Embodiments of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 8 show a fishing boot.
FIG. 1 shows a first embodiment to which the invention according to claim 4 is applied. In FIG. 1, reference numeral 23 denotes a waterproof boot body formed of foam rubber according to a human footprint, and 25 denotes synthetic rubber. With the formed sole, the sole 25 is vulcanized to the bottom 27 of the boot body 23 as in the past, and both are joined,
As shown in FIG. 2, a spike sole 31, which will be described later, is detachably attached to the bottom surface 29 of the sole 25 via velvet type fasteners (surface fasteners) 33, 35.

In the sole 25, a plurality of hollow portions 41 are formed in a lattice shape in the arch portion of the upper surface 39 surrounded by the side wall 37, and the grid portions 4 which define the hollow portions 41 are formed.
Reference numeral 3 is formed to be taller toward the heel.
As shown in FIGS. 2 to 4, a concave portion 45 having a substantially U-shaped cross section that opens to the bottom surface 29 is formed in the heel portion of the sole 25. The upper surface 39 of the sole 25 is formed together with the portion 43, and as shown in FIGS.
1, an elongated through hole 53 that opens to a side portion of the sole 25 is formed in the front and rear direction of the sole 25. A hollow cushion body (hereinafter, “air cushion”) having a sealed air chamber as a shock absorber made of synthetic resin such as vinyl chloride, polyurethane, thermoplastic rubber, urethane, or rubber or rubber in the recess 45. 55) and a cushion portion is provided.

As shown in FIGS. 4 to 6, the air cushion 55 is a hollow disk body having a thick air cushion main body 57. The air cushion main body 57 is formed in a shape along the concave portion 45, A hollow bulged portion 59 having a size that fits into the through hole 53 and does not protrude outward from the side surface of the sole 25 is formed integrally with the side portion of the slab.

A plurality of mortar-shaped bottomed holes 61 are provided at opposing positions on the upper and lower surfaces of the air cushion main body 57, and a closed air chamber 64 is formed by joining the bottoms 63 of the holes 61 to each other. Have been. Thus, the peripheral wall of the air chamber 64 is formed to be thin, distorted by the load, and returns to the original shape when the load is removed. The air cushion 55 can be easily mounted in the recess 45 by fitting and adhering the bulging portion 59 into the through hole 53.

As shown in FIGS. 3, 4 and 7, a concave step 65 is provided on the periphery of the concave portion 45. As shown in FIG. A thin lid 67 made of the same material as the sole 25 is adhered to the step portion 65 so as to be flush with the bottom surface 29 of the sole 25 to cover the opening of the concave portion 45. The lid 67 functions as an isolation layer that exerts a buffer function of the air cushion 55 and the velvet fasteners 33 and 35 as described later.

The air cushion 55 and the lid 67 are attached by vulcanizing the sole 25 on the bottom 27 of the boot body 23 and joining them together.
The air cushion 55 is attached to the concave portion 45 that opens to the side, and then the lid 67 is attached to the step portion 65. Thereafter, a velvet fastener 33 is attached to the bottom surface 29 of the sole 25, and the velvet fastener 33 is attached.
And velvet fastener 35 on the spike sole 31 side
Thus, the spike sole 31 is detachably attached to the bottom surface 29 of the sole 25.

As shown in FIGS. 2 and 4, the spike sole 31 is constituted by fastening a plurality of spikes 71 formed by bending a metal wire into a U-shape to a hard rubber sole member 69. The tip of each spike protrudes toward the ground contact surface from an annular support portion 73 integrally formed with the sole member 69. Then, a velvet type fastener 35 is attached to the upper surface thereof.

As shown in FIG. 8, the velvet fastener 33 adhered to the bottom surface 29 of the sole 25 is a so-called "male type" provided with a large number of synthetic resin fibers 75 projecting in a hook shape. The velvet type fastener 35 on the sole 31 side has a so-called “female type” structure provided with a number of synthetic resin fibers 77 projecting in a loop shape.
5, 77 have a space between each fiber, and these fibers 7
5, 77 have a restoring action due to their elasticity even when bent by a load, so that they function as a buffer layer for mitigating the push-up caused by the spike 71 during walking by a soft cushioning action.

Although not shown, the bottom surface 2 of the sole 25 is not shown.
9 has a spike sole 3 similar to the conventional example shown in FIG.
Instead of 1, another type of sole member having a rubber material or felt attached to the grounding surface can be attached and detached via a velvet type fastener, and the spike sole 31 and other sole members are selected according to the fishing spot. It is possible to replace the spike sole with a new spike sole when the spike 71 wears out.

Since the boot 79 according to the present embodiment is configured as described above, the spike 71 cuts into the ground at the fishing ground, stops slipping, and firmly protects the feet. Conventional boots equipped with a spike sole are not comfortable to wear due to the spike being pushed up on a hard ground or a rocky ground or a shock at the time of landing. However, in the present embodiment, a buffer layer including velvet type fasteners 33 and 35 and an air cushion are provided. The cushions 55 absorb and alleviate the shock at the time of pushing up the spikes 71 and landing, respectively, and alleviate the feeling of pressure on the feet.

At this time, the lid 67 is made up of the velvet type fasteners 33 and 35 as buffer layers and the air cushion 5.
By interposing it like a hard partition plate and supporting them widely, the respective cushioning functions of the two can be exhibited well. Therefore, after the primary shock is reduced by the buffer layer supported by the isolation layer, the shock transmitted through the isolation layer is further alleviated by the air cushion 55.

Further, even if a force such as a lateral force is applied to the spikes 71 to defeat them, the velvet fasteners 33 and 35 serving as buffer layers and the air cushion 55 absorb and reduce such forces. Thus, the spike sole 31 is prevented from being damaged due to the spike 71 falling off. Thus, according to the present embodiment, the velvet fastener 3
The cushion layer made of 3, 35 and the air cushion 55 absorb and mitigate the shock when the spike 71 is pushed up or lands, respectively, so that the feeling of pressure on the foot is reduced as compared with conventional boots equipped with a spike sole, The comfort was extremely good.

As described above, even if a force other than the longitudinal direction is applied to the spike 71, the velvet type fasteners 33 and 35 and the air cushion 55 absorb such a force.
Since the spikes 71 are alleviated, there is an advantage that the spike soles 31 can be prevented from being damaged due to the spikes 71 falling off.

Further, according to the present embodiment, it is not necessary to increase the thickness of the sole 25 in order to reduce the shock at the time of pushing up the spike 71 and landing, so that the boot 79 does not become heavy. In the above-described embodiment, the spike sole 31 is detachably attached to the sole 25 by the velvet fasteners 33, 35, and the spike soles 31 and 35 function as a buffer layer by using the soft cushioning action of the velvet fasteners 33, 35. However, instead of the detachable spike sole 31, a configuration in which a plurality of spikes are directly fixed to the bottom surface of the sole may be adopted.

In this configuration, instead of the velvet fasteners 33 and 35, for example, a woven fabric, a nonwoven fabric made of synthetic resin fibers, or a laminate of these,
Also, the fibers may be planted on the sheet and interposed between the air cushion and the spikes, or the fibers may be directly planted on the upper surface of the sole to form a buffer layer. FIGS. 9 and 10 show a second embodiment in which the invention according to claims 1 to 4 is applied to a fishing boot. In this embodiment, the same material as that of the air cushion 55 is used. Is formed in a hollow bag made of one air chamber 83, and T
The spike 85 is fixed to the sole member 69 to form the spike sole 87.
1, the spike sole 87 is provided on the bottom surface 29 of the sole 25.
Are detachable via velvet fasteners 33 and 35.

The other configuration is the same as that of the above-described first embodiment, and therefore, the same components are denoted by the same reference numerals and description thereof will be omitted. Boot 8 according to the present embodiment
9 is configured as described above, and in this embodiment,
The cushion layer made of the velvet type fasteners 33 and 35 and the air cushion 81 absorb and reduce the shock at the time of the spike 85 being pushed up and landing, respectively, and alleviate the feeling of pressure on the foot. By interposing the velvet type fasteners 33 and 35 as layers and the air cushion 81 like a hard partition plate to widely support them, the respective cushioning functions of both can be exhibited well.

Therefore, after the primary shock is alleviated by the buffer layer supported by the isolation layer, the shock transmitted through the isolation layer is further alleviated by the air cushion 81. Further, even if a force such as a lateral force is applied to the spikes 85 to defeat them, the velvet fastener 33,
35 and the air cushion 81 absorb and alleviate such a force, thereby preventing the spike sole 87 from being broken due to the spike 85 falling off.

Therefore, according to the present embodiment, as in the case of the boot 79 of FIG. 1, the feeling of pressure on the foot is reduced as compared with the conventional boot, so that the wearing comfort is extremely good, and the spike 8
5 can be prevented from being damaged. In each of the above embodiments, the concave portion 45 is opened on the bottom surface 29 side of the sole 25. However, a concave portion opened on the upper surface side or the lateral side of the sole may be provided, and an air cushion may be attached to the concave portion. In this case, the bottom of the recess functions as an isolation layer.

In each of the above embodiments, the air cushions 55 and 81, which are separate from the sole 25, are mounted in the concave portions 45 to form hollow cushion portions. However, these may be formed integrally with the soles. The air cushion may be attached to the upper surface of the sole, and the air cushion may be sandwiched between the bottom of the boot body and the sole. With these structures, the intended purpose is achieved similarly to the above embodiments. It is possible to

Furthermore, the present invention is not limited to fishing shoes and boots, but also golf shoes and other sports shoes having a spike on the sole, or shoes and boots for snowy roads.
Furthermore, it can be widely applied to footwear such as waders having a boot portion. In addition, in each of the above embodiments, the air cushions 55 and 81 are mounted on the heel of the sole 25.

[0031]

As described above, according to the footwear according to the first aspect, since the hollow cushion portion absorbs and alleviates the shock at the time of landing and landing of the spike, the conventional footwear having the spike on the sole can be used. The feeling of pressure on your feet is softened,
The comfort was extremely good. In addition, even if a force other than the longitudinal direction is applied to the spike, the cushion portion absorbs and reduces the force, so that there is an advantage that the sole can be prevented from being damaged due to the spike falling off.

Furthermore, since the sole does not need to be thickened to reduce the spikes, the footwear does not become heavy. According to the second and fourth aspects of the present invention, the buffer layer, in conjunction with the cushion portion, absorbs and alleviates the shock at the time of spike thrust and landing.
According to the third aspect of the present invention, the separating layer is interposed between the cushioning layer and the cushion portion like a partition plate to support the cushioning layer widely. There is an advantage that the function can be exhibited more favorably.
