs, is not taken into account.

The aim of the invention was to close or fill this space and with this measure to achieve a pressive and thus stimulating effect, as the important muscle fasciae in front of and behind the inner thigh (inner ankle) and in front and behind the outer thigh (outer ankle) run superficially. Their pressive influence has effects on the holding and musculoskeletal system and the body's own stabilization processes are stimulated by activating the entire holding and musculoskeletal system.

The grandchildren's tongues to encircle the feet can be used for everyday and sporting activities, at any age and gender. Since the loading process in standing and walking is changed by a shoe compared to walking barefoot, the possible negative consequences of wearing shoes should be minimized or even compensated for by using the foot enclosure according to the invention.

The shoe insert according to the invention with grandchildren tongues for enclosing the foot is based on the sensor system of the foot. It catches the biomechanically induced changes in the contour of the foot when the shoe is under load and, through the resulting contact, addresses the sensorimotor system of the body by exerting pressure.

It consists of a sole to be inserted into a shoe with grandchildren's tongues that are as clover-shaped as possible and encompass the foot (Fig. 1), which, through a special pressure effect on special areas of the foot, the sensors of the muscle-fascia tracts, i.e. the superficial back line, the deep frontal line, address the lateral line as well as the spiral line (according to Thomas W. Myers, Anatomy Trains: Myofascial Meridians, Myofasziale Guideways for manual and movement therapists, 2015). By exercising a proprioceptive stimulus on the fascial courses, these are stimulated.

The grandchildren's tongues of the shoe insert according to the invention preferably form a cloverleaf-shaped foot enclosure in the shape of a warped, lying, X ‘(Fig. 1). The enclosure goes under the sole of the foot below the plantar fascia in front of the heel bone. The front upper leg of this 'X', the frontal -mediale grandchildren tongue, Fig. 1 (2), runs on the inside of the foot at the level of the talus head diagonally up towards the instep of the foot in front of the inner ankle up to the upper edge of a shoe, the rear upper leg of this 'X', the dorsal-medial grandchildren's tongue, Fig. 1 (3), runs behind the inner ankle towards the heel edge of the shoe; the rear upper leg of this 'X', the dorsal-lateral grandchildren's tongue, Fig. 1 (4), runs around the sole of the foot behind the contour of the outer ankle to the edge of the shaft in the area of the heel cap, the front upper leg of the 'X', the frontal lateral one Grandchild's tongue, Fig. 1 (5), runs in front of the outer ankle to the upper edge of a shoe.

The grandchildren's tongues are made of different materials. Their edges are chamfered. An advantageous embodiment provides a low to medium Shore hardness, is compressible, resilient, can be kept in a thickness of 1 to 10, preferably 5 to 8 millimeters, and is flexible. A slight longitudinal stretching of the material can be permitted.

The upper area of this lying 'X', from its intersection on the inside to the front inner frontal-medial tongue, Fig.l (2a), can be made stronger and thus exert a stronger pressure on the skin of the sole of the foot and on the area of the longitudinal arch of the foot. There the receptors of the plantar fascia and thus the “superficial back line” and the “deep frontal line ^4” are addressed.

The cloverleaf-shaped design of the grandchildren's tongues leads to the activation of the receptors in and over the fascial courses there when closing or lacing the shoe, as well as increasing stress when walking and running through contact with the skin in the area of the contour of the foot around the inner and outer ankle.

The shoe insert or the functional element with four grandchildren tongues is shown in a three-dimensional view in FIG. Fig. 3 and Fig. 4 show the shoe insert with only three or

2 grandchildren tongues to surround the foot. The functional element is preferably thinner Execution under the sole of the foot in the direction of the so-called spiral line, so that the grandchildren's tongues on the inside and outside are connected to one another. If the sole is present, this connection can be integrated into the sole or run under the sole.

FIGS. 5 (from the medial) and 6 (from the lateral) illustrate the positioning of the grandchildren's tongues of the shoe insert and the functional element according to the invention in the applied state on the foot.

The construction of the sole of the foot-encompassing shoe insert with grandchildren's tongues can be produced using customary manufacturer-specific processes. The surface structure, FIG. 1 (8), on the other hand, should, according to the invention, follow the course of the fasciae on the foot in its structure. The texture of the surface consists of soft cushioning material, which has solid or broken lines, preferably 1 to 2 millimeters in height and preferably 4 mm in width. These fan out to form a ball, taper towards the inner and outer ankle and converge there.

The texture can run in five tracks corresponding to the five-limbed foot, starting from a point behind the inner ankle and spreading outwards towards the toes, Fig. 7 (8). This texture should follow the tendon courses of the tibialis posterior muscle, the flexor hallucis longus muscle and the flexor digitorum longus muscle and thus the course of the plantar fascia. The texture can be left out in the area of the ball of the foot or kept flat and can be more prominent again at the toe-side end of the insole. The tips of the toes meet a structured surface texture.

In a similar way, the structured texture can be single-line but multi-layered starting from the outside of the foot behind the outside ankle, FIG. 1, texture profile (8). It continues under the sole of the foot to the inside of the foot at the level of the tarsus. The textures that run towards the inside of the foot then cross over the sole of the foot and become flatter towards the front.

The thickness of the shoe insert with grandchildren's tongues should preferably be 2-5 mm in the area of the ball of the foot, but can also be designed in heights of up to 15 mm for special requirements, for example for the use of the shoe insert by diabetics.

An advantageous form of manufacture for the shoe insert with grandchildren tongues for enclosing the foot is shown in FIG. It can be cast, pressed, punched or cut with upholstery. will be. The grandchildren's tongues can be folded up on the inside and outside when importing into a shoe along a predetermined bending fold Fig. 1 (7).

In a further form, the functional element with grandchildren tongues to surround the foot can also be designed as a lying, X ‘with four grandchildren tongues without a sole. In Fig. 8, this embodiment is shown highlighted. The weaker drawn sole in the background only illustrates the positioning of the insole in the shoe.

In a further form, the shoe insert with grandchildren tongues to surround the foot can also be designed as a lying 'Y' with then three grandchildren tongues without a sole, Fig the outside runs obliquely over the outer edge of the foot behind the base of the fifth metatarsal behind the contour of the outer ankle up to the upper edge of a shoe.

In a further embodiment, the shape of the shoe insert with grandchildren tongues to surround the foot can also be made in the shape of a lying 'U', FIG Outer ankle runs to the edge of the shaft and the other part of this 'U' runs around the inner arch of the foot behind the contour of the inner ankle and can be made stronger or thicker in the area of the inner arch of the foot in order to address the plantar fascia and the arch pressively. In this version, the fronto-medial grandchildren's tongue is also omitted.

Another embodiment of the shoe insert according to the invention with grandchildren tongues is the design of the shoe insert with four, three or two grandchildren tongues to surround the foot as a three-quarter or half sole.

Another possibility of applying the functional element to the foot with grandchildren's tongues for pressively influencing the myofascial traction lines in the "X", "Y" or "misshapen" design is to sew or sew the functional element into a sock or stocking to insert, stick or glue in a pocket provided for this purpose or to bring it in in any other suitable manner. When the shoe is closed or when a foot clad with such a sock is stepped into a shoe, the “X”, “Y” or “misshapen” surrounds at the desired location of the shoe through the upper material of the shoe Pressed and the fascial courses lying in and under the corresponding skin areas are stimulated by sensors.
