A non-slip uneven portion 24 is formed on the surface of the fourth impact absorbing material 21 so as to be a groove in the left-right direction.

  For example, as also shown in FIG. 6, the second thin portion S2 and the third thin portion S3 are curved or valley-shaped in the surface of the inner side lateral pad portion 3 and the outer side lateral pad portion 4. By being bent, the inner lateral pad portion 3 and the outer lateral pad portion 4 are deformed so as to rise upward.

  In the embodiment, the center bottom pad portion 2 is adhered to the upper surface of the main body sheet 5, the shock absorbing material 7 is adhered to the lower surface of the main body sheet 5, and the upper surface of the central bottom pad portion 2 and the main body sheet 5 is a polyester cloth 24. It adheres by bonding, and there is no sense of discomfort even when wearing shoes with antibacterial, deodorizing, water absorption, quick drying, bare feet. Although the inner side lateral pad portion 3 and the outer side lateral pad portion 4 are named as an impact absorbing material by using an impact absorbing material, a low resilience soft material may be used. The two different material members may be composed of the low resilience soft material 6 and the impact absorbing material 7 having high repulsion as compared with the low resilience member 6.

  In the embodiment, the main sheet 5 made of polyurethane resin is laminated on the entire surface of the center bottom pad 2 made of the low resilience soft material 6, and the shock absorbing material 7 made of polyurethane resin is used as the center bottom pad 2 The main sheet 5 and the shock absorber 7 may be integrally formed of polyurethane resin material of 3 mm in thickness. is there. While using the main-body sheet 5 and the impact-absorbing material 7 of the same shape as the center bottom pad part 2, these may be bent to obtain a predetermined effect. Note that changes can be mitigated by connecting arcs.

In the embodiment, the first shock absorbing material 12, the second shock absorbing material 14, the third shock absorbing material 17, and the fourth shock absorbing material 21 are formed of the same material and at the same height. It is sufficient to select an appropriate material and to determine the optimum height in accordance with the use site.
The two different material members may be made of the low resilience soft material 6 and the impact absorbing material 7 having high resilience as compared with the low resilience member 6. The main sheet 5 may be made of a low repulsion hard material.

  The center bottom pad portion 2 is composed of an expanded front bottom pad portion 8 located at the front and an expanded rear bottom pad portion 9 located at the rear of the front bottom pad portion 8. The lateral arch A1 at the substantially tip of each metatarsal bone 25 is assisted by the front bottom pad portion 8 in the mounted state, and the lateral arch A2 at the tarsal bone 26 is assisted by the rear bottom pad portion 9 and further on the shin side The inner lateral pad portion 3 and the outer lateral pad portion 4 are in contact from both sides in the foot width direction with respect to both side surfaces of the metatarsal bone 27 and the metatarsal bone 28 on the heel side.

  The center bottom pad portion 2 is constituted by the front bottom pad portion 8 located at the front and the back bottom pad portion 9 located at the rear of the front bottom pad portion 8 and which can be bent. The provision of the three and the lateral lateral pad portion 4 allows the four pads to be provided in a substantially independent state, appropriately following changes in the shape of the dynamic foot sole during walking, and assisting walking. It is possible to cope with the bottom T such as high heels K as well.

  In addition, the lateral bottom arch A1 at the approximate tip of each metatarsus 25 and the lateral arch A2 at the tarsal bone are assisted by the central bottom pad portion 2 to have a walking assistance effect. It is important to assist these two lateral arches in terms of shock absorption and foot function of the foot. “Basic knowledge of good shoes (revised 11th edition) Is disclosed in

  It is a feature of the present invention that the two lateral arches described above can be substantially independently assisted, whereby dynamic foot sole shape change during walking even when walking using high heels K etc. By appropriately following, each lateral arch is assisted at each bottom pad portion, and excellent walking assistance is possible. Moreover, since the medial lateral pad portion 3 and the lateral lateral pad portion 4 are applied to both sides of the tibial metatarsal bone and the lateral metatarsal bone, the shins, heels, and both metatarsal bones are It will be assisted by each horizontal pad part in a wide range in the length direction.

  Furthermore, by holding the two horizontal arches by the front and rear bottom pad portions 8 and 9 and the action of effective pressing force from both sides in the foot width direction by the inner and outer lateral pad portions 17 and 21, the foot is thickened up and down. The arch height of the metatarsal can also be increased by the arch. This is important not only for foot health but also for shoe fitting.

  When the shoe insole pad 1 is used, five toes project forward from the front bottom pad portion 8 so that the five toes ride directly on the insole of the shoe. Since the tip of the shoe in which the toe is stored is not narrowed by the insole, the toe is not unnecessarily compressed. In addition, since the toes are placed directly on the insole of the shoe, the force accompanying the kicking motion of the toes can be efficiently transmitted to the insole during walking, and the walking can be performed efficiently and the shoe is worn. The sense can be maintained well.

  When the shoe insole pad 1 is used, the heel protrudes rearward from the rear bottom pad portion 9 so that the heel rides directly on the insole of the shoe. The depth dimension of the rear end portion of the shoe in which the bag is stored is not reduced by the insole 1, and by wearing the insole 1, the shoe K is not removed.

  The front bottom pad portion 8 has a shape in which the protruding height is approximately at the highest in the central portion, and in use, is located below the connecting portion of each metatarsal with the rib, As the connection between the ankles and the ribs is stably supported by the front bottom pad, as a result, the lateral arch A1 at the tip of each metatarsal is more effectively assisted.

  The insole pad 1 having such a structure is attached to the high heels K, for example, as shown in FIGS. 7 to 10. The high heel K has a heel 29 at the rear end where the heel rests, and is provided with an insole T which is sloped so as to become higher gradually from the front where the toe of the toe rests to the back where the heel rests. An upper 30 covering the entire circumference of the toes, insteps, heels, etc. is provided standing up from the outer peripheral edge of the insole 29 or the like, and the foot is inserted into a portion surrounded by the insole T and the upper 30 An accommodating portion 31 is formed.

  The insole pad 1 is inserted into the accommodating portion 31 from the opening of the upper 30 in the high heel K, and the front bottom pad portion 8 is mounted so as to face the front of the high heel K and the first thin portion S1 is a valley. By being curved like a shape, the shock absorbing material 7 is positioned so as to overlap the surface of the insole T so as to conform to the shape of the curved insole T. At this time, if necessary, fixing may be performed using a double-sided tape.

  In this way, in the high heel K on which the insole pad 1 is mounted, the front sole pad portion 8 assists the front metatarsal arch A1 as the lateral arch A1 at the approximate tip of each metatarsal bone 25. It has become. As a result, the arch of the foot is effectively maintained while being assisted from below by the front bottom pad portion 8 so that the anterior metatarsal arch A1 has a correct arch shape.

  In addition, three arches 32 constituting part of the tarsal bone 26 and a transverse arch A2 as a transverse arch A2 in the cubic bone 33 are assisted by the rear bottom pad 9. As a result, the arch of the foot is effectively maintained while being assisted from below by the rear bottom pad portion 9 so that the transverse arch A2 as the lateral arch A2 has a correct arch shape.

  The arches of the anterior metatarsus arch A1 and the cross arch A2 are held by the bottom pads 8 and 9 of the front and rear shapes, so that the original function of the foot is effectively exhibited, and shock absorption, weight shift, etc. Will be performed normally and will contribute to foot health. In addition, the arch shape of the two arches A1 and A2 is positively maintained, so that the unhealthy foot spread in the horizontal direction can be sufficiently secured instep height, as a result, the accommodation portion of the foot The foot inserted in the foot is held by the insole T of the shoe K and the upper 30 in the upper part of the foot so as to be sandwiched from the upper and lower sides, and the foot is not only in the foot width direction but also in the upper and lower height direction By being held by the inner surface of the shoe, it fits around the entire circumference including the lower surface and the upper surface of the foot to fit the inner surface of the shoe, and an excellent fitting to the shoe while maintaining good health of the foot This makes it possible to effectively suppress, for example, unpleasant flaps and the like in the shoes of the foot during walking.

  Furthermore, the inner lateral pad portion 3 is adapted to be applied to the side of the metatarsal bone 27 on the shin side from the middle portion in the front-rear direction to the rear. Further, the outer lateral pad portion 4 is applied to the side of the metatarsal bone 28 on the heel side from the middle portion in the front-rear direction to the rear. When the foot is inserted into the storage portion, the front end edge of the inner lateral pad portion 3 is positioned substantially rearward of the metatarsal bone 27 on the shin side, and the lateral lateral pad portion The front end edge of 4 is positioned substantially posterior to the heel metatarsal bone 28.

  Thereby, both sides of the foot are protected by the inner lateral pad portion 3 and the outer lateral pad portion 4 so that the arch shape of the anterior metatarsal arch S1 and the transverse arch S2 is more advantageously retained.
