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 overcoming the aforementioned drawbacks of the prior art.

FIG. 2 is a schematic view of an insole bottom surface of a preferred embodiment of this disclosure.
DESCRIPTION OF THE EMBODIMENTS
[0014] 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.
[0015] 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 the first placing area 11.
[0016] 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.
[0017] 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° to 80°, 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 1 and the other end coupled to an end of the third straight line 122 to form an included angle of 70° to 80°, and the fourth straight line 123 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 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 1 13, 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.
[0018] 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.
[0019] 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.
[0020] 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 more ergonomic after using the insole 1, so as to achieve both practical and comfortable functions.
