Embodiment 1
[0039] A kind of self-adjusting breathable shoes, refer to figure 2 , which includes a sole 2, an upper 1 and an insole 3, and the upper 1 is made of leather. A number of ventilation holes 11 are evenly opened on the shoe upper 1 and located at the toe part.
[0040] refer to figure 2 with image 3 , the inner wall of each vent hole 11 is provided with a heat-shrinkable and cold-expandable material layer 111, and the thickness of the heat-shrinkable and cold-expandable material layer 111 is most suitable to account for 1 / 10 to 4 / 5 of the radius of the vent hole 11. In this embodiment The thickness of the heat-shrinkable cold-expandable material layer 111 is one-third of the radius of the vent hole 11 . Utilizing the characteristics of heat-shrinkable and cold-expandable material shrinking when heated and increasing volume during pre-cooling, the vent hole 11 can adjust the aperture size of the vent hole 11 according to the change of ambient temperature, so as to keep the ...
Embodiment 2-7
[0055] A self-adjusting breathable shoe, all based on Embodiment 1, the difference from Embodiment 1 is that the raw material composition of the heat-shrinkable and cold-expandable material layer 111 is different, as shown in Table 1,
[0056] Table 1.
[0057]
[0058] The ratio of the thickness of the heat-shrinkable and cold-expandable layer to the radius of the vent hole is different, and the ratios in Examples 2-7 are 4 / 5, 1 / 2, 1 / 10, 1 / 4, 1 / 3, and 1 / 3.
Embodiment 8-10
[0060] A self-adjusting breathable shoe, all based on Embodiment 1, the difference from Embodiment 1 is that the raw material composition of the heat-shrinkable and cold-expandable material layer 111 is different, as shown in Table 2,
[0061] Table 2.
