Benefits of technology

[0009]A shoe vamp in accordance with the present invention comprises a front end, a rear end, a longitudinal axis, a transverse axis and an opening. The longitudinal axis extends longitudinally from the rear end to the front end. The transverse axis is perpendicularly to the longitudinal axis. The opening is defined through the shoe vamp and has an inclined front edge inclined to the longitudinal axis and the transverse axis and has an inside end and an outside end being closer to the front end of the shoe vamp when compared to the inside end. the shoe vamp with the inclined front edge of the opening corresponds entirely to the shape of the instep of a foot to prevent the foot from rotating or moving on the shoe. Therefore, the shoe vamp effectively prevents varus or talipes valgus.

Problems solved by technology

However, the vamp concerning the foot health is ignored by designers.
However, no outstanding improvement is achieved.

first embodiment

[0017]With reference to FIG. 1, a shoe vamp in accordance with the present invention is mounted on a sole of one of a pair of shoes. The shoes are made without shoelaces and may be leather shoes or boots.

[0018]The shoe vamp comprises a front end, a rear end, a longitudinal axis (A), a transverse axis (L) and an opening (20).

[0019]The front end corresponds to toes of a foot.

[0020]The rear end corresponds to a heel of the foot.

[0021]The longitudinal axis (A) extends longitudinally from the rear end to the front end.

[0022]The transversely axis (L) is perpendicularly to the longitudinal axis (A).

[0023]The opening (20) is defined through the shoe vamp, allows the foot to extend through the opening (20) into the shoe and has an inclined front edge (11).

[0024]The inclined front edge (11) is inclined relative to the longitudinal axis (A) and the transverse axis (L), may have a first acute included angle (θ) between the inclined front edge (11) and the transverse axis (L) in an extent from 5...

second embodiment

[0025]With reference to FIG. 2, the shoe vamp in accordance with the present invention is mounted on a sole of one of a pair of shoes. The shoes are made with shoelaces and may be gym shoes, walking shoes or running shoes. The shoe vamp comprises a front end, a rear end, a longitudinal axis (A), a transverse axis (L), an inside flap (15), an outside flap (16), a tongue (17) and an opening (20A).

[0026]The inside flap (15) has a rear end.

[0027]The outside flap (16) is shorter than the inside flap (15) and has a rear end closer to the front end of the shoe vamp when compared to the rear end of the inside flap (15).

[0028]The tongue (17) is formed between the inside flap (15) and the outside flap (16) and has a rear edge that is inclined.

[0029]The opening (20A) has an inclined front edge (11A). The inclined front edge (11A) is similar to that of the first embodiment and is formed on the rear ends of the inside flap (15) and the outside flap (16) to make the rear end of the outside flap (...

Abstract

A shoe vamp has a front end, a rear end, a longitudinal axis, a transverse axis and an opening. The longitudinal axis extends longitudinally from the rear end to the front end. The transverse axis is perpendicularly to the longitudinal axis. The opening is defined through the shoe vamp and has an inclined front edge inclined to the longitudinal axis and the transverse axis and has an inside end and an outside end being closer to the front end of the shoe vamp when compared to the inside end. The shoe vamp with the inclined front edge of the opening corresponds entirely to the shape of the instep of a foot to prevent the foot from rotating or moving on the shoe. Therefore, the shoe vamp effectively prevents varus or talipes valgus.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a shoe vamp, and more particularly to a shoe vamp that is mounted on a shoe and has an opening including an inclined front edge to prevent a foot wearing the shoe from rotating or moving relative to the shoe.[0003]2. Description of Related Art[0004]Shoes basically have a sole and a vamp. The sole has been highly valued and developed for comfort and durability. However, the vamp concerning the foot health is ignored by designers.[0005]With reference FIGS. 5 and 6, a conventional shoe has a front end, a rear end, an axis, a vamp (90) and a sole. The vamp (90) has an opening, a front outer side (91) and a rear inner side (92). The axis extends longitudinally from the rear end to the front end. The opening has a front edge. The front edge of the vamp (90) contacts the instep of a foot when the foot wears the shoe and is designed to perpendicularly to the axis without considering ergonomics. ...
