Embodiment I

[0038] As shown in FIGS. 1-4, a slipper having a replaceable upper, comprising a sole 1 and an upper 2, wherein left and right side edges of an upper surface of the sole 1 in a forefoot area extend upwards to respectively form a left retaining edge 11 and a right retaining edge 12, and the left retaining edge 11 and the sole 1, the right retaining edge 12 and the sole 1 are integrally formed; the left retaining edge 11 is provided with at least one left through hole 111 in the width direction of the sole 1, the right retaining edge 12 is provided with at least one right through hole 121 in the width direction of the sole 1, and two ends of the upper 2 are respectively inserted from inner side surfaces of the left retaining edge 11 and the right retaining edge 12, and correspondingly pass through the left through hole 111 and the right through hole 121 to form a detachable connection with an outer surface of the upper 2.

[0039] Preferably, two ends of the upper 2 are provided with hook-and-loop fastener 3 configured to be bonded to a plurality of bonding areas of the outer surface of the upper 2 at any position, thereby achieving quick fastening and adjustment of tightness; [0040] two ends of the upper 2 are respectively inserted from the inner side surfaces of the left retaining edge 11 and the right retaining edge 12, respectively pass through the left through hole 111 and the right through hole 121, and are then folded back to be bonded and fastened to the outer surface of the upper 2. The advantages of this design are as follows: the bonding surface of the upper 2 is located externally, thus does not press against the foot, improving the foot comfort; a visible and easily detachable design is provided, with a tear-off point visible at a glance, allowing quick replacement of the upper 2; cleaning dead corners are fewer, and the structure is simple.

[0041] Preferably, both the left retaining edge 11 and the right retaining edge 12 are recessed inwards to form curved surfaces, the curved surfaces are adapted to the curvature of two sides of the forefoot, and can better fit the natural shape of the foot. When the upper 2 is inserted, it is adapted to the curvature of two retaining edges (the left retaining edge 11 and the right retaining edge 12), reducing the feeling of pressure on the foot from edges of the slipper, and making it more comfortable to wear; moreover, the curved surface design can also increase the contact area between the upper 2 and the foot, enhancing comfort and ensuring more stable wearing of the slipper with reduced slippage.

[0042] Preferably, the upper 2 includes a main portion 21, a left side portion 22 and a right side portion 23; the main portion 21 is directly located above the sole 1 and is configured to cover the instep; the left side portion 22 and the right side portion 23 are respectively inserted from the inner sides of the left retaining edge 11 and the right retaining edge 12, pass through the left through hole 111 and the right through hole 121, and are then folded back to be bonded to the outer surface of the upper 2, thereby fastening the upper 2 on the sole 1.

[0043] Further preferably, two ends of the outer surface of the upper 2 are respectively provided with hook-and-loop fasteners 3, and the upper 2 as a whole is made of looped fabric (pile), so as to achieve reliable bonding with the hook sides of the hook-and-loop fasteners 3 at any position, thereby adapting to users with different foot shapes. Of course, the inner side surface (i.e. the side in contact with the foot) of the main portion 21 may also be designed to be made of other more comfortable materials, so as to further improve wearing comfort.

[0044] The described looped fabric (pile) may also be replaced by other materials, as long as a bonding effect can be achieved. FIG. 4 shows a schematic view of the upper 2 in a flat state, the hook-and-loop fasteners 3 at ends of the left side portion 22 and the right side portion 23 and the bonding area of the outer surface of the main portion 21 are located on the same side.

[0045] Further preferably, each of the left side portion 22 and the right side portion 23 has a width smaller than that of the main portion 21, which can ensure that during insertion and bonding, the two side portions do not affect the overall appearance and comfort of the upper 2 due to an excessively large width; moreover, the relatively small width can also reduce the material used and lower cost while maintaining sufficient strength and stability.

[0046] As shown in FIGS. 1 and 2, the left side portion 22 has a length greater than that of the right side portion 23. The right side portion 23 passes through the right through hole 121, and is then folded back to be bonded to the bonding area of the outer surface of the main portion 21 by means of the hook-and-loop fastener 3 at one end of the right side portion; the left side portion 22 passes through the left through hole 111, and is then folded back to be bonded, by means of the hook-and-loop fastener 3 at one end of the left side portion, to a surface bonding area of the right side portion 2 formed by folding the right side portion 23 back, as shown in FIG. 1. This design not only improves wearing comfort, but also provides a more aesthetic appearance, avoiding exposed bonding signs, and making the overall upper look more concise.

[0047] Of course, the left side portion 22 can also have a length smaller than that of the right side portion 23. The left side portion 22 and the right side portion 23 can also be designed to have equal lengths; and in this case, the left side portion 22 passes through the left through hole 111, and is bonded to the left side area of the outer surface of the main portion 21 by means of the hook-and-loop fastener 3 at one end of the left side portion, and the right side portion 23 passes through the right through hole 121, and is bonded to the right side area of the outer surface of the main portion 21 by means of the hook-and-loop fastener 3 at one end of the right side portion.

[0048] In addition, some cartoon patterns may be provided on the outer surface of the left side portion 22, thereby improving the personalization and decoration effect of the slipper, meeting requirements of different users, especially children and adolescent users, as cartoon patterns can improve the fun and attractiveness of the slipper.

[0049] The left retaining edge 11 and the right retaining edge 12 on two sides of the sole 1 extend rearwards, and are connected together to form a continuous surrounding edge. The extension portion has a height lower than that of the left retaining edge 11 and the right retaining edge 12. Moreover, the inner side surface of the surrounding edge is a curved surface adapted to the curvature of the heel, preventing the slipper from falling off during walking, thereby providing more comfortable wearing.

Embodiment II

[0050] Embodiment II is substantially the same as embodiment I, and the difference lies in that in embodiment II, there are two left through holes 111 and two right through holes 121. Specifically, as shown in FIG. 5, the left retaining edge 11 is provided with two left through holes 111 in the width direction of the sole 1, and the right retaining edge 12 is provided with two right through holes 121 in the width direction of the sole 1.

[0051] The upper 2 includes a first upper and a second upper, two ends of the first upper respectively pass through one left through hole 111 and one right through hole 121, two ends of the second upper respectively pass through the other right through hole 121 and the other right through hole 121, and the first upper and the second upper are arranged in a crossed or parallel manner, and form a detachable connection with respective two ends.

[0052] In other embodiments, the number of left through holes 111 and the number of right through holes 121 are not limited, and may be set according to actual requirements.

Embodiment III

[0053] Embodiment III is substantially the same as embodiment I, and the difference lies in the distinct bonding positions of the hook-and-loop fasteners 3; in this embodiment, as shown in FIGS. 6 and 7, the upper 2 as a whole is made of looped fabric, and the left side portion 22 has a length greater than that of the right side portion 23; a plurality of first hook-and-loop fasteners are arranged at intervals on the outer surface of the main portion 21, and are configured to be bonded to the outer surface of the right side portion 23; a second hook-and-loop fastener is provided at one end of the outer surface of the left side portion 22, and is configured to be bonded to the surface bonding area of the right side portion 23 formed by folding the right side portion 23 back.

[0054] The right side portion 23 passes through the right through hole 121, and is then folded back to be bonded to a first hook-and-loop fastener on the outer surface of the main portion 21; the left side portion 22 passes through the left through hole 111, and is then folded back to be bonded, by means of the second hook-and-loop fastener at the end of the left side portion, to the corresponding bonding area on the surface of the right side portion 23 formed by folding the right side portion 23 back, thereby completing installation and fastening of the upper 2 on the sole 1.

[0055] In conclusion, the present disclosure has at least the following advantages: [0056] 1. The overall structure is simple, and the assembly and disassembly are convenient, allowing a user to replace different uppers according to requirements so as to meet personalized requirements; moreover, a user is allowed to freely adjust the bonding positions of the hook-and-loop fasteners at two ends of the upper, so as to fit his or her foot shape or improve wearing comfort. [0057] 2. When the slipper is worn, the bonding surface of the upper is located externally, which improves the foot comfort, provides visible and easily detachable design, with a tear-off point visible at a glance, allowing for quick replacement and easy cleaning of the upper.
