This application claims priority to Taiwanese Patent Application No. 108122823, filed on Jun. 28, 2019.
The disclosure relates to a shoe, more particularly to a moisture-permeable waterproof shoe that can be changed to different styles.
Referring to
Therefore, an object of the present disclosure is to provide a multi-style moisture-permeable waterproof shoe that is capable of alleviating at least one of the drawbacks of the prior art.
Accordingly, a multi-style moisture-permeable waterproof shoe of this disclosure includes an outer shoe body unit defining an insertion space that has an open top end and a closed bottom end, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space of the outer shoe body unit. Each sock-like inner shoe body unit includes a moisture-permeable waterproof shoe-like inner sleeve, an outer sock body and an inner adhesive layer. The moisture-permeable waterproof shoe-like inner sleeve defines a foot space that has an open top end and a closed bottom end and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the moisture-permeable waterproof shoe-like inner sleeve. The inner adhesive layer is adhered between an outer surface of the moisture-permeable waterproof shoe-like inner sleeve and an inner surface of the sock body portion.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
Before the present disclosure is described in greater detail with reference to the accompanying embodiments, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.

The cut piece 11 has a main body 13, and two wing portions 14 symmetrically disposed on two opposite sides of the main body 13 and integrally connected as one piece with the main body 13. The main body 13 has a front convex portion 131 and a rear concave portion 132 opposite to the front convex portion 131. Each of the front convex portion 131 and the rear concave portion 132 has two opposite ends.
Each wing portion 14 includes a wing lateral edge 141 spaced apart from the main body 13 and having a front end and a rear end, a front curved edge 142 connected between the front end of the wing lateral edge 141 and a corresponding one of the two opposite ends of the front convex portion 131, and a rear mating edge 143 connected between the rear end of the wing lateral edge 141 and a corresponding one of the two opposite ends of the rear concave portion 132.
In this embodiment, the front curved edges 142 of the wing portions 14 are connected by sewing to a periphery of the front convex portion 131 of the main body 13, the wing lateral edges 141 of the wing portions 14 are connected by sewing to each other, and the rear mating edges 143 of the wing portions 14 are also connected by sewing to each other, thereby forming the shoe-like inner sleeve 10. The front curved edge 142 of each wing portion 14 has an arc length substantially equal to one half of an arc length of the front convex portion 131.
It should be noted herein that, in other variations of this embodiment, the front curved edge 142 of each wing portion 14 may be ultrasonically welded to the periphery of the front convex portion 131 of the main body 13, the wing lateral edges 141 of the wing portions 14 may be ultrasonically welded to each other, and the rear mating edges 143 of the wing portions 14 may be ultrasonically welded to each other.
The waterproof unit 12 is fixedly connected to the moisture-permeable waterproof layer 114 (see
The waterproof unit 12 includes a first waterproof strip 121 and two second waterproof strips 122. The first waterproof strip 121 extends from the front end to the rear end of the shoe-like inner sleeve 10, as shown in
Each second waterproof strip 122 is fixedly connected to and covers the outer surface 114 of the shoe-like inner sleeve 10 at a position corresponding to the junction of the front curved edge 142 of each wing portion 14 and the periphery of the front convex portion 131, as shown in

(9) heating the assembly of the outer sock body 20 and the moisture-permeable waterproof shoe-like inner sleeve 10 to more than 80° C. for 2 to 10 minutes, so that the outer sock body 20 and the shoe-like inner sleeve 10 can be fixedly adhered to each other;
(10) removing the shoe last from the assembly of the outer sock body 20 and the moisture-permeable waterproof shoe-like inner sleeve 10; and
(11) folding the cuff portion 22 of the outer sock body 20 inwardly and downwardly over the top peripheral portion of the shoe-like inner sleeve 10 toward the foot space 15 of the shoe-like inner sleeve 10, and sewing the cuff portion 22 to the lining layer 111 of the moisture-permeable waterproof shoe-like inner sleeve 10.
Referring back to
From the aforesaid description, the advantages of this disclosure can be summarized as follows:
(1) In comparison with the prior art, the sock-like inner shoe body units (100a, 100b) of this disclosure are designed to be inserted removably and selectively into the insertion space 45 of the outer shoe body unit 200 so as to form a moisture-permeable waterproof shoe 300 that can match his/her different style of outfit. Hence, the moisture-permeable waterproof shoe 300 of this disclosure is flexible to use, so that there is no need for the user to change between different shoes. Further, with each sock-like inner shoe body unit (100a, 100b) cooperating with the outer shoe body unit 200, the moisture-permeable waterproof shoe 300 can present a three-dimensional appearance.
(2) In comparison with the prior art, the sock-like inner shoe body units (100a, 100b) of this disclosure can use the stiffness of the upright velvet layer 113 to support the three-dimensional shape thereof, so that when the shoe-like inner sleeve 10 is inserted into the outer sock body 20, the outer sock body 20 will not collapse, thereby facilitating quick insertion of the user's foot into the foot space 15 of the shoe-like inner sleeve 10. Thus, convenience and comfort in wearing the moisture-permeable waterproof shoe 300 of this disclosure can be improved.
(3) Since the elastic cuff portion 22 of the outer sock body 20 is folded inwardly and downwardly over the top peripheral portion of the shoe-like inner sleeve 10 toward the foot space 15 of the shoe-like inner sleeve 10 and is sewn to the lining layer 111 of the shoe-like inner sleeve 10, the cuff portion 22 can cover the top peripheral portion of the shoe-like inner sleeve 10. By using the cuff portion 22, the number of components required for sewing in each of the sock-like inner shoe body units (100a, 100b) can be reduced, thereby lowering the manufacturing costs. Moreover, each of the sock-like inner shoe body units (100a, 100b) can present an integral appearance, thereby improving the overall appearance of the moisture-permeable waterproof shoe 300.
(4) The moisture-permeable waterproof shoe-like inner sleeve 10 of each sock-like inner shoe body unit (100a, 100b) of this disclosure uses the cooperation of the moisture-permeable waterproof layer 114 with the first waterproof strip 121 and the second waterproof strips 122 to effectively prevent penetration of water into an interior of the moisture-permeable waterproof shoe-like inner sleeve 10, thereby providing a good waterproof effect to the user's foot. Further, the moisture-permeable waterproof layer 114 can permit the moisture to discharge outwardly to keep the user's foot dry.
(5) The upright velvet layer 113 of the moisture-permeable waterproof shoe-like inner sleeve 10 of each sock-like inner shoe body unit (100a, 100b) of this disclosure has good elasticity to facilitate smooth insertion of the user's foot into the shoe-like inner sleeve 10. Further, the upright velvet layer 113 also has good air permeability to effectively enhance the comfort of wearing the moisture-permeable waterproof shoe 300. Moreover, the upright velvet layer 113 is woven between the lining layer 111 and the outer fabric layer 112 to form an integral structure, so that the upright velvet layer 113 cannot be easily separated therefrom.

Referring to
Apart from achieving the same effect as that of the first embodiment, the second embodiment can further permit the user to walk around indoor through the sock-like inner shoe body unit (100a″, 100b″) after the moisture-permeable waterproof shoe 300 is removed.
Therefore, the object of this disclosure can indeed be achieved.
