DETAILED DESCRIPTION OF THE. INVENTION
A shoe with a flexible upper according to a first embodiment of the present invention is shown in FIGS. 1 through 3 of the drawings and generally includes an outsole 1, a main body 2, and a first elastic lace 3. The outsole 1 has a bottom surface (stampede plane) 11, which is used to contact the ground, and a top surface (assembly plane) 12 opposite to the bottom surface 11, and defines a first groove 13 extending across the top surface 12 in a transverse direction to reach two opposite lateral sides of the outsole 1. Specifically, the material of the outsole I can be a plastic made from Ethylene-vinyl Acetate (EVA), and can be formed to have various sizes according to a left foot or a right foot of human. In one embodiment, the bottom surface 11 can be provided with an anti-slip pattern (not shown) made of rubber. The top surface 12 is concave slightly. Generally, the top surface 12 of the outsole 1 has a rear section 121, a
4 middle section 122, and a front section 123. The first groove 13 is generally located at the middle section 122 of the top surface 12 of the outsole 1. The main body 2 includes an insole 21 and a flexible upper 22. The insole 21, which has a shape corresponding to the top surface 12 of the outsole 1, is attached to the top surface 12 of the outsole 1.
The flexible upper 22 is formed of a four-way stretch fabric that can be deformed to some extent to conform with the shape of one foot of a user. The flexible upper 22 is attached to a peripheral edge of the insole 21, so that the insole 21 and the flexible upper 22 defines a receiving space 23, wherein a top opening or throat 24 is defined by the flexible tipper 22 and communicates with the receiving space 23 to allow one foot of a user to be accommodated in the receiving space 23. The first elastic lace 3 can be routed to extend through the first groove 13 and loop around the flexible upper 22 of the main body 2 to limit the extent of deformation of the flexible upper 22.
In use, one foot of a user can be inserted through the top opening 24 to enter the receiving space 23. The flexible upper 22 can be deformed to some extent by the foot and can be in contact with the outer surface of the foot. The first elastic lace 3 can limit the extent of the deformation of the flexible upper 22 and can be snugly fitted around the user's foot. As such, the shoe can be comfortably worn by the user, and thus can solve the unfit problems of conventional shoes due to insufficient elasticity of the mesh fabrics making the uppers of the shoes. =
More specifically, as shown in FIGS. 1 through 5, the rear section 121, the middle section 122, and the front section 123 of the top surface 12 of the outsole 1 are located generally corresponding to the heel portion, the arch portion, and the toe portion of a human foot, respectively. The flexible upper 22 has a rear portion 221 corresponding to the rear section 121, a middle portion 222 corresponding to the middle section 122, and a front portion 223 corresponding to the front section 123 (see FIG 3). The first groove 13 has a first end 131 and a second end 132 respectively at the
The flexible upper 22 is formed of a four-way stretch fabric that can be deformed to some extent to conform with the shape of one foot of a user. The flexible upper 22 is attached to a peripheral edge of the insole 21, so that the insole 21 and the flexible upper 22 defines a receiving space 23, wherein a top opening or throat 24 is defined by the flexible tipper 22 and communicates with the receiving space 23 to allow one foot of a user to be accommodated in the receiving space 23. The first elastic lace 3 can be routed to extend through the first groove 13 and loop around the flexible upper 22 of the main body 2 to limit the extent of deformation of the flexible upper 22.
In use, one foot of a user can be inserted through the top opening 24 to enter the receiving space 23. The flexible upper 22 can be deformed to some extent by the foot and can be in contact with the outer surface of the foot. The first elastic lace 3 can limit the extent of the deformation of the flexible upper 22 and can be snugly fitted around the user's foot. As such, the shoe can be comfortably worn by the user, and thus can solve the unfit problems of conventional shoes due to insufficient elasticity of the mesh fabrics making the uppers of the shoes. =
More specifically, as shown in FIGS. 1 through 5, the rear section 121, the middle section 122, and the front section 123 of the top surface 12 of the outsole 1 are located generally corresponding to the heel portion, the arch portion, and the toe portion of a human foot, respectively. The flexible upper 22 has a rear portion 221 corresponding to the rear section 121, a middle portion 222 corresponding to the middle section 122, and a front portion 223 corresponding to the front section 123 (see FIG 3). The first groove 13 has a first end 131 and a second end 132 respectively at the
5 two opposite lateral sides of the outsole I. The top surface 12 of the outsole 1 further defines a second groove 14 and a third groove 15.
