Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.
[0024] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0025] Example 1
[0026] As Figures 1 to 4 shown, this embodiment provides a double - density sole structure, including a first density layer 1; a second density layer 2; the second density layer 2 is arranged at the lower end of the first density layer 1; a heel support piece 3; one end of the heel support piece 3 is connected to the first density layer 1, and the other end of the heel support piece 3 is connected to the second density layer 2; a rubber sole 4; the rubber sole 4 is arranged at the lower end of the first density layer 1, and the rubber sole 4 is connected to the second density layer 2.
[0027] In this embodiment, the first density layer 1 is arranged above, corresponding to the front part of the sole supporting the foot; the second density layer 2 is arranged below, corresponding to the heel part of the sole supporting the foot; the adhesion between the first density layer 1 and the second density layer 2 has a certain 3D space design, and the space design can bring a certain visual innovation to the sole structure; their densities and positions are different, so that the sole structure can meet different stress conditions during wearing, with better wearing comfort, and at the same time, the sole structure is not easily distorted; the heel support piece 3 is arranged at the rear end position of the sole structure, which can support the rear end of the sole structure and is not easily deformed; the rubber sole 4 is arranged at the bottom of the sole structure, which can play an anti - slip role.
[0028] Further, the first density layer 1 is a first EVA foam material layer. The hardness of the first EVA foam material layer is 55HA - 65HA.
[0029] In this embodiment, the first EVA foam material layer is measured using the Shore A hardness (denoted as HA) unit. The first density layer 1 is made of EVA foam material with a hardness between 55HA and 65HA. Its hardness is relatively low and is suitable for supporting the front part of the foot.
[0030] Further, the second density layer 2 is a second EVA foam material layer. The hardness of the second EVA foam material layer is 70HA - 80HA.
[0031] In this embodiment, the second EVA foam material layer is also measured using the Shore A hardness (denoted as HA) unit. The second density layer 2 is made of EVA foam material with a hardness between 70HA and 80HA. Its hardness is relatively high and is suitable for supporting the heel part of the foot.
[0032] Further, a card slot is arranged on the upper surface of the first density layer 1; a plastic support piece 5 is arranged in the card slot.
[0033] In this embodiment, the card slot is arranged at the middle waist position on the upper end face of the first density layer 1, and the plastic support sheet 5 is installed in the card slot.

[0034] Further, the heel support sheet 3 is a TPU foam material layer.
[0035] In this embodiment, the heel support sheet 3 is made of TPU foam material. The heel support sheet 3 is respectively connected to the first density layer 1 and the second density layer 2, and can support the rear end of the sole structure and is not easily deformed.
[0036] Further, the rubber outsole 4 is a super wear-resistant material layer. An anti-slip layer is arranged at the bottom of the rubber outsole 4; anti-slip lines 6 for increasing the surface roughness are arranged on the anti-slip layer.
[0037] In this embodiment, the rubber outsole 4 is made of super wear-resistant material. An anti-slip layer is arranged at the bottom of the rubber outsole 4, and the anti-slip lines 6 with a certain design texture are arranged on the surface of the anti-slip layer. The frictional force at the bottom of the rubber outsole 4 can be increased through the anti-slip lines 6, and the sole structure is safer and more reliable to use.
