The footwear 1 is formed by affixing via an adhesive layer (not shown).

When a pedestrian walks wearing the footwear 1 having such a configuration, the feet rub in the footwear 1 and heat is generated. Thereby, the far-infrared radiator dispersed in each of the temperature-sensitive adhesive layer 131a, the temperature-sensitive sheet layer 131b, and the temperature-sensitive sheet layer 133b constituting the upper portion 100 radiates received heat as far-infrared rays.
Therefore, the surface of the foot facing the inner material layer 110 constituting the upper portion 100 can be integrally warmed. Therefore, it can be set as the footwear 1 which can implement | achieve favorable warmth with a simple structure.
Furthermore, as described above, the footwear 1 according to the present embodiment has a configuration in which the insole portion 400 including the temperature-sensitive adhesive layer 421 and the temperature-sensitive sheet layer 422 is provided on the upper surface of the midsole portion 300.

Therefore, by combining the upper part 100 and the insole part 400, at least the periphery of the foot from the tip of the foot to the heel (ankle) can be integrally warmed. Thereby, the blood circulation of the foot can be improved efficiently, and not only the foot portion covered with the footwear 1 but also the entire leg portion can be warmed. Therefore, it can be set as footwear 1 which can realize much better warmth.

  Moreover, in the warm adhesive layer 131a and the warm adhesive layer 421, by providing the adhesive layer itself with a function of emitting far infrared rays, a simple configuration is preferable without adding another member to the shoe. Even when it can be used for footwear with different designs and uses (for example, men's shoes, slippers, boots, nursing shoes, etc.), it can be easily applied without increasing the manufacturing process and manufacturing costs. Can do.

In addition, the first intermediate layer 131 formed by sandwiching the temperature sensitive sheet layer 131b between the pair of temperature sensitive adhesive layers 131a and 131a is joined to the inner material layer 110, and further a temperature sensitive sheet layer that emits far infrared rays. By having a third intermediate layer formed by sandwiching 133b between a pair of adhesive layers 133a and 133a interposed between the first intermediate layer 131 and the second intermediate layer 132, A structure in which warm adhesive layers 131a and warm sheet layers 131b and 133b are alternately stacked (more specifically, two warm adhesive layers 131a and two warm sheet layers 131b and 133b) Are alternately stacked.). Therefore, it is possible to make it difficult for heat in the foot storage space to escape from the surface of the upper portion 100 to the outside, and to make the footwear 1 capable of maintaining good warmth, and to improve the strength of the footwear 1. The footwear 1 can be made durable.
In addition, the temperature sensitive adhesive layer 421 and the temperature sensitive sheet layer 422 are alternately laminated, and the far infrared radiator layer 420 is formed by the three layers of the temperature sensitive adhesive layer 421 and the two layers of the temperature sensitive sheet layer 422. By doing so, it is possible to make it difficult for the heat in the foot storage space to escape from the bottom of the footwear 1, to maintain good warmth, and to improve the strength of the footwear 1, which is durable. Good footwear 1 can be obtained.
Further, by combining the upper portion 100 and the insole portion 400, it is possible to make it difficult for the heat in the foot storage space to escape from the substantially entire circumference of the footwear 1, and it is possible to maintain a better thermal sensation and to maintain the footwear 1. The footwear 1 can be further improved, and the footwear 1 having good durability can be obtained.

  Further, the warm adhesive layer 131a and the warm adhesive layer 421 are semi-solid warm materials obtained by dispersing a far-infrared radiator that emits far-infrared rays in an adhesive mainly composed of latex and synthetic resin. By adopting a configuration formed of an adhesive, far-infrared rays can be efficiently emitted to the foot, and the footwear 1 having good cushioning properties can be obtained.

  The component composition of the latex, the synthetic resin, and the far-infrared radiator with respect to the total weight of the thermal adhesive layer 131a and the thermal adhesive layer 421 is latex: 70% to 80%, synthetic resin: 4% to 8%. , Far-infrared radiator: By setting the content to 15% to 25%, a warm adhesive layer capable of simultaneously realizing an appropriate viscosity and good far-infrared radiation can be obtained.

Further, the far-infrared radiator dispersed in the warm-sensitive adhesive layer 131a and the warm-sensitive adhesive layer 421 is a serpentine, more preferably a noble serpentine, so that the far-infrared radiation efficiency can be further improved. It can be set as the footwear 1 which can implement | achieve favorable warm feeling.
Further, when the particle size of serpentine (same for precious serpentine) is about 0.1 μm to 10 μm, it can be easily dispersed in the adhesive layer and can be contained in a large amount. Moreover, it can be set as the far-infrared radiator which cannot deform | transform easily at the time of a walk, and can maintain favorable warmth.

  Further, by forming the temperature-sensitive sheet layer 131b, the temperature-sensitive sheet layer 133b, and the temperature-sensitive sheet layer 422 with a non-woven fabric kneaded with far-infrared radiator powder that emits far-infrared rays, the processing is easy. At the same time, it is possible to provide a warm sheet layer that can reduce the manufacturing cost.

  Moreover, the thickness of a warm adhesive layer can be made thin by the thickness of the warm adhesive layer 131a and the warm adhesive layer 421 being about 1.5 mm to 2 mm. Therefore, when the pedestrian wears the footwear 1, it can be prevented that the pedestrian feels stiff. Therefore, it can be set as the footwear 1 which can implement | achieve favorable warm feeling and a fit feeling simultaneously.
