Benefits of technology

"The present invention provides a boot that can be adjusted to fit different sizes of feet. The boot has a shell with an open top end and an instep part, an opening extending from the upper portion to the foot portion, and a pair of margins. A closure member is attached to the margins to close the opening. A liner is secured to the inner surface of the shell on both sides of the opening, with its outer surface facing the margins and the opening. A retaining unit is attached to the liner. An adjustment pad is attached to the retaining unit to adjust the fitting of the shell. This design allows for easy adjustment to fit different sizes of feet, making it more comfortable and flexible for users."

Problems solved by technology

However, since such a boot is made by using a standard last, it is unable to fit properly different users' feet.
Furthermore, unlike a shoe lacing, the zipper 1 is not adjustable to tighten or loosen the boot to conform to the size of the wearer's foot.
Therefore, if the user with a thin foot puts on the boot, the boot would become loose, especially at the instep part of the foot.
However, the need to provide such a lot of lasts not only increases the manufacturing cost but also complicates the process of producing boots.
In addition, since shoe sellers must stock various sizes of boots, they may be burdened with the inventory of boots.

first embodiment

[0023] Referring to FIGS. 2 and 3, the present invention includes a boot 2 which has an outsole 10 connected to a shell 20. The shell 20 includes an upper portion 21 connected to a foot portion 22, an instep part 25 at the juncture of the upper portion 21 and the foot portion 22, and an opening 23 which extends from the instep part 25 to an open top end of the upper portion 21. The opening 23 is defined by an opposed pair of margins 24 of the shell 20. A closure member, such as a zipper 60, is attached to the margins 24 to close the opening 23.

[0024] A liner 30 has two opposite ends 31 which are attached to the inner surface of the shell 20 on two sides of the opening 23 so that the liner 30 underlies the opening 23 and the margins 24, and has an outer surface facing the opening 23 and the margins 24. The outer surface of the liner 30 and the inner side of the margins 24 cooperatively define a space 26 (see FIG. 4). The liner 30 is made of a flexible material, preferably a stretchab...

third embodiment

[0030] Referring to FIGS. 7, 8 and 9, the present invention differs from the first embodiment as follows: This embodiment includes a retaining unit which is formed as a stud 43 to retain an adjustment pad 50′, and an closure member which is configured to include two complementary velcro straps 61 and 62. The adjustment pad 50′ in this embodiment is similar to that of the second embodiment and is pivotable about the stud 43 so as to turn the thin or thick section 511 or 512 thereof downward to a position close to the instep part 25. The positions of the thin and thick sections 511 and 512 are therefore interchangeable by turning the adjustment pad 50′ about the stud 43. When the wearer puts on the boot and interengages the velcro straps 61 and 62, the opening 23 is closed so that the space between the liner 30 and the margins 24 is stuffed. This increases the tightness of the boot at the instep part 25.

[0031] Referring to FIGS. 10 and 11, a fourth embodiment of the present invention ...

Abstract

A boot includes a shell having a foot portion, an upper portion with an open top end, an opening extending from the top end to the foot portion, and an opposed pair of margins defining the opening. A liner has two opposite ends secured to an inner surface of the shell on two sides of the opening so that the liner has an outer surface facing the margins and the opening. A retaining unit is attached to the liner, and an adjustment pad is mounted on the retaining unit so as to adjust the fitting of the shell. The adjustment pad extends from the upper portion to the foot portion. Preferably, the adjustment pad has a thin section and a thick section which are placed selectively within the foot portion to vary the fitting of the shell.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a boot, more particularly to a boot which has an adjustment compressible pad to adjust the fitting of the boot. [0003] 2. Description of the Related Art [0004] Referring to FIG. 1, a typical pull-on type shoe or boot is provided with a zipper 1 so that the shoe or boot can be put on or off easily. However, since such a boot is made by using a standard last, it is unable to fit properly different users' feet. Furthermore, unlike a shoe lacing, the zipper 1 is not adjustable to tighten or loosen the boot to conform to the size of the wearer's foot. Therefore, if the user with a thin foot puts on the boot, the boot would become loose, especially at the instep part of the foot. [0005] In order to alleviate the aforesaid drawbacks, manufacturers utilize several sets of lasts with different dimensions for the production of different sizes of boots so as to conform to various sizes of feet. However...
