Definitions

• the invention relates to a sandal consisting of a sole, a heel cap with an ankle strap encompassing the ankle and a forefoot strap encompassing the forefoot or the like.
• Known sandals of this type have a sole that extends over the entire length of the foot with a more or less high heel, the sole usually corresponding to the sole of normal shoes in terms of thickness and flexibility, but is often even thicker than the sole of normal shoes.
• the sole of conventional sandals is therefore slightly longer than the foot itself, i.e. it protrudes slightly above the heel at the back and slightly above the toes at the front, and the sole has a relatively low degree of softness.
• a real rolling movement of the sole takes place on the floor.
• the heel and ball of the foot are alternately loaded, but in this case there is no real rolling movement when walking, but rather a tilting movement of the foot on the ball of the foot.
• the inelastic, not very flexible sole of conventional shoes and sandals hinders the walking movement of the foot in such a way that the foot instead of the natural tilting movement described above over the ball, the rolling movement predetermined by the sole, which can only be bent to a limited extent, over the front midfoot area, the ball and the toe area must understand, whereby the ball can only partially fulfill its natural support function and a part of the foot load when walking is shifted to the toes and the toe joints and these are thus subjected to a naturally high stress.
• the invention is therefore based on the object of providing a sandal in which the load conditions of the foot and the course of movement when walking correspond as far as possible to the natural conditions when walking barefoot, in particular the natural tilting movement of the foot over the ball is impaired as little as possible.
• the sandal according to the invention are the longitudinally elastic design of the sole and preferably also a shortened sole length that only extends to the front under the balls.
• the sole can adapt to the change in length of the sole line of the foot during the natural walking movement and does not hinder this, and the natural movement sequence is also not impaired in the ball / toe area.
• the flat, very flexible sole protects the sole of the foot without changing the natural weight distribution of the foot.
• the sandal according to the invention is preferably used at home, during office work and, provided the weather is favorable, also when walking outdoors, so that the foot can relax.
• Figure 1 is a side view of a basic embodiment of the sandal according to the invention.
• FIG. 2 is a view of the sandal shown in FIG. 1, and
• Fig. 3 is a side view of a preferred embodiment of the sandal according to the invention.
• the side view of the sandal in FIG. 1 also shows the foot in the forefoot area.
• the sandal consists of a sole 1, a heel cap 2 fastened to the rear end area thereof with an ankle strap 2A encompassing the ankle, and a forefoot strap 3 attached to the front sole area and encompassing the forefoot.
• the sole 1 is lengthwise divided into two sections 10 and 11 at a point in the arch area, i.e. at a point between the heel area and the ball area of the foot, and in the present exemplary embodiment both sole sections 10 and 11 each consist of two layers 10A, 10B and 11A, 11B .
• the two sole sections are elastically connected to one another by a seam 12 made of elastic material, so that the sole can be elastically stretched in the longitudinal direction.
• the elastic seam 12 consists, as can be seen more clearly from the bottom view according to FIG. 2, preferably from a flat rubber band or the like side and bottom of the sole can run without
• the sole 1 does not extend over the entire length of the foot, but the front sole section 10 ends between the ball area B and the toe area ZK, so that it just barely picks up the balls of the foot, but the toes do not rest on the sole.
• the sole thickness at the front end of the front sole section 10, at least in the front part of the contact area of the ball of the foot, is thinner than at the rest of the sole, which can be achieved by making the upper layer 10A of the front sole section 10 shorter than the lower one Location is 10B.
• the heel counter 2 is made of soft material and has only a relatively small circumferential extent that it does not affect the flexibility of the sole. For this reason, the heel counter is only designed as a relatively narrow strip in the area of its connection to the sole.
• Ankle strap 2A is at least partially made of elastically stretchable material, so that it can stretch a little as needed during the walking movement of the foot and also makes it easier to put on.
• the forefoot strap 3 is designed as a relatively narrow strap with a width of about one and a half centimeters and can be adjustable in length in order, for example, to be able to accommodate swelling of the foot. What is also important is its arrangement in the course of the sandal length such that it encloses the forefoot in the ball area, that is to say that its front edge area does not hinder the free movement of the toes.
• the front edge of the forefoot Belt 3 lies on the gradation 10C of the sole thickness of the front sole section 10.
• the incisions 13 lying one behind the other in the longitudinal direction of the sole are at a mutual distance of about one and a half centimeters. As shown in Fig. 2, these cuts can be closer together in the ball area than in the rest of the previous sole section, which corresponds to the given bending requirements.
• Fig. 3 shows a preferred embodiment of the sandal in side view, namely Fig. 1, and corresponding parts of the sandal in Fig. 3 are provided with the same reference numerals as in Fig. 1.
• the preferred embodiment according to FIG. 3 has, in addition to the forefoot strap 3, a second forefoot strap 4, which is fastened just behind the seam 12 on the rear sole section 11, and the two forefoot straps 3 and 4 are connected to one another and to the ankle strap 2A by a connecting strap 5 .
• the heel counter 2 is reduced to a narrow strip which is fastened to the rear end of the rear sole section 11.
• the sole thickness is extended at the front end of the front sole section 10 in that the lower layer 10B is shorter than the upper layer 10A.
• the length of the sandal can be somewhat shorter at the front end compared to the representation in FIGS. 1 and 3.
