[0038] Example

[0039] Please refer to Figure 1-3 As shown, this embodiment provides an elastic leisure shoe sole, including a midsole 1 and an outsole 2, the outsole 2 being attached and fixed to the bottom surface of the midsole 1. An elastic groove 11 is provided on the side of the midsole 1, and the elastic groove 11 extends along the length direction of the midsole 1. Figure 1 and Figure 3 As shown, a flexible support strip 12 and a rigid support member 13 are disposed within the elastic groove 11. The rigid support member 13 is located outside the arch of the foot. The upper and lower ends of the flexible support strip 12 are respectively affixed to and secured to the upper and lower sides of the elastic groove 11. The bottom surface of the outsole 2 is provided with a plurality of first protrusions 24, distributed across the width of the bottom surface of the outsole 2. In this embodiment, the rigid support member 13 is a TPU support block.

[0040] Streamlined elastic grooves 11 are provided on the sides of the midsole 1, giving it excellent elasticity. Flexible support grooves support the upper and lower sidewalls of the elastic grooves 11, providing upward support when the midsole 1 is subjected to downward forces, thereby enhancing its elasticity. Multiple first ridges 24 are also provided on both sides of the bottom width of the outsole 2, effectively increasing the contact area between the outsole 2 and the ground. This ensures that the outsole 2 provides excellent support for the foot. The rebound of the first ridges 24 also enhances the elasticity of the outsole 2, ensuring excellent elasticity and shock absorption for the elastic casual shoe sole. Furthermore, hard support members 13 are provided on the sides of the midsole 1, located outside the arch of the foot, providing support to the outside of the foot, preventing sprains and reducing the risk of ankle sprains during exercise.

[0041] Please refer to Figure 2 As shown, in this embodiment, the outsole 2 includes a front outsole 21 and a mid-outsole 22. The front outsole 21 corresponds to the toes, while the mid-outsole 22 corresponds to the arch. A first support arm 221 and a second support arm 222 are provided on both sides of the front end of the mid-outsole 22, extending toward the front outsole 21. The mid-outsole 22, the first support arm 221, and the second support arm 222 are all spaced apart from the front outsole 21.

[0042] The spacing between the front outsole 21 and the midsole 22 creates a gap at the rear end of the toes of the forefoot, facilitating the overall bending of the outsole 2 and midsole 1, improving overall flexibility and reducing the reaction force exerted on the foot by the outsole 2 and midsole 1 during walking, making exercise more labor-efficient. The first support arm 221 and the second support arm 222 extend toward the front outsole 21, providing support for the front edge of the midsole 1, ensuring that the entire casual shoe sole provides good support for the foot. This also reduces the contact area between the midsole 1 and the ground, improving overall wear resistance.

[0043] Furthermore, the outsole 2 includes a rear outsole 23, which corresponds to the rear end of the heel. A third support arm 223 and a fourth support arm 224 are provided on either side of the rear end of the midsole 22, extending toward the rear outsole 23. The midsole 22, the third support arm 223, and the fourth support arm 224 are all spaced apart from the rear outsole 23.

[0044] The spacing between the midsole 22 and the rear outsole 23 ensures good flexibility at the heel, facilitating bending at the heel. This reduces the reaction force exerted on the foot by the foot and the midsole during walking, further enhancing the shoe's effortless nature during exercise. The third and fourth support arms 223 and 224 extend toward the rear outsole 23, providing combined support for the rear edge of the midsole 1. This further ensures the sole provides good support for the foot, protects the midsole 1, and improves overall wear resistance.

[0045] In this embodiment, the bottom surface of the midsole 1 is provided with an outwardly protruding sole protrusion 14 and a heel protrusion 15. The sole protrusion 14 extends between the midsole 22, the first support arm 221, the second support arm 222, and the front outsole 21; the heel protrusion 15 extends between the midsole 22, the third support arm 223, the fourth support arm 224, and the rear outsole 23. The sole protrusion 14 is located below the forefoot, and the heel protrusion 15 is located below the heel. This reduces the hardness of the casual shoe sole below the forefoot and the backfoot, exerting greater elastic force on the foot during walking.

[0046] Both the sole protrusion 14 and the heel protrusion 15 are provided with a plurality of second protrusions 141, distributed in the middle or at the edges of the sole protrusion 14 and the heel protrusion 15. The second protrusions at the edges connect to the first protrusions 24 on the same side. The first protrusions 24 and the second protrusions 141 work together to increase the contact area between the sole and the ground, improving the slip resistance of the sole. Furthermore, the second protrusions and the first protrusions at the edges contact and support each other, reducing the risk of wear and tear on the first protrusions due to their short length.

[0047] The front outsole 21 is provided with at least one front notch 211. In this embodiment, there are two front notches 211, but one or more may also be provided. The two front notches 211 are located at opposite ends of the width of the front outsole 21. The front notches 211 reduce the rigidity of the front outsole 21, allowing the foot to better drive the front outsole 21 to bend during walking, further ensuring that the casual shoe sole is more energy-saving during walking.

[0048] The rear outsole 23 is provided with at least one rear notch 231. In this embodiment, there is only one rear notch 231, but two or more rear notches 231 may also be provided. The rear notch 231 reduces the hardness of the rear outsole 23, allowing for better bending of the rear outsole 23 when the heel lands, further ensuring that the casual shoe sole is more energy-saving during walking.

[0049] In this embodiment, an arch notch 225 is defined in the midsole 22, located below the arch of the foot. A decorative protrusion 16 is provided on the bottom surface of the midsole 1. The arch notch 225 reduces the hardness of the midsole 22 at the arch of the foot, facilitating bending and improving the flexibility of the casual shoe sole. Furthermore, the decorative protrusion 16 provided in the arch notch 225 enhances the sole's support for the foot. This area can also be used to create a logo-like protrusion for brand promotion.

[0050] Figure 2 The middle thick lines are the edge lines of the front outsole 21 , the middle outsole 22 and the rear outsole 23 as well as the front notch 211 , the rear notch 231 and the arch notch 225 .

[0051] Please refer to Figure 4 As shown, this embodiment also discloses a leisure shoe, comprising the elastic leisure shoe sole and an upper 3 , wherein the upper 3 is fixed on the top surface of the midsole 1 .

[0052] The upper 3 is provided with a plurality of tightening grooves 31, which extend from one side of the upper 3 through the toe to the other side of the upper 3. In this embodiment, there are three tightening grooves 31. The tightening grooves 31 tighten the upper 3, making it fit more closely to the foot, while also increasing the elasticity of the upper 3 and providing a better fit around the foot.
