Definitions
- the invention relates to footwear with unstable sole structure for restoring and/or maintaining statically optimal body posture and healthy walking and running dynamics, for child and adult users, comprising an upper and a sole structure designed to conform to the physiology of normal rolling gait, where the sole structure is attached to the upper, and where the sole structure has a wearing layer adapted for contacting the ground, a bottom layer attached to the wearing layer, an upper layer attached to the bottom layer, and a stiffener plate arranged such that it contacts the upper layer.
- Ergonomically optimal gait can be achieved only by walking barefoot on uneven ground. It has lon ⁇ / been recognised that optimal (barefoot) gait can be approximated by wearing footwear simulating unstable, uneven terrain. Wearing such footwear causes orientation sensor muscles (deep muscles) to become tensioned, which is indispensable for relieving joints and maintaining physiological body posture.
- the document with publication no. WO 01/15560 discloses footwear for dynamic rolling-walking action.
- the footwear has an upper for supporting the user's foot, to which is attached a sole structure adapted for producing the feeling of walking - - barefoot.
- the sole structure has a middle and a bottom layer.
- the middle layer is made of a relatively hard resilient material, while the bottom layer is made of softer resilient material.
- the bottom layer has arcuate segments producing an overall shape suitable for rolling gait.
- a shortcoming of the solution is that it fails to simulate walking on natural terrain adequately because of the pivot axis formed between the harder and the softer layer.
- the user has to maintain balance and ergonomically optimal body posture by continuous conscious effort ("aware walking").
- Patent description EP 0 999 764 describes a shoe designed for enabling rolling gait.
- the sole structure attached to the shoe upper comprises a sole body and a covering (a wearing layer).
- a pivot axis is disposed in the wearing layer in the metatarsal area, about which the forward and backward portions may pivot.
- a recess is formed between the sole body and the wearing layer, wherein a soft, resilient load distribution element is inserted.
- the shoe according to the invention is capable of providing natural rolling action of the foot during walking, with uniform load distribution.
- the disadvantage of the invention is that due to the fixed nature of the applied pivot axis it is only partially suitable for simulating a natural tread surface and thus for activating muscles in a near-natural way.
- a further disadvantage is that wearing the inventive shoe 'requires both training and constant attention on the part of the user. In case the wearer suffers from serious fallen arches s/he has to focus constantly on preventing ankle pronation (that could cause further impairment) while walking in the inventive shoes. If, such as in the case of small children, it is impossible to train the user for "aware walking", wearing the inventive shoes may cause further impairment. Consequently, child users or people with more serious health problems cannot use the inventive shoes without medical supervision.
- the aim of our invention is to provide footwear for simulating unstable ground surface without requiring "walking awareness" from the user.
- the invention is primarily targeted for providing footwear for children whose muscles and joints have not yet been damaged and therefore are optimal subjects for prevention.
- a further aim of the invention is to provided a sole structure wherein the side surfaces of the layers, particularly the side surfaces of the more resilient layers are protected against mechanical impact.
- a still further aim is to provide a cheaper -and lighter product through simplifying the manufacturing process of the sole structure.
- the inventive objective is accomplished by providing footwear described in the introductory paragraph of the present specification, wherein a bottom layer covering - - the tread surface is attached to the wearing layer such that the wearing layer extends at least over the side surface of the bottom layer, and an upper layer covering the tread surface is attached to the bottom layer, where the upper layer comprises a support projection adapted for preventing ankle pronation and dimensioned to at least match in size the print of the arch of the foot, with the material of the bottom layer being more resilient tjran that of the upper layer, and with the stiffener plate configured to conform to the physiology of rolling gait and to arranged for contacting the upper layer being also arranged such that it covers the tread surface and has a cross-sectional size decreasing towards the toes.
- Prior art solutions for health-preserving or health-restoring footwear have sole structures designed to enable rolling gait.
- Sole structures enabling rolling gait have a curved tread surface instead of a rigid and substantially flat sole, with areas under the toes and the heel being slightly elevated from the ground. The degree of elevation is chosen such that during normal walking the sole portion under the talus is the first to touch the ground, and the portion under the toes leaves the ground last after a continuous rolling movement. This conforms to the physiology of walking barefoot.
- a sole structure configured conforming to the physiology of rolling gait is disclosed for instance in document EP 0 999 764. Because such a sole structure configured conforming to the'physiology of rolling gait is included in the prior art it will not be described in detail in the present document.
- Such a sole structure may be produced by configuring the stiffener plate to conform to the physiology of rolling gait, with the other sole elements being glued to each another and to the stiffener plate.
- the footwear according to the invention has a sole structure and an upper attached to the sole structure.
- the upper may be made of materials conventionally applied in the shoemaking industry such as leather, imitation leather, textile, or plastic.
- the upper may have the conventional configuration of a shoe, sports shoe, boot, or even sandal.
- the footwear may comprise an inner lining, with the material and configuration of thereof being identical to solutions known in the art.
- the sole structure of the footwear according to the invention is assembled from a wearing layer, a bottom layer attached to the wearing layer, an upper layer covering the bottom layer, arfd a stiffener plate contacting the upper layer.
- the role of the wearing layer is to protect the underside of the sole structure from premature wear.
- the wearing layer according to the invention extends at least over the side - - surfaces of the bottom layer. Apart from providing protection against wear and tear for the surface contacting the ground, such a laterally protruding configuration of the wearing layer is capable of protecting the side surfaces of the softer, more resilient sole elements against mechanical damage. Such a configuration has the same effect as the configuration wherein the wearing layer completely surrounds the entire side surface of the sole structure, but is significantly lighter and is aesthetically more pleasing. According to a preferred embodiment of the invention the wearing layer completely covers the front portion of the sole structure, effectively protecting the front of the shoe from damage and wear and tear. In a preferred embodiment the wearing layer is made of resilient plastic or rubber providing good grip.
- the / bottom layer is arranged substantially perpendicularly to the wearing layer and to the tread surface, and is connected stepwise to the wearing layer.
- substantially perpendicular refers to a deviation from perpendicular by less than 5°.
- the side surface of the bottom layer is arranged at an acute angle with respect to the wearing layer and the tread surface, with the side surface of the bottom layer being connected flush to the side surface of the wearing layer.
- the bottom layer of the sole structure is attached to the wearing layer in a permanent manner, by glueing or welding.
- the bottom layer covers the entire tread surface, meaning that it extends from the rearmost point of the ankle to the tip of the toes and has a width conforming to that of the sole of the foot.
- the bottom layer comprises through- openings that are included to control the deformation of the bottom layer.
- the soft, resilient bottom layer creates the feeling of walking barefoot on uneven ground, thereby stimulating muscle activity.
- feeling the uneven ground surface which is needed to adapt to the continuously changing conditions provoked by the unstable sole structure, causes muscles to be tightened by reflex, which in turn relieves joints from load and helps maintain physiological body posture.
- Healthy walking or running dynamics is important not only for preventing joint or muscle ailments but has - - beneficial influence on the operation of other organs of the body.
- the prolonged activity of deep muscles, brought about by the unstable sole structure enhances circulation and cell and tissue metabolism.
- an upper layer covering the tread surface is attached to the bottom layer.
- the bottom layer may be attached to the bottom layer by means of welding, glueing, or the like.
- the upper layer is made from thermoplastic plastic.
- the term "tread surface” is used to refer to that surface of the sole structure on which the foot is supported.
- the tread surface can be defined as a plane figure bounded by curved lines, extending from the rearmost extremity of the ankle to the tip of the toes, having its largest width at the area where the bones of ball of the foot touch it.
- the foot is supported on the tread surface at the areas where the talus and the bones of the ball of the foot touch it, at the so-called anatomical support distance.
- the soft soles applied in conventional footwear with unstable sole structure may cause ankle pronation which can only be compensated by "aware walking", that is, by intentionally tilting the ankle ⁇ outward.
- a harder, relatively less resilient upper layer is attached to the bottom layer.
- the upper layer comprises a support projection at least in the area under the arch of the foot.
- the support projection is adapted for preventing ankle pronation and thereby removes the requirement of mindful use.
- the addition of a relatively rigid support projection to the sole structure makes it unnecessary to "learn to walk again" in the inventive footwear with unstable sole structure and to focus constantly on keeping balance. Also, the support projection opens up the possibility of using the inventive footwear for small children who do not yet understand instructions.
- the support projection provides flexible support for the ankle joint while the muscle stimulus for keeping physiological body posture is also maintained.
- the support projection can fulfill its role if it at least matches in size the print of the arch of the foot.
- print of the arch of the foot we mean the area where the surface of the sole of the foot does not touch the tread surface while the foot is supported (is resting) thereon.
- the largest length of the support projection equals at least the anatomic support point distance of the tread surface, that is, the distance between support points on the thread surface of the calcaneus and the bones of the ball of the foot, and the largest width of the support projection extends at least from the medial edge of the sole structure to the midline thereof.
- the thickness of the support projection is chosen such that it can provide flexible support for the ankle.
- the bottom layer should be thick enough to provide an "unstable environment" for the foot but should not be too thick in order not to lose the ankle- supporting effect.
- the largest thickness of the support projection should be preferably 60-80% of the largest thickness of the bottom layer. In a preferred embodiment of the invention the largest thickness of the support projection is three-fourths of the largest thickness of the bottom layej/
- the support projection is preferably made of the same material as the upper layer.
- the upper layer and the support projection form an integral element, but configurations where the upper layer and the support projection are implemented as separate elements (made even of different material) secured permanently together, for instance by glueing, also fall into the scope of the invention.
- the support projection is connected with a smooth transition to the upper layer at its end near the toes. Supporting the calcaneus by a conventional rigid sole makes walking an extremely painful experience for patients suffering from joint ailments, especially from arthritis.
- the inventive sole structure comprises a support projection that is terminated in a cutoff at its end near the heel such that it does not cover the support point of the calcaneus on the thread surface.
- the cutoff may be bounded by plane or curved surfaces.
- the cutoff surface is bounded by a plane that is set at an angle of 18-30° with respect to the midline of the sole structure.
- the angle between the bounding plane of the cutoff and the midline of the sole structure is 21 °.
- a further correction of ankle pronation is provided by arranging the surfaces of the wearing layer adapted for contacting the ground and the bottom layer in an elevated manner.
- the wearing layer is arranged at an acute angle, preferably at 83-
- a stiffener plate is in contact with the upper layer.
- the stiffener plate is made of a hard plastic material, such as PVC, or from a fibreglass reinforced plastic sheet, and has an arcuate surface conforming to the physiology of rolling gait.
- the stiffener plate is arranged such that it covers the tread surface and has a cross-sectional size decreasing towards the toes.
- Such a configuration of the stiffener plate provides uniform load distribution and load transfer to the sole structure without hampering the instability thereof.
- the stiffener plate and the upper layer are glued or welded together.
- a cover plate, applied in order to make adhesive bonding easier, and/or a support plate adapted for receiving the contacting edge of the upper and comprising cutouts, may also be attached to the stiffener plate portion connecting to the upper layer.
- An arrangement of the sole structure where the side surface of the bottom layer has a concave shape as seen from the front and the rear of the sole structure is also the object of the present invention.
- the side surface is curved.
- Arrangements wherein the side surface of the bottom layer is bounded by planes are also included in the scope of the invention.
- the side surface of the bottom layer may be curved in a concave fashion in its entirety, but the substantially concave configuration of the side surface is also included in the scope of the invention.
- substantially concave configuration of the side surface involves such arrangements wherein the side surface of the bottom layer is in specific cases broken by openings or has protrusions.
- the front and rear surfaces of the sole structure may be arranged without having concave side surfaces, particularly in case the portions of the wearing layer that extend as far as the edges of the tread surface are elevated off the ground.
- the cross section of the concave surface has a circular arcuate boundary line.
- the cross section of the concave/Surface is bounded by straight lines.
- the concave configuration of the side surface serves for the protection of the bottom layer, which is made of a more resilient material.
- the concave surface is dimensioned such that in case the sole surface is put under higher loads, for instance because the user steps on a stone or sharp-edged object, the edges of the wearing layer and the upper layer come into contact, surrounding the material of the bottom layer. In this position the soft, resilient material of the bottom layer is protected against tear and rubbing.
- Such a configuration of the sole structure significantly increases shoe life.

- the stiffener plate 6 has a non-constant cross-sectional size that decreases towards the toes.
- the upper layer 5, made of polyurethane, is dimensioned to cover the entire tread surface 8. As it is shown in Fig. 6, the upper layer 5 comprises a downwards extending support projection 9 that at least matches in size the print of the arch of the foot.
- the support projection 9 is connected to the upper layer 5 along a plane, in which plane the cross-sectional shape of the support projection is a plane figure having longer sides touching, respectively, the medial edge of the sole structure 11 and the midline 10 thereof; a first shorter side substantially perpendicular to the midline 10, and a second shorter side terminating in a cutoff 12.
- the line of the cutoff 12 is set at an angle ⁇ with respect to the midline 10, the cutoff being located anterior to the support point of the calcaneus.
- the value of the angle ⁇ is 21°.
- the upper layer 5 and support projection 9 provide flexible support to the foot while walking, with the heel being supported by the more resilient, softer bottom layer 4.
- the upper layer 5 and the bottom layer 4 are glued together.
- the undersurface 13 of the bottom layer 4, covering the entire tread surface 8, is glued to the wearing layer 3.
- the bottom layer 4 is made of a higher-resilience polyurethane compared to the upper layer 5, which provides an unstable state for the foot, successfully simulating barefoot walking.
- openings 7 are disposed in the bottom layer 4. The openings 7 are included on the one hand for decreasing the weight of the sole structure 1 and on the other hand for providing a possibility to modify or adjust the resilience of the bottom layer 4.
- the sole structure 1 is implemented such that its end portions towards the toes and the heel are elevated to a certain extent (in a manner known from prior art) conforming to the physiology of rolling gait.
- the bottom layer 4 is bounded by a front surface 20 and a rear surface 21, while side surfaces 14, 15 bound both the bottom layer 4 and upper layer 5.
