AI Technical Summary
Existing outdoor sports shoes have insufficient anti-slip and cushioning properties in complex and varied outdoor terrains, and cannot be designed differently according to the stress characteristics of different areas of the foot, resulting in easy slipping in rugged or wet environments.
A zoned anti-slip outdoor sports shoe sole was designed, including the forefoot, heel, and arch transition areas, with radial fan-shaped protrusions, annular array columnar protrusions, and long olive-shaped protrusions respectively. Combined with a gradient cushioning and abrasion-resistant layer, modified TPU, EVA, and thermoplastic elastomer materials are used to achieve dynamic adaptation to terrain.
It improves the grip and comfort of the sole, enhances the anti-slip effect on wet or loose terrain, extends the service life, and optimizes movement control.

Abstract
Claims
1. An outdoor sports shoe sole, characterized by: The shoe includes a sole base, a gradient cushioning and abrasion-resistant layer, and a zoned anti-slip layer arranged sequentially from top to bottom. The sole base includes a forefoot area, a heel area, and an arch transition area. The gradient cushioning and abrasion-resistant layer is embedded between the sole base and the zoned anti-slip layer. The zoned anti-slip layer includes forefoot anti-slip units, heel anti-slip units, and arch anti-slip units respectively fixed on the forefoot area, heel area, and arch transition area. The forefoot anti-slip units have a radially distributed fan-shaped protrusion structure, the heel anti-slip units have a ring-array of columnar protrusion structures, and the arch anti-slip units have a long, olive-shaped protrusion structure. Each protrusion of the forefoot anti-slip unit, heel anti-slip unit, and arch anti-slip unit is provided with anti-slip tendrils.
2. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The gradient buffer wear-resistant layer includes a surface wear-resistant layer, a middle buffer layer, and a bottom bonding layer. The surface wear-resistant layer is made of modified TPU material with a thickness of 0.8-1.2mm. The middle buffer layer is made of EVA or rubber composite foam material with a thickness of 2.0-3.0mm. The bottom bonding layer is made of thermoplastic elastomer material with a thickness of 0.5-0.8mm.
3. An outdoor sports shoe sole as claimed in claim 2, characterized in that: The thickness of the middle buffer layer in the forefoot area is 0.3-0.5 mm thicker than the thickness of the middle buffer layer in the heel area.
4. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The height of the raised structure of the forefoot anti-slip unit is 2.5-3.5mm, the height of the raised structure of the heel anti-slip unit is 3.0-4.0mm, and the height of the raised structure of the arch anti-slip unit is 1.5-2.0mm.
5. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The anti-slip whiskers include several groups evenly distributed along the side wall of the protrusion. The protrusion has a deformation cavity inside, and the side wall of the protrusion has several reserved through holes communicating with the deformation cavity. One end of the anti-slip whisker is fixedly connected to the deformation cavity, and the other end extends outward from the reserved through hole and the extension length is adjusted according to the pressure of the protrusion.
6. An outdoor sports shoe sole as claimed in claim 5, characterized in that: The anti-slip tendons are inclined at 30-45° along the side wall of the protrusion. When the protrusion is in its natural state, the end of the anti-slip tendons does not exceed the protrusion surface. When the protrusion is under pressure, the end of the anti-slip tendons extends 0.5-1.0 mm beyond the protrusion surface.
7. An outdoor sports shoe sole as claimed in claim 5, characterized in that: An elastic support member is fixedly installed inside the deformation cavity. The elastic support member is a cross-shaped structure made of TPU material.
8. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The surface of the fan-shaped protrusion structure of the forefoot anti-slip unit is provided with anti-slip grooves, and the anti-slip grooves are provided with diamond-shaped anti-slip particles.
9. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The top of the columnar protrusion of the heel anti-slip unit is provided with a hemispherical contact point, and a guide groove is formed between adjacent columnar protrusions.
10. An outdoor sports shoe sole as claimed in claim 1, characterized in that: The surface of the long, olive-shaped protrusions of the arch support unit is provided with serrated patterns.
