[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figures 1 to 5 The present invention provides an insole, comprising an insole body 1, wherein the thickness of the insole body 1 gradually decreases from the outer edge of the insole body 1 at the arch of the foot to the inner direction, and the insole body 1 is provided with two or more layers of massage circles 2 arranged inwardly from the contour edge of the insole body 1 on the side facing the sole of the human foot, and the shape of the massage circle 2 is the same as the outer edge contour of the insole body 1; an annular channel 3 is formed between two adjacent layers of the massage circles 2 to facilitate the airflow of the sole to flow along an annular trajectory. The present invention forms an annular channel 3 in each massage circle 2, and the annular channels 3 are connected to form a ventilation channel, so that the sole of the foot is always ventilated and dry when worn, effectively preventing water and sweat accumulation on the sole of the foot, and improving the wearing comfort of the human body.

[0039] Specifically, in order to facilitate the circulation of air underfoot, the annular channels 3 are interconnected, and the shape of the annular channels 3 is the same as the outer edge contour of the insole body 1 , so that the airflow under the sole circulates along the annular channels 3 .

[0040] In this embodiment, the annular channel 3 corresponding to the arch of the sole of the human body is provided with an air inlet 301 that allows air to flow from the arch of the sole into the annular channel 3, so that air can enter between the insole body 1 and the sole through the air inlet 301 at the edge of the sole; at the same time, Figure 2As shown, the insole body 1 is provided with an arch protrusion 6 corresponding to the arch of the sole of the human foot. The arch protrusion 6 is an EVA foam material and the height of the arch protrusion 6 gradually decreases from the arch edge of the insole body 1 to the inside. The arch protrusion 6 is fixedly connected to the insole body 1. A gap for air circulation is formed inside the EVA foam material, so that air can also enter between the insole body 1 and the sole of the foot from the arch of the sole. The design of the arch protrusion 6 gradually decreasing from the arch edge of the insole body 1 to the inside allows the air between the insole body 1 and the sole of the foot to circulate from the arch to other parts of the sole of the foot, which facilitates air circulation and keeps the sole of the foot dry.

[0041] Furthermore, the present invention makes the width of the annular channel 3 at the arch of the human foot greater than the width of the annular channel 3 in other areas of the sole, so that gas enters the annular channel 3 from the air inlet 301 at the arch; at the same time, the width of the annular channel 3 corresponding to the toes of the human body increases from the position corresponding to the big toe of the human toe to other toe areas, so as to facilitate the gas in the annular channel 3 to flow from the big toe to other toe areas.

[0042] In addition, the annular channel 3 corresponding to the human heel is provided with an air outlet 302 that allows air to flow out of the annular channel 3 from the sole of the foot. The height of the massage circle 2 corresponding to the human heel gradually increases from the position corresponding to the heel to the corresponding human sole area. When the human body walks or stands, due to the gravity of the heel, the air between the insole body 1 and the sole of the foot is squeezed out from the air outlet 302 at the heel.

[0043] In this embodiment, the height of the massage circle 2 corresponding to the arch of the sole of the human foot is higher than the height of the annular channel 3 in other areas of the sole of the foot, and the height of the massage circle 2 corresponding to the arch of the sole of the human foot gradually decreases from the outer edge of the insole body 1 to the inner direction, which is also beneficial to the air circulation between the insole body 1 and the sole of the foot from the arch to other parts of the sole of the foot.

[0044] The height of the massage circle 2 corresponding to the toes of the human body gradually decreases from the position corresponding to the big toe of the human body to other toe areas, so as to facilitate the air in the toe area to flow from the big toe to other toe areas.

[0045] Furthermore, in order to improve the wearing comfort of the human body, the massage circle 2 is composed of a plurality of massage protrusions 4 arranged in a ring shape, and radial channels 5 are provided between adjacent massage protrusions 4 on the same layer of the massage circle 2 to facilitate the radial flow of airflow on the sole of the foot. The design of the radial channel 5 also allows the airflow on the sole of the foot to flow between the massage circles 2.

[0046] According to the size of the human foot, the width between the adjacent massage protrusions 4 on the same layer of massage ring 2 is 0.2-1 mm, the massage ring 2 is composed of 30-80 massage protrusions 4, and the diameter of the massage protrusions 4 is 2-4 mm;

[0047] According to the size of the sole, the width between the massage protrusions 4 of the children's insole is 0.2-0.8 mm, the massage ring 2 is composed of 30-50 massage protrusions 4, and the diameter of the massage protrusions 4 is 2-3 mm;

[0048] The width between the massage protrusions 4 of the adult shoe insole is 0.7-1 mm, the massage ring 2 is composed of 50-80 massage protrusions 4, and the diameter of the massage protrusions 4 is 3-4 mm.

[0049] Furthermore, in order to improve the massage effect of the massage protrusion 4, a massage ball in a hemispherical shape is provided on the top of the massage protrusion 4.

[0050] The design that the width of the radial channel 5 corresponding to the human arch is greater than the width of the radial channel 5 in other areas of the sole is also conducive to the air circulation between the insole body 1 and the sole from the arch to other parts of the sole.

[0051] The width of the radial channel 5 corresponding to the middle of the sole of the human body gradually decreases from the middle of the sole of the human body to the corresponding heel of the human body, which is conducive to the air flow between the insole body 1 and the sole from the middle of the sole to the heel.

[0052] The width of the radial channel 5 corresponding to the human toes increases from the position corresponding to the big toe of the human toes to other toe areas, so as to facilitate the air in the toe area to flow from the big toe to other toe areas.

[0053] Furthermore, the insole body 1, the massage protrusions 4 and the massage balls are made of polyurethane, so that the insole body 1, the massage protrusions 4 and the massage balls are particularly elastic, further improving the wearing comfort.

[0054] The working principle of this embodiment is as follows: first, the user confirms the size of his or her foot, and selects an insole that matches the user according to the size of the foot. The insole is mainly provided with a plurality of groups of annular massage circles 2 on the side of the insole body 1 facing the sole of the human foot. The massage circle 2 is a cylindrical massage protrusion 4 facing the sole of the human foot, which can meet the massage of the sole of the human foot by relying on the gravity of the human body during the walking and standing process of the person, and relieve the fatigue of the human body. An annular channel 3 is provided between the massage circles 2, and a radial channel 5 is provided between the massage protrusions 4, so that the annular channel 3 and the radial channel 5 are connected to form a ventilation channel, which can be worn by the human body. During the wearing process, the sweat generated by the sole of the foot flows to the gap between the massage protrusions 4 due to gravity, so that the sole of the foot is always dry when wearing, effectively preventing water and sweat from accumulating on the sole of the foot, and improving the wearing comfort of the human body. The height of the massage protrusion 4 corresponding to the arch of the human foot gradually decreases from the outer edge of the arch of the insole body 1 to the inner side of the insole body 1, which effectively prevents flat feet. The height of the massage protrusion 4 corresponding to the big toe of the human foot is lower than the height of other massage protrusions 4, which can effectively prevent the hallux valgus. The massage protrusion 4 is made of polyurethane material, which makes the massage protrusion 4 elastic and easy to bend, thereby improving the massage effect.

[0055] Embodiment 2, the second embodiment of the present invention provides a shoe including the insole described in Embodiment 1. The principle of the second embodiment is the same as that of the first embodiment, the difference being that, in this embodiment, the insole is arranged on the upper surface of the sole of the shoe, and the shoe can be outdoor sandals, sports shoes, casual shoes, etc.
