Therefore, those skilled in the art have provided a lightweight sole with secondary EVA to solve the problems raised in the above background technology. Utility Model Content

[0003] The purpose of the utility model is to provide a lightweight sole with secondary EVA to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] See also Figures 1 to 4 The utility model provides an embodiment, a lightweight sole with secondary EVA, comprising a fixed rubber upper 1, wherein the fixed rubber upper 1 is embedded with a secondary EVA sole 14, and the forefoot surface of the fixed rubber upper 1 is partitioned and connected with four diamond-shaped wear-resistant rings 11, and the wear-resistant ring 11 is partitioned and connected with an elastic rubber drum point 10, and the diameter of the elastic rubber drum point 10 is smaller than that of the wear-resistant ring 11, and a group of exhaust grooves 9 are opened on the surface of the wear-resistant ring 11, and the wear-resistant ring 11 can pass through the exhaust groove 9. By arranging the elastic rubber drum point 10 in the wear-resistant ring 11, the elastic rubber drum point 10 can expand to the surroundings when squeezed, thereby increasing the contact area between the elastic rubber drum point 10 and the ground. When there is water on the bottom, the water can be discharged from the elastic rubber drum point 10, and at the same time, the wear-resistant ring 11 can limit the expansion range of the elastic rubber drum point 10, thereby providing it with an upward force to resist the recoil force received by the user's foot, thereby increasing the cushioning effect.

[0024] In an embodiment, the fixed rubber upper 1 has a top wear-resistant pad 2 at the toe, and the fixed rubber upper 1 is fixedly connected to a group of partition wear-resistant pads 12 on the sole surface, and the partition wear-resistant pads 12 are located on both sides of the wear-resistant ring 11. The fixed rubber upper 1 is fixedly connected to the sole surface of the foot with side anti-slip pads 3, and the side anti-slip pads 3 are located below the top wear-resistant pad 2, and are also located on one side of the wear-resistant ring 11 and the partition wear-resistant pad 12. By arranging the fixed rubber upper 1 on the top, the fixed rubber upper 1 can better prevent damage to the front when the user uses the sole, thereby increasing the service life. At the same time, the partition wear-resistant pads 12 are placed on both sides of the wear-resistant ring 11, and the side anti-slip pads 3 are located on the other side of the wear-resistant ring 11, which can further improve the friction and service life of the sole.

[0025] In an embodiment, the heel surface of the fixed rubber upper 1 is fixedly connected to a group of bottom wear-resistant pads 8, a reserved groove 13 is opened at the center of the heel surface of the fixed rubber upper 1, a logo fixing block 6 is fixedly connected in the reserved groove 13, and the bottom wear-resistant pad 8 is located on the left and right sides of the reserved groove 13,

[0026] In the embodiment, the secondary EVA sole 14 adopts secondary foamed EVA material, and the secondary EVA sole 14 is integrally formed with the fixed rubber upper 1, and a certain gap is set between the top wear-resistant pad 2, the side anti-slip pad 3, the partition anti-slip pad 4, the first filling anti-slip pad 5, the identification fixing block 6, the bottom wear-resistant pad 8, the wear-resistant ring 11 and the partition wear-resistant pad 12. Moisture can be drained through this gap, thereby further improving the anti-slip effect. The use of secondary foamed EVA material can improve the use effect of consumers.

[0027] The sole is composed of a fixed rubber upper 1 and an embedded secondary EVA sole 14. The secondary EVA material provides a good cushioning effect. Four wear-resistant rings 11 are provided in the forefoot area of the shoe. These wear-resistant rings 11 are combined with the elastic rubber drum 10 to form a unique contact mechanism. By setting gaps between different components, the discharge of moisture can be further promoted and the anti-slip performance can be improved. The wear-resistant rings 11 limit the expansion range of the elastic rubber drum 10. In this way, when the user's foot is stressed, the wear-resistant rings 11 can provide an upward force to help offset the recoil force, improve comfort and cushioning effect, and at the same time, multiple anti-slip pads and wear-resistant pads can further improve the use effect of the product.

[0028] By using the elastic rubber drum 10, after the elastic rubber drum 10 contacts the ground, it is squeezed from the contact point and expands to the surrounding area, thereby allowing more area to contact the ground, thereby increasing the anti-slip effect of the sole and improving the consumer's use experience;

[0029] At the same time, wear-resistant pads are used more in high-frequency contact areas to reduce wear on the soles and increase the service life of the shoes. At the same time, there are gaps between all anti-slip pads and wear-resistant pads to drain moisture from the bottom and further enhance the anti-slip effect.

[0030] This specification is described in terms of implementation methods, but not every implementation method contains only one independent technical solution. This narrative style of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
