Definitions

  • the invention relates to a sole of rigid material, in particular wood, and shoes, sandals or boots equipped therewith.
  • a contoured sole made of wood is known from US Patent 3 305 947.
  • the heel rest is considerably lowered with respect to the ridge of the bridge leading to the hollow for the ball of the foot.
  • the ball hollow is formed by a relatively narrow depression from which the toe rest rises, which is contoured in such a way that the toes adopt a gripping position.
  • the object of the present invention is to provide a sole of the type mentioned above, avoiding the disadvantages of known arrangements and making possible.
  • the object set out above is achieved by a sole of rigid material, especially wood, whose insole is essentially adapted to the shape of the foot, wherein the toe area rises from a hollow in the ball area, the tangent essentially lies in each plane of the sole, such plane being parallel to the middle longitudinal plane, is parallel to an outsole flat portion in the ball area or to a flat outsole, touches the highest point of the sole contour in the region of the longitudinal arch and forms the chord across the shoe heel rest, the flat portion lying in the plane of the outsole heel portion,.a line connecting this highest point with the lowest point of the hollow in the ball area forms an angle oC of about 8-12° with the tangent, and the front portion of the toe area is higher than the shoe heel rest.
  • the insole flat portion is practically a front tread surface which blocks an outer roll-off movement as long as possible via the roll-off curvature and thus induces an inner roll-off movement of.the foot on the insole. Nevertheless, in the last phase of an ambulatory movement, the inner roll-off movement can pass into an outer roll-off movement performed via the roll-off curvature.
  • the inventive inclination in the region of the bridge results.in a relatively wide ball hollow, which permits an inner .roll-off movement on the ball of the foot.
  • the subsequent rise of the toe rest makes it possible on the other hand to shift the weight even more onto the heel, and on the other, the foot is-given so much support in the toe area that it cannot slip off while the heel can easily rise.
  • the advantages achievable with the invention are to be seen in particular in the facilitation of a natural walking motion in that the main weight is shifted onto the heel while the longitudinal arch carries relatively little weight in conformity with natural conditions. The advantages are thus to be seen in that even feet or legs which otherwise quickly show fatigue symptoms or aches can be exposed to stress over long periods.
  • the ball of the foot through which the inner roll-off movement is effected is secured in its ' position which can facilitate the inner roll-off movement and have a positive effect on the weight shift onto the heel. At the same time it is thereby ensured that the sole is almost permanently in contact with the foot during walking.
  • the roll-off movement is further advantageously influenced in the above-mentioned sense if a roll-off area is provided in the ball and toe area on the outsole. This roll-off area passes into the outsole flat portion.
  • the flat portion extends with its front rim to the region below the ball hollow, while the front rim of the flat portion can run approximately parallel to the groove lying perpendicular to the middle longitudinal plane and appearing in the region of the ball hollow.
  • the flat portion meets the roll-off curvature tangentially.
  • the eight is as desired shifted onto the heel which can by nature support great weights and at the same time the weight is as likewise desired removed from the longitudinal arch of the foot.
  • the outsole heel block can be temporarily equipped with detachable pieces of different thicknesses. If the intermediate piece or spacer is shaped as a shock absorber, an excellent shock-absorbing effect is produced resulting in a bouncy walk which protects the bones and-joints.
  • the back sloping heel cap prevents a shoe or sandal provided'with the inventive sole from falling off or slipping away from the foot while being worn, even if the ground slopes up, and on the other hand nevertheless ensures surefootedness in the walking motion and standing position. Thanks to the fact that the heel cap slopes back slightly over its entire height, it is at the same time ensured that.the inner roll-off movement is not hampered. Rather the heel is thereby given sufficient room when the sole of the foot performs the roll-off movement on the insole.
  • At least one instep band delimiting the opening and having at least a portion of elastic flexible material can be arranged according to the invention between the heel cap and the front cap. Thanks to its flexibility, the inventive instepband adapts itself to the foot performing the roll-off movement on the. insole, and does not block or hamper this roll-off movement.
  • the instep band shrinks to its original dimension, whereby the sole is advantageously and automatically drawn to the foot and secured to it in a fixed position, which results not only in surefootedness and support, but also in that at the same time the weight is largely taken off the toes, which can contribute to a considerable relaxation in the toe area.
  • the front cap in the region of the opening can be so wide that there is enough room for the inner roll-off movement and pressure points are sure to be avoided, so that the intervals at which fatigue symptoms appear are advantageously lengthened. The advantages achievable thereby are thus to be seen in increased safety and comfort.
  • An advantageous embodiment of the invention can consist in the instep band exhibiting ends fitted externally. This measure ensures that the instep band cannot slip down inside and obstruct the opening. Rather, it is thus ensured that the instep band always delimits a clear opening and so makes it easier to put on a shoe according to the invention.
  • Another advantageous embodiment can consist in that the instep band is provided with elastic strips-in the region of its ends and is preferably fitted with these strips at the sole. This ensures that the flexible ends are relatively long and thus relatively high elasticity and flexibility. At the same time the rigid sole used herein makes possible a simple but nevertheless reliable fastening.
  • the use of elastic strips for forming flexible sections in the instep band advantageously results.in an especially simple and therefore cost- saving manufacture.
  • the . instep band can have at least two sections joinable by a strap buckle. In this manner it is ensured that the instep band can be adjusted to any foot, providing in each case reliable support and excellent.surefootedness.
  • the front cap can advantageously have an expanding slit to ensure proper fastening on the one hand and sufficient room on the other hand.
  • the inventive sole can also be used for boot:legs fastenable with the aid of fastening means such as buckles or laces, and can be mounted onto a sliding or rolling base part. Examples of such boots are ski boots or skating boots.
  • the insole is essentially-flat in shape.
  • the boot leg enclosing the ankle is inclined forwards with respect to the flat outsole.
  • the front area of the foot which compared to the heel is relatively weak, is thus placed under relatively heavy strain, while the heel which is by nature more capable of supporting heavy weights is strained relatively little.
  • the ankle joint is -permanently bent, which virtually immobilizes the foot.
  • the region of the foot which is only intended to be strained slightly is strained virtually the whole time, which can show up in that the foot gets tired quickly, or cramped or cold.
  • the boot with the inventive sole does not have this drawback, since not only is the weight shifted to a high degree from the longitudinal arch and the ball of the foot to the heel, but the boot also permits a relatively easy walking motion when the boot leg is unfastened.
  • the leg of this boot connected to the sole forms a shoe heel cap running at least perpendicular to the plane outsole at least to the height of the heel.
  • the inventive contour of the insole together with the free movement in the heel area provided by the heel cap permits an inner roll-off movement of the foot sole on the insole, thus facilitating ambulation.
  • the toe rest which steadily rises forwards-ensures that the toes can easily press against: the - sole, whereby the ball of the foot performing the inner roll-off movement is maintained in the right position in the ball hollow, and whereby the rising of the heel is facilitated.
  • the slight inclination of the bridge and the level of the heel rest adapted thereto also have an advantageous effect on this.
  • the longitudinal arch of the foot is not only prevented-from being forced upward, but the main body weight is also shifted onto the heel. If the leg of the boot is fastened, the heel taking the main weight is conveniently accommodated in the room provided by the heel cap, which results in a comfortable, tension and cramp-free fitting of the boot.
  • the sole can be a wooden blank providing an excellent insulation against cold.
  • Such a sole can be simply prepared from an-approximately square blank.
  • the sole depicted in Figures 1 to 4 is a one-piece, rigid wooden sole which has been simply worked from a square blank, as described further on, whereby the lower surface of the blank is tangential to those points of the outsole which are in contact with the ground when a person wearing such a sole treads on ⁇ level ground and the upper surface of the blank is tangential to the insole.
  • the sole designated in its entirety as 1 is provided with a heel 2, the tread surface in the heel area 3 which comes into contact with the ground.being separated by a downward opening recess 4 from a front tread surface formed by a flat portion 5. When set down on level ground, this front tread surface likewise comes into contact with the ground.
  • the flat portion 5 lies in a plane tangential to the heel area 3, which is here depicted as being slightly curved, the plane being shown in Figure 2 by the line 6.
  • the heel area 3 can lie completely in a plane with the front flat portion 5.
  • the front tread surface passes into a convex roll-off area 7.
  • the border line 8 between the front flat portion 5 and the roll-off area 7 runs roughly perpendicular to the middle longitudinal axis and parallel to the front heel rim.
  • the rear delimitation line 9 can be slightly. slanted or curved so that at its longitudinal sides the sole is rather broader.
  • the function of the front flat portion 5 is explained in more detail below.
  • the outsole is not covered.
  • a rubber covering is provided in the region of the front flat portion 5 and the roll-off area 7 into which it passes, the lower profile of this rubber covering running virtually parallel to the depicted profile of the outsole.
  • a heel rest 10 In the region of the insole is provided in a per se known manner a heel rest 10 above the heel 2. From this heel rest 10 there runs a longitudinal arch 11 or bridge, contoured to the longitudinal arch of the foot, to a ball hollow 12 which is contoured to the ball of the foot and ends in a toe area 13, as can best be seen from Figure 2.
  • the insole is approximately contoured to the profile of the human foot, i.e. the sole 1 is provided with a gradient which rises up to the edge. This is especially apparent in the region of the heel rest 10 and the bridge and, approximately as in Figures 3 and 4, serves to form a trough in the region of the heel rest 10. In the region.
  • the heel rest 10 is contoured approximately symmetrical to the middle longitudinal plane. In the region of the bridge the inner sole edge is somewhat raised in relation to the outer sole edge, in conformity with the natural contour of the foot. This can best be seen from Figure 4.
  • the longitudinal arch 11 falls off in a slight curve down to the lower lying ball area 12 from the heel rest 10 which is approximately tangential to it, in such a manner that the longitudinal arch of the foot which is held from below is supported but not forced upwards, so that it rests under virtually no strain at all.
  • the major part of the body weight on the sole 1 is transmitted via the heel, which is intended by nature to bear heavy loads, to the heel rest-10 which, apart from its contouring in conformity with the sole of the human foot, is roughly horizontal, i.e. parallel to the plane 6, and the level of which is approximately at the height of the upper bridge region, as can be seen in Figure 2 from the tangent 15 parallel to the tread surface and constructed to the longitudinal arch 11.
  • the desired unburdening of the longitudinal arch and loading of the heel is achieved if the line 16 connecting the lowest point 27 of.the hollow in the ball area 12 to the associated highest point 28 of the longitudinal arch 11 is inclined at an angle ⁇ of 10° to the tangent 15. As tests have shown, the desired result is.however still achieved in the range between 8 and 12° to a satisfactory degree. The same essentially applies to all longitudinal sections parallel to the toes. In some cases there is.at most a slight deviation in an upward direction in the sole region contoured to the inner region of the foot. In the example which forms the basis for the figures the heel rest 10 is also slightly concave longitudinally from the upper region of the longitudinal arch 11, as can be seen from Figure 2.
  • the resulting depression (depth t) in respect to the level of the tangent 15 should, however, be smaller than the natural contour of the human heel accommodated in this region, which can have a positive effect on the desired load uptake in the heel region.
  • the depression can be dispensed with altogether with the result that the heel rest 10 lies- virtually entirely on the level of the upper region of the bridge or longitudinal arch 11.
  • the toe area 13 rises from the hollow of the ball area 12 in such a way that the result is a gentle concavity in the region of the ball area 12.
  • the bent of the toes is intended to support a body posture by which the load is borne by the heel and also to ensure that the foot maintains its position relative to the insole, in other words that it is not shifted forward, which prevents tensions in the instep area and allows correct positioning of the ball of the foot during the roll-off movement.
  • the front edge of the toe area '13 projects past the tangent 15.
  • the toe area 13 is therefore elevated to the point at which the line 16a connecting the front section of the toe area 13 and the lowest point 27 of the ball area 12 forms - an angle B in the range of 15 - 20°, preferably 17.5°,withthe tangent 15.
  • the measures described above on the one hand ensure the desired loading of the heel and unburdening of the longitudinal arch, but on the other hand they also make it possible for the sole of the foot to perform a roll-off movement on the insole.
  • This inner roll-off movement is induced by the front tread surface situated in the region under the ball area 12, the tread-surface virtually completely blocking the sole 1 from a roll-off movement via the roll-off area 7.
  • the inner roll-off movement takes place via the balls of the feet, which are accommodated in the ball area 12, the latter offering adequate roll-off clearance thanks to the fact that it is slightly convex.
  • the toe area 13 provides adequate support to hold the ball of the foot on the ball area contoured to it, on the one hand, and, on the other, to permit it to rise back with the heel.
  • the support ensured in the region of the toes means that when the wearer takes a step the sole cannot tip downwards with the heel.
  • the measures of the present invention virtually make it.possible to simulate a barefoot walking motion.
  • the front flat portion 5 by which means an.-external roll-off movement is prevented can be so dimensioned that the front delimitation lies more or less below_the lowest point 27 of the ball area 12. Even if the front flat portion 5 is made narrower as in the illustrated embodiment, however, excellent results can still be achieved. Tests have shown that the front flat portion 5 should nevertheless not be narrower than about 2 cm.
  • the sole 1 can be shaped from a blank of the type with outlines shown in Figure 2 at 17.
  • the height.of the blank is approximately equal to the greatest sole height, so that the front flat portion 5 and the heel area 3 are practically tangential to the lower surface of the blank and the front tip of the toe area stretches to the upper surface of the blank, apart from a machining allowance which is necessary in practice and not depicted in Figure 2.
  • the level of the heel rest 10 does not appreciably deviate .from the blank upper surface, it is also comparatively simple to work.
  • the sandal upon which Figure 5 is based consists of a sole also designated here by 1 of the type described above, onto which are affixed an instep/toe band 18 and a heel cap 19 externally enclosing the heel rest 10.
  • the sole 1 can additionally be provided in its upper region with a peripheral recess 20, as can be seen from Figures 3 and 4.
  • This recess takes up the securing edge of the instep/toe band 18 and the heel cap 19.
  • the instep/toe band 18 and the heel cap 19 are simply fastened to the sole 1 by pins 21.
  • pins 21 It would,however, also be possible to construct the sole 1 and the heel cap and/or the instep/toe band as one piece. Such a construction could, for example, be manufactured from a plastic blank.
  • the rear height of the heel cap 19 corresponds roughly to normal heel height, resulting on the one hand in excellent stability, and on the other serves to prevent the sandal from falling off the..foot of its wearer or the wearer's foot from slipping out...Through its entire height the rear region of the heel cap 19 is inclined back slightly, which gives the heel the necessary freedom when performing the desired inner roll-off movement. Thanks to the unburdening of the longitudinal arch of the foot, the opening in the instep/toe band 18 is subjected to only comparatively little strain. It is therefore possible to achieve full freedom from tension in the region of the opening 22 of the instep/toe band 18 by manufacturing the latter from relatively soft material. In the illustrated embodiment two lateral slits 23 are made in the region of- the opening 22 to ensure especially high flexibility of the instep/toe band 18. These slits.-can be bridged by a rubber strip not detailed here.
  • the heel 2 is formed by a heel piece 24 containing the heel area 3.
  • This heel piece can be detachable affixed to a heel block 25.
  • a notched or screw connection can simply be provided.
  • a connection can be made using wooden screws which can be screwed in from the heel area 3; the screw heads can be sunk in the heel piece 24.
  • a spacing piece 26 can be laid between the heel piece 24 and the heel block 25, this spacing piece having shock-absorbing properties, which advantageously results in a dulling of the impacts upon the heel and thus a bouncy walk and excellent protection for the bones and joints.
  • the roll-off area 7 runs approximately parallel to the surface of the ball area 12 and the toe area 13. This ensures that the sole thickness is the same in this region. It would, however, be directly possible to round off the roll-off area 7 more sharply if individual circumstances require in order to have a positive effect on the external roll-off movement taking place in the last phase of the stride.
  • the sole according to the present invention results altogether in a backward inclination between the front end section of the toe area and the heel rest.
  • the outsole of the rigid sole 1 is provided with an elastic heel piece 24, 24'. rhe hollow in the ball area is spanned by a front cap 29 which is closed to the front in the region of the toe rest.

  • the boot leg 39 is formed in the region of the heel rest 10 as heel cap 42 sloping back slightly to the height of the heel.
  • This measure provides sufficient room for the heel when the boot leg is unfastened, i.e. unbuckled. Therefore, the foot can roll off on the insole when the boot leg is unfastened, which facilitates ambulation without skis or in ski touring.
  • This inner roll-off movement is effected via the ball of the foot resting in the hollow of the ball area 12.
  • the gentle concavity of the ball area 12, the slight rise of the lon g titudinal arch 11 along the inclined connecting line 16, as well as the horizontal orientation of the heel rest 10 in the area of the upper bridge level facilitate this inner roll-off movement.

  • the instep . height of the interior can be greater than the normal toe thickness so that the toes permanently have sufficient room to move. Since the heel cap 42 is positioned at least perpendicular to the outsole 3" and is preferably sloped back slightly, there is not only sufficient room to perform an inner roll-off movement but at the same time an immobilization and inclination of the ankle joint is prevented. As soon as the buckles are closed the heel comfortably seats itself practically automatically in the room provided so ensuring that the boot fits properly. For this purpose, the clearance of the boot leg between heel and instep is expediently so dimensioned that in.the closed position it snugly encloses the foot.
  • a ski boot of the type described above advantageously ensures that the body weight mainly rests on the heel and that the longitudinal arch of the foot and the ball of the foot are largely free from strain, so that those zones -of the foot which are by nature weak are strained little, with the result that even in cases of foot, leg or joint complaints the boots can be worn for long periods. This at the same time facilitates an inner roll-off movement and thus easy ambulation without skis.
  • the invention is illustrated by means of a ski boot.
  • skating boots or roller skating boots and the like can be improved in the same manner.
  • boots according to the invention it is advantageous to facilitate the bending movement by making the upper leather at the back of and above the heel, i.e. between the heel cap and the leg of the boot, from a relatively soft material, or alternatively to provide a suitable soft insert having a surplus of material.
