Detailed Description

The utility model proposes a new solution, which is described in detail below with reference to the accompanying drawings for a clearer representation.

The first embodiment,

Referring to fig. 1 to 3, the present embodiment provides a 3D printed hollow sole, which includes a hydrophobic midsole 10 and an anti-slip outsole 20. Hydrophobic insole 10 includes multilayer fretwork layer 101, and the fretwork hole of fretwork layer 101 is at least by a support column 1011 end to end connection shaping, and the fretwork hole of fretwork layer 101 is from top to bottom, control and link up the setting each other, and fretwork layer 101 is towards toe cap and/or heel direction support column 1011 becomes thick setting gradually. A non-slip outsole 20 is sealingly disposed on the bottom surface of the hydrophobic midsole 10.

Specifically, the anti-slip outsole 20 is attached to the bottom surface of the hydrophobic midsole 10 in a sealing manner, so that the anti-slip performance of the shoe can be improved through the structure of the anti-slip outsole 20, and the problem of easy slipping is avoided. The hydrophobic insole is formed by the multiple hollow layers 101, the hollow layers 101 are communicated with each other up and down and left and right, and then a plurality of hollow holes which can be led to the outside are formed, so that water in the shoe can be discharged from the hollow layers 101, and the hydrophobic insole has the effects of hydrophobicity and drainage. No water accumulation is formed in the shoe body, and the wearing comfort is improved.

Further, for the hollow holes on the hollow layer 101, different functional effects can be obtained through different morphological structures. For example: when the hollowed-out layer 101 becomes thick gradually towards the heel direction support column 1011 and designs, can improve the support intensity of heel department, improve the structural stability of back heel part, satisfy the characteristics that the back foot landed first when some people walked, and the design of hollowed-out structure can provide good shock attenuation effect, improves the comfort level of walking. When the hollow layer 101 is designed to be gradually thicker toward the toe cap direction support column 1011, the front sole lands first during bouncing, so that the support strength of the front sole can be enhanced, the requirement of jumping is met, and the service life of the shoe is prolonged. Similarly, when the hollowed-out layer 101 gradually thickens towards the toe cap and the heel direction support column 1011 simultaneously, the shoe sole has the characteristics of the two structures, can keep the relative flexibility of the middle part of the shoe sole, and has a certain bending effect. Therefore, different structural designs can meet the requirements of different people.

In this embodiment, the hollow holes are of a triangular structure, a quadrilateral structure, a pentagonal structure, a hexagonal structure or an elliptical structure. Of course, the hollow holes may be polygonal structures, and corresponding regular polygons, circles, squares, and the like. Oval hollow holes can be formed by connecting the support columns 1011 end to end, circular hollow holes can also be formed by two semicircular support columns 1011, three linear support columns 1011 form a triangular support column, and the support columns 1011 are connected end to end and then are polygonal. For the structure formation of the hollow hole, the setting can be set according to the requirement, for example, the triangular structure setting can provide good stability. And the elasticity of structure can be improved to oval structure setting, and then improves the shock attenuation effect of structure.

The antiskid outsole 20 in this embodiment is provided with a through hole 201 in the middle, and a sealing layer 202 which is hermetically provided on the through hole 201. Sealing layer 202 is a thermoplastic polyurethane elastomer or polyvinyl chloride.
