Definitions
- the disclosure relates to a hallux valgus sandal for the prevention and treatment of malpositions in the metatarsal and forefoot region, particularly the malpositions of the big toe referred to as hallux valgus.
- Malpositions in the metatarsal and forefoot region have a multitude of causes.
- malformations are inborn or hereditary; on the other hand, such malpositions are brought about by wearing incorrect footwear or the flattening of the longitudinal and transverse arch as a result of instability in the metatarsal region, particularly due to an instability of the connective tissue.
- the flattening of the transverse arch which is also referred to as splayfoot, the individual metatarsal and toe bones are fanned out radially.
- the metatarsal bone of the first ray i.e., the inner or medial metatarsal bone is abducted inward.
- the tendons of the big toe which, unlike the other toes, has an independent tendon apparatus, no longer run centrally over the first metatarsophalangeal joint but, due to their predefined length, laterally outside of it.
- the big toe is thus pulled into an oblique, outwardly oriented position.
- the formation of hallux valgus is also amplified by the subsidence of the longitudinal arch, because this predominantly medial subsidence results anatomically in a rotation of the metatarsus and forefoot outward when seen from above.
- a reference system is used in the description that is centered on the midline of the body to indicate position and direction. Accordingly, “interior” or “lying on the inside” or “medial” always refer to the midline and opposite the respective other foot. Therefore, “in the medial direction” also means in the direction of the respective other foot. “Exterior” or “lateral” refer to the side facing away from the midline of the body, so that the lateral direction points away from the midline and hence from the respective other foot.
- a metatarsal bone and the associated toe bones arranged anterior thereto are also referred to as “rays.”
- the interior metatarsal bone and the interior toe bones arranged anterior thereto are regarded as the first ray.
- the individual rays are numbered serially and increase in the lateral direction, so that the exterior metatarsal bone and the associated toe bones arranged anterior thereto form the fifth ray.
- a sandal for the correction and/or prevention of hallux valgus diseases are known from the prior art.
- a sandal is known from German utility model DE 20 2008 008 106 that is preferably embodied as a flip-flop sandal.
- the flip-flop sandal has a shoe sole as well as a big toe receiving compartment for discretely receiving the big toe separately from the other toes.
- the known sandal comprises a metatarsal bandage for supporting the metatarsus that has lateral segments supporting the sole of the foot that are pulled inward by the side flanks of the shoe upper toward the mid-sole.
- the metatarsal bandage is centered via a centering device on the shoe sole.
- the hallux valgus sandal comprises a sole element with an outsole and a footbed.
- the hallux valgus sandal further comprises a big-toe support for laterally supporting the big toe.
- a metatarsal belt circularly surrounds the sandal wearer's metatarsal bones in interaction with the sole element. The length of the metatarsal belt can be adjusted.
- a pressure cushion is arranged such that, when the metatarsal belt is applied over the pressure cushion, a laterally directed force can be exerted on the inner metatarsal bone.
- the pressure cushion is particularly arranged on the interior of the metatarsal belt in the medial region of the sandal. As a result, the pressure cushion is located between the metatarsal belt and the metatarsal bone of the first ray when the sandal is worn.
- the sandal according to the disclosure is subdivided substantially into three regions in the longitudinal direction.
- the division into regions is based on the foot of the wearer of the sandal. However, in order to provide an approximation of the regions, only average values for the respective length of the region based on a standard foot can be used for the respective foot length and shoe size.
- the tarsal bones which define the ankle or hindfoot region of the sandal and of the sole element, are located in the rear region. Starting in the heel region, the ankle region includes the heel bone followed by the anklebone laterally slightly forward. The cuboid bone and the navicular bone are located in front of that in the direction of the toes.
- the metatarsal bones also referred to as the ossa metatarsalia, are adjacent to the anklebones in the longitudinal direction in front of those and define the midfoot region or metatarsus.
- the medial metatarsal bones tend to be pushed somewhat forward toward the tip of the foot in comparison to the lateral metatarsal bones. As a result, the boundaries of the metatarsal region are shifted from the inside of the foot to the outside of the foot rearward in the longitudinal direction of the foot.
- the toe or forefoot region which is defined by the two toe bones of the big toe and the three respective toe bones of the second, third, fourth and small toe, is arranged in front of the metatarsal region. These three regions each correspond approximately to a third of the overall foot length.
- the pressure cushion has an effective length that is aligned substantially in the longitudinal direction of the foot.
- an active surface of the pressure cushion is brought into contact with the foot via this effective length.
- the length of the metatarsal belt is changed or shortened for the application of the pressure cushion.
- the length is shortened until the shoe, particularly the metatarsal belt and the footbed, rests substantially against the metatarsus, surrounds it and the desired corrective force is achieved.
- the pressure cushion and/or the metatarsal belt can particularly deform elastically depending on the material.
- the effective length of the pressure cushion preferably corresponds to the metatarsal region of the sandal, so that the pressure cushion rests against the metatarsal bone over the entire length of the metatarsal bone.
- a corrective force is applied in the lateral direction to the metatarsal bone over its entire length.
- the corrective force is not applied directly to bones, particularly to the bones of the first metatarsophalangeal joint, but rather is introduced indirectly via the soft tissues of the first metatarsal bone. This prevents pressure-related discomforts and damage to tissues.
- the corrective force is thus applied in the anterior region of the pressure cushion, particularly behind the first metatarsophalangeal joint medially onto the soft tissue of the metatarsal bone and extends rearward over the entire length of the metatarsal bone.
- the width of the metatarsal belt on its interior preferably also extends over the effective length of the pressure cushion.
- the pressure cushion is a three-dimensional element that is preferably arranged between the metatarsal belt and the foot of the wearer of the sandal.
- the thickness of the pressure cushion i.e., its extension from the metatarsal belt in the direction of the foot, can vary depending on the application, treatment or the like.
- the pressure cushion can be attached to the metatarsal belt and/or the sole element so that its position and orientation are clearly defined. Through the structuring of the three-dimensional shape of the pressure cushion, the introduction of force and distribution of pressure on the medial metatarsal bone can be set and adjusted.
- the pressure cushion is preferably integrated in flowing shapes into the metatarsal belt without producing a sharp edge.
- the pressure cushion has a greater thickness in the front region than in the rear region.
- Its shape can be wedge-shaped, convex or the like.
- the pressure cushion can be convex and thus be adapted to the foot arch. Abrupt changes in shape and resulting jumps in pressure are to be avoided. Accordingly, the various regions of the pressure cushion should form a contour with flowing transitions so that the changes in compressive force occur continuously, especially at the ends of the pressure cushion.
- the corrective force to be applied to the metatarsal bone can be adjusted in a targeted manner in its amount and/or direction. The treatment of hallux valgus ailments is thus improved.
- the width of the metatarsal belt preferably decreases from the inside toward the outside.
- the metatarsal belt thus has its maximum width in the region of the pressure cushion. This improves the introduction of pressure into the pressure cushion.
- the metatarsal belt Toward the outside, the metatarsal belt becomes narrower. It can also transition into a raised sole edge of the sandal. A commensurately raised sole edge can also be embodied in the region of the pressure cushion on the inner side of the sandal.
- the sandal has a trapezoidal or triangular receptacle in the metatarsal belt.
- the receptacle preferably has its greatest dimensions on the inside adjacent to the pressure cushion and becomes narrower toward the outside. Sharp edges must be avoided in the metatarsal belt and receptacle in order to reduce load peaks that are brought about by forces upon application of the metatarsal belt.
- the metatarsal region runs from the inside to the outside obliquely rearward.
- the middle of the metatarsal belt runs substantially parallel to the boundaries of the metatarsal region. Accordingly, the middle also runs rearward from the inside of the foot to the outside of the foot.
- the midpoint between the front and rear end of the belt is regarded here as being the middle of the metatarsal belt on which the middle connecting points of the metatarsal belt are located, so that the middle corresponds approximately to the gravity center line in the longitudinal direction of the metatarsal belt.
- the length of the metatarsal belt can preferably be changed by means of a hook-and-pile fastener.
- a hook-and-pile fastener By shortening the length of the metatarsal belt, the metatarsal belt is tensioned, thus introducing a tensile force in the metatarsal belt in the applied state of the sandal. This corrective force is applied via the metatarsal belt and the pressure cushion in targeted manner to the metatarsal bone of the first ray.
- tensioning means such as elastic elements or traction belts with an appropriate closure such as a clasp, for example, can be used.
- the hook-and-pile fastener is arranged on the outside of the sandal or of the metatarsal belt.
- a first end of a hook-and-pile strap is worked into the sole element.
- Another element of the hook-and-pile fastener a receptacle for the hook-and-pile strap, is arranged on the outside of the sandal, particularly on a raised sole edge.
- the free, second end of the hook-and-pile strap can be fastened in various positions on the receptacle, thus enabling a loop of variable length to be formed above it and rendering the length of the metatarsal belt adjustable.
- the metatarsal belt is embodied as a medial and a lateral metatarsal belt element, and the length is adjusted via the amount of overlapping.
- the two elements can be connected to each other with variable overlapping in various positions by means of snap fasteners or a hook-and-pile fastener.
- the big-toe support is embodied as a big-toe loop.
- the big-toe loop surrounds the big toe in the applied state of the sandal in an at least partially circular manner.
- the big-toe loop is U-shaped and connected to the sole element in two places.
- the big-toe support can preferably be adjusted, particularly in relation to its position and/or length. As a result, the supporting effect on the big toe is adjusted.
- the length can be adjusted, for example, by means of a hook-and-pile fastener.
- Different designs can be embodied analogously to the adjusting mechanism of the metatarsal belt.
- the big-toe support can also be embodied as a land against which the big toe rests.
- the footbed of the hallux valgus sandal is preferably embodied as an orthopedic footbed.
- An orthopedic footbed has, in particular, a longitudinal and/or transverse arch as well as receptacles or depressions for the toes.
- the footbed can also comprise one or more pelottes.
- a pelotte is generally a raised area of the footbed for medical purposes. More preferably, at least one pelotte is a proprioceptive pelotte and embodied according to Golgi's teaching, so that the pelotte exerts pressure on the foot such that it serves to regulate the muscle tone.
- the muscles are to be influenced such that a treatment of the hallux valgus is supported.
- the sole element has on its underside, i.e., in the region of the outsole, rolling slits transverse to the sole.
- the rolling slits are frequently arranged such that they support a natural rolling motion.
- the slits are arranged beneath the natural rolling axis of the toes.
- the rolling slits preferably run parallel to the natural rolling axis.
- the hallux valgus sandal according to the disclosure can be manufactured from different known materials that are common in the prior art in the manufacture of sandals, such as plastic, cork, leather, and the like.
- the outsole, big-toe support and parts of the metatarsal belt are embodied integrally of plastic.
- the one-piece design can be achieved, for example, through baking of plastic granulate or injection molding or foaming of plastic.
- a material similar to that of Crocs sandals can be used.
- Such a material has a certain inherent elasticity.
- all of the parts of the metatarsal belt with the exception of the adjusting mechanism, e.g., the hook-and-pile fastener are manufactured integrally from plastic.
- the adjusting mechanism can be embodied as an insert and is connected firmly to the plastic during the manufacturing process.
- the footbed and/or the pressure cushion can be embodied as separate parts and are therefore exchangeable.
- the footbed is embodied separately. The footbed is inserted into a receptacle in the outsole and held frictionally in its position. The footbed can thus be adapted to the wearer and, moreover, it can be manufactured from a different material or from a different material mixture than the outsole.
- the sole is slitted from the front end in the region between the first and second toes, so that the big-toe support or the big-toe loop can be embodied integrally with the outsole and guided through the footbed.
- This offers advantages to the effect that the elements can be adapted to the individual shape and to the needs of the wearer of the sandal. For instance, the strength of the corrective force can thus be adapted to the severity of the hallux valgus malposition by the size and shape of the pressure cushion. Furthermore, individual peculiarities of the foot can be taken into account by a commensurate footbed.
- the pressure cushion and/or the footbed is embodied integrally with the outsole, the big-toe support and parts of the metatarsal belt.
- additional parts of the sandal can be worked in during the manufacturing process, for example as inserts. An effective, robust and cost-effective sandal for the treatment of hallux valgus malpositions can thus be manufactured.
- the prevention and/or treatment of hallux valgus malpositions is improved.
- the treatment is administered according to the principle of “from back to front.” What is meant by this is that a treatment of the malposition does not begin merely in the toe region, but rather in the metatarsus, that is, “from the back” and continues “forward” into the toe region.
- the pressure cushion By virtue of the pressure cushion, the corrective force on the metatarsal bone can be adjusted in a targeted and gentle manner.
- the introduction of the corrective force into the respective foot can be further improved.
- the adjustment of the corrective force is particularly achieved by changing the length of the metatarsal belt.
- a tensile force is built up via the metatarsal belt that is transferred via the pressure cushion in a targeted manner, i.e., defined in strength and direction, to the metatarsal bone.
- This corrective force acts against the big-toe support and has the effect that the big toe does not drift with the metatarsal bone in the lateral direction but rather is straightened along the axis of the first ray.
- This treatment counteracts the spreading of the metatarsal bone, and a medial supportive force is applied to the big toe via the big-toe support. This results in effective treatment and prevention of hallux valgus disorders.

- FIG. 4 a front view of a sandal according to the disclosure
- FIG. 5 a view from below of the sandal according to the disclosure.
- FIG. 6 a three-dimensional representation of a sandal according to the disclosure.
- FIG. 1 shows a hallux valgus sandal 1 according to the disclosure.
- the sandal 1 comprises a sole element 10 with an outsole 12 (cf. FIG. 6 ) and a footbed 14 .
- the sandal 1 and the footbed 14 are subdivided into substantially three regions, namely an ankle region 52 , a metatarsal region 54 and a toe region 56 , which correspond to the regions of the human foot.
- FIG. 2 shows how a foot or foot skeleton 50 is received by the sandal 1 when the sandal 1 is worn.
- the anklebones 52 a are arranged in the rear region of the foot skeleton 50 (cf. FIG. 3 ).
- Metatarsal bones 54 a are arranged in the longitudinal direction in front of those and, in turn, the toe bones 56 a are arranged in front of those.
- the footbed 14 or the sandal 1 also has these three regions 52 , 54 , 56 that are defined by the corresponding bones.
- the regions each correspond to approximately a third of the length of the entire foot, although the respective absolute length is also based on the shoe size and length of the foot. However, deviations from this can arise as a result of the individual structures in the foot of the respective wearer.
- the sandal 1 also has a metatarsal belt 20 .
- the metatarsal belt 20 is arranged substantially in the metatarsal region 54 of the sandal 1 .
- the metatarsal belt 20 is embodied integrally with the sole element 10 on the inside of the sandal. Laterally, the metatarsal belt 20 has a hook-and-pile strap 22 .
- the hook-and-pile strap 22 is embedded in the sole element 10 medially to the sole outer edge and leads out of it. When the sandal is being worn, the hook-and-pile fastener on the sole element 10 is located beneath the lateral region of the metatarsus.
- the hook-and-pile strap is guided through an opening as a redirection 26 in the metatarsal belt 20 and can be fastened via a hook-and-pile strap receptacle 24 on the outside of the sole element of the sandal 1 .
- a loop is thus formed by the hook-and-pile strap 22 by means of which the length of the metatarsal belt 20 can be altered in a flexibly adjustable manner.
- the metatarsal belt 20 is arranged in the metatarsal region of the sandal 1 and, when the sandal 1 is being worn, surrounds the foot circularly in the metatarsal region 54 in conjunction with the sole element 10 and the footbed 14 .
- the metatarsal bones 54 a can thus be tensioned together by reducing the length of the metatarsal belt 20 .
- the width of the metatarsal belt 20 corresponds at the inside of the sandal 1 to about the length of the metatarsal region 54 of the sandal 1 .
- the width of the metatarsal belt 20 decreases in the lateral direction.
- the metatarsal belt 20 is shifted rearward at its lateral end in the longitudinal direction of the foot in relation to its medial end.
- the metatarsal belt 20 thus runs substantially parallel to the metatarsal region 54 of the foot and of the sandal 1 .
- the metatarsal belt 20 is embodied with a receptacle 28 having a trapezoidal shape. The force effect is thus optimized with minimal weight and minimal material cost.
- a pressure cushion 30 is arranged on the inside of the sandal 1 in the region of the metatarsal belt 20 .
- the pressure cushion 30 is embodied integrally with the inside of the metatarsal belt 20 and of the footbed 14 .
- the pressure cushion 30 rests against the inside of the foot over the effective length L.
- the pressure cushion 30 is substantially wedge-shaped and has a greater thickness in the lateral direction in the front region than in the rear region.
- the pressure cushion 30 is located between the metatarsal belt 20 and the inner metatarsal bone 54 a , i.e., the metatarsal bone 54 a of the first ray.
- a corrective force Fk is exerted via the pressure cushion 30 on the metatarsal bone 54 a of the first ray.
- the corrective force Fk acts substantially in the lateral direction.
- the spreading i.e., the malpositioning of the anklebone 52 a , particularly of the metatarsal bone 54 a of the first ray and hence the hallux valgus as well, is counteracted.
- the corrective force Fk is higher in the front region of the metatarsus 54 than in the rear region.
- the front force attack point is placed in the region of the soft tissues behind the first metatarsophalangeal joint.
- the pressure cushion 30 or the effective length L is embodied substantially over the entire length of the metatarsal region 54 of the sandal 1 and of the metatarsal bone 54 a of the first ray.
- the big toe is supported laterally by a big-toe support 40 that is embodied as a big-toe loop 42 .
- the loop 42 is substantially semicircular, as shown in FIG. 4 , and surrounds the big toe circularly in conjunction with the footbed 14 .
- the big-toe loop 42 thus counteracts a lateral movement of the big toe, which is particularly also achieved through application of a lateral corrective force Fk on the metatarsal bone 54 a of the first ray via the pressure cushion 30 .
- the corrective force Fk can thus be applied to the metatarsal bone 54 a of the first ray and an opposing force Fw can be applied to the toe bones 56 a of the first ray in order to counteract and correct a hallux valgus malposition.
- the corrective force Fk can be adjusted by the wearer themselves via the length of the metatarsal belt 20 or via the length of the hook-and-pile strap 22 .
- the footbed 14 is anatomically shaped and has several palottes 16 , i.e., raised areas in the region of the metatarsus and hindfoot.
- a retrocapital and a hallux pelotte 16 a , 16 b are arranged here according to Golgi's teaching in order to influence the plexus for regulating muscle tone.
- the retrocapital pelotte 16 a is arranged over the entire width in the metatarsal region and exerts a pressure on the tendons of the toes running beneath the foot skeleton. The pressure on the tendons leads to a relaxation of the toe flexor musculature.
- a hallux pelotte 16 b which is arranged above the retrocapital pelotte, so that the raised area is raised further here from the footbed.
- the hallux pelotte 16 b exerts additional pressure on the tendon of the big toe lying beneath the skeleton.
- a valgus pelotte 16 c is arranged in the medial region of the footbed 14 in the longitudinal direction behind the hallux pelotte 16 b . Due to its position in the medial hindfoot region, the valgus pelotte 16 c has an activating effect on the longitudinal arch musculature. As a result, the longitudinal arch is raised.
- outsole 12 has rolling slits 18 on its underside in the transverse direction.
- the rolling slits 18 are shifted downward parallel to a natural rolling axis of the foot.
- the sandal 1 is made in a substantially integral manner of plastic. Only the hook-and-pile strap 22 is worked in as an insert through the firm connection of an end of the hook-and-pile strap 22 to the sole element 10 .
- the sandal 1 has a receptacle 24 for the hook-and-pile strap 22 on its underside that is also firmly connected to the sandal 1 as an insert.
- the hook-and-pile strap receptacle 24 is embodied as a felt strap with hooks and the hook-and-pile strap 22 as a fleece strap.
