FIG.1

INSOLE CAPABLE OF ASSISTING CORRECTIONS OF VARIOUS FOOT PROBLEMS BACKGROUND BACKGROUND Technical Field

[00011 The present disclosure generally relates to the field of insoles. More

particularly, the present disclosure relates to an insole capable of assisting corrections of

various foot problems.

Description of Related Art

[0002] Humans are prone to become fatigued or injured under the pressure of standing

or walking repeatedly for a long time. Particularly in the case of wearing a pair of poor

shoes, one may sprain the ankle ligaments easily. Therefore, various insoles are

developed to provide proper softness and comfort for users while wearing shoes. Most

conventional insoles are pads in a shape corresponding to the shape of a user's foot and

manufactured by a flexible material foaming technology, and these insoles provide a basic

shock absorbing function while walking or standing and have the features of high softness

and timely resilience.

[0003] However, there are many structural abnormalities in human feet, such as flat

feet, outward splayed feet, inward splayed feet, splayed toes, etc., and the conventional

insole generally provides no solution or corresponding protection structure to these

problems, so that users having the aforementioned troubles cannot soothe or improve the

pain or discomfort of their feet.

[0004] Therefore, the inventor of the present disclosure based on years of experience

in the related industry to conduct extensive research and experiment, and finally

developed an insole capable of assisting corrections of various foot problems in hope of

-1- overcoming the aforementioned drawbacks of the prior art. 18 Feb 2025 2019246917 18 Feb 2025

[0016] Reference will now be made in detail to the present embodiments of the

disclosure, examples of which are illustrated in the accompanying drawings. Wherever

possible, the same reference numbers are used in the drawings and the description to refer

to the same or like parts.

[00171 With reference to FIGS. 1 and 2 for schematic views of an insole and an insole

bottom surface in accordance with a preferred embodiment of the present disclosure

respectively, the present disclosure discloses an insole capable of assisting corrections of

various foot problems 1, characterized in that the insole 1 comprises a first placing area

11, a second placing area 12 and a third placing area 13 defined on an insole bottom and

provided for attaching a pad (not shown in the figure) to improve inward/outward splayed

feet and uneven leg length, and the first placing area 11 and the second placing area 12

are disposed on left and right sides of a bottom surface of the insole 1, and the third

placing area 13 is disposed at a position of the bottom of the insole 1 corresponding to a

user's heel, and the position of the second placing area 12 is higher than the position of

-4- the first placing area 11.

[0018] In an application, the user may request a doctor to determine the thickness of

the attached pad and the position where the pad is attached to the first placing area 11, the

second placing area 12, the third placing area 13, or any combination of the above

according to the conditions of the inward/outward splayed feet or uneven leg length.

The advantage resides on that the user does not have to worry about an insufficient

thickness of the pad that may cause discomfort to the user when the user is walking or

standing, and the doctor can design the first placing area 11, the second placing area 12

and the third placing area 13 on the insole 1 without the need of worrying about the

position to where the pad should be attached to provide the corrective effect while making

the patient feel comfortable.

[0019] In addition, the position and size of the first placing area 11 and the second

placing area 12 are well designed to meet the ergonomic requirements. In this design,

the first placing area 11 has a boundary comprised of a first arc 111, a first straight line

112, a second straight line 113 and an edge of the insole 1, and the first arc 111 has an

end coupled to the edge of the insole 1 and the other end coupled to an end of the first

straight line 112 to form an included angle of 70° to800, and the second straight line 113

has an end coupled to the edge of the insole 1 to form an included angle of 85° to 90° and

the other end coupled to the other end of the first straight line 112 to form an included

angle of approximately 60°. In addition, the second placing area 12 has a boundary

comprised of a second arc 121, a third straight line 122, a fourth straight line 123 and an

edge of the insole 1, and the second arc 121 has an end coupled to the edge of the insole

insole 1 to form an included angle of 85° to 90° and the other end coupled to the other

end of the third straight line 122 to form an included angle of 60° to 65. In addition,

the length of the fourth straight line 123 is slightly greater than the length of the second

straight line 113, so that the relative position and size of the first placing area 11 and the

second placing area 12 can be shown clearly. After the pad is attached to a placing area

of such position and size the ergonomic design of the insole can improve the

comfortability of the user and the practicality of the insole.

[0020] In this embodiment, the third placing area 13 is comprised of a plurality of grid

areas 131, and each grid area 131 is provided for placing a pad, so that the attachable

areas can be distinguished to allow a doctor to determine whether or not it is necessary to

attach the pad completely onto the grid areas 131 or it just needs to attach the pad to one

or two grid areas 131, so as to improve the applicability.

[0021] To improve the overall supportability of the insole 1 and consider the patient

with high arched feet, an arc wall 14 protrudes and extends from the second half edge of

the top of the insole 1, and a recess 15 is formed at the second half of the top of the insole

1 corresponding to the arc wall 14, and the height of the arc wall 14 at the portion

corresponding to the user's arch position is greater than the height of the remaining

portions of the arc wall 14, and such feature improves the supportability of the user's arch,

and the wrapping feeling of the heel situated at the recess 15 gives a more comfortable

feeling to the user and further improves the practicality of the present disclosure.

[00221 In summation of the description above, the insole 1 of the present disclosure

makes use of the specially designed position and size of the first placing area 11, the

second placing area 12 and the third placing area 13 for attaching the pads to correct a

patient's foot deformity problem, while making the patient's walking or standing posture
