The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a 3D printed outdoor shoe.

[0005] To achieve the above objectives, the technical solution of this utility model is: a 3D printed outdoor shoe, comprising an upper and a sole, the sole comprising a midsole and an outsole, the upper being fixedly connected to the midsole, the midsole being fixedly connected to the outsole on the opposite side of the upper, and several loops being provided on both sides of the upper, the loops passing through the upper and being fixedly connected to the midsole, shoelaces being threaded through the loops, the shoelaces alternately passing through the loops on both sides, the two ends of the shoelaces emerging from the loops near the shoe opening of the upper, and the shoelaces being provided with fastening members for tightening the shoelaces.

[0006] By adopting the above technical solution, the main force point of the shoelaces is transferred from the upper to the midsole. The combination of the loops and shoelaces binds the foot, thus fixing the foot inside the shoe. This method can reduce the deformation of the upper and also reduce the need for the upper's elasticity, making it better suited to 3D printed uppers.

[0007] Preferably, the tightening element is an elastic buckle, and the two ends of the shoelace pass through two holes on the elastic buckle. This invention achieves shoelace tightening through the elastic buckle.

[0008] Preferably, the shoelaces are provided with a fixing member, and both ends of the shoelaces are fixedly connected to the fixing member. This invention utilizes the fixing member to secure the two ends of the shoelaces together, making it more convenient to pull the tightening member.

[0009] Preferably, an inner sleeve is provided inside the shoe upper. This invention utilizes the inner sleeve to enhance the comfort of the shoe, while also making the shoe warmer and providing better sweat absorption through the inner sleeve's wrapping effect.

[0010] Preferably, the inner sleeve has a ribbed cuff at the entrance. This invention utilizes the ribbed cuff to allow the inner sleeve to be tightly secured around the ankle.

[0011] Preferably, the inner sleeve is fixedly connected to the shoe upper.

[0012] Preferably, the two symmetrical loops are formed on the same webbing, which wraps around the bottom of the inner sleeve, and the middle part of the webbing is fixedly connected to the insole. This utility model.

[0013] Preferably, the webbing is provided in three parts.

[0014] Preferably, one of the webbing straps is located at one end of the shoe upper opening near the toe of the shoe, another webbing strap is located on the shoe upper near the heel, and the last webbing strap is located between the other two webbing straps. This invention achieves shoe tightening with minimal loops by distributing the webbing straps in this manner.

[0015] Preferably, the upper is made by 3D printing.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. The main stress point of the shoelaces is shifted from the upper to the midsole. The combination of the loops and shoelaces binds the foot, thus fixing it inside the shoe. This reduces the deformation of the upper and the need for elasticity, allowing it to better adapt to 3D printed uppers.

[0018] 2. The combination of fastening and fixing components makes it easier to tighten the shoes.

[0031] like Figure 1 As shown, a 3D printed outdoor shoe includes an upper 1 and a sole. The upper 1 is made by 3D printing. The sole includes a midsole 2 and an outsole 3. The upper 1 is fixedly connected to the midsole 2. The midsole 2 is fixedly connected to the outsole 3 on the other side of the upper 1. Several loops 4 are provided on both sides of the upper 1. The loops 4 pass through the upper 1 and are fixedly connected to the midsole 2. Shoelaces 5 are threaded through the loops 4. The shoelaces 5 alternately pass through the loops 4 on both sides. The two ends of the shoelaces 5 emerge from the loops 4 near the shoe opening of the upper 1. The shoelaces 5 are provided with fastening members 6 for tightening the shoelaces 5.

[0032] By adopting the above technical solution, the main force application point of the shoelace 5 is transferred from the upper 1 to the midsole 2. The foot is bound by the combination of the loop 4 and the shoelace 5, thereby fixing the foot inside the shoe. In this way, the deformation of the upper 1 can be reduced, and the elasticity requirement of the upper 1 can also be reduced, which can better adapt to the 3D printed upper 1.

[0033] The fastening element 6 is an elastic buckle, and the two ends of the shoelace 5 pass through the two holes on the elastic buckle respectively. The shoelace 5 is tightened through the elastic opening.

[0034] The shoelace 5 is equipped with a fastener 7, and both ends of the shoelace 5 are fixedly connected to the fastener 7. The fastener 7 can fix the two ends of the shoelace 5 together, making it more convenient to pull the tightening member 6.

[0035] An inner sleeve 8 is provided inside the upper 1 and is fixedly connected to the upper 1. The inner sleeve 8 enhances the comfort of the shoe, while also providing better warmth and sweat absorption through its wrapping effect. A ribbed sock cuff is provided at the entrance of the inner sleeve 8. The ribbed sock cuff allows the inner sleeve 8 to be tightly secured around the ankle.

[0036] Two symmetrical loops 4 are formed on the same webbing 9, which wraps around the bottom of the inner sleeve 8 and is fixedly connected to the midsole 2 at its center. There are three webbing 9s: one located at the opening of the upper 1 near the toe, another near the heel, and the last between the other two. This distribution of the webbing 9 allows for a tighter fit with as few loops 4 as possible.

[0037] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
