BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an insole, and especially to a stabilizing insole that can be mounted in one or more positions in a shoe to provide increased stability for a person wearing the shoe so the person is less likely to lose their balance, fall or turn their ankle.
2. Description of the Related Art
With the rise and increased interest in human engineering in society, shoes are a subject of human engineering as seen by air cushions in conventional soft-shoes and shapes of upper surfaces of soles to conform to people's feet. However, legs of almost every person are at least a slightly different length. Even slight differences in leg length can cause a person's joints to hurt especially in modern soft-shoes and conformal shoes. Often, a doctor attempts to correct bad posture with corrective shoes. However, the effect of wearing corrective shoes in correcting posture may not be obvious, and the price of corrective shoes is high.
- SUMMARY OF THE INVENTION
To overcome the shortcomings, the present invention provides a stabilizing insole and a method for using the stabilizing insole so people can wear comfortable shoes, and the stabilizing insole is inexpensive.
The objective of the present invention is to provide a stabilizing insole to make a shoe comfortable and keep a person from losing his or her balance and possibly falling or turning his or her ankle.
To achieve the foregoing objective, a stabilizing insole in accordance with the present invention has at least one pad that is mounted on an upper surface of a shoe sole. Each pad has an edge, at least one first surface and a second surface. Each first surface has a support surface. The support surface is formed on the first surface and is harder than the first surface. The second surface extends from the first surface and may slope down toward the edge of the pad. The at least one pad concentrates force applied by a person's foot at natural balance points so the user does not twist his or her ankle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 7 is a perspective view of a slipper having the pads in FIGS. 1 and 4.
With reference to FIGS. 1 to 5, a stabilizing insole in accordance with the present invention comprises at least one pad (10, 10 a). The at least one pad (10, 10 a) may be a heel pad (10), a ball and toe pad (10 a) or both and is mounted on an upper surface of a shoe sole, and each pad (10, 10 a) has an edge, at least one first surface (11, 11 a, 11 b) and a second surface (12, 12 a), With further reference to FIG. 6, the heel pad (10) is oval and has a semi-oval first surface (11). The ball and toe pad (10 a) is tongue shaped, corresponds uniquely to a right or left foot and has a front first surface (11 a) and a rear first surface (11 b). The front first surface (11 a) corresponds to the ball and toe pad (10 a) and has a concave rear edge. The rear first surface (11 b) is formed on and protrudes from the concave rear edge. Each first surface (11, 11 a, 11 b) has a support surface (110, 110 a, 110 b). The support surface (110, 110 a, 110 b) is formed on the first surface (11, 11 a, 11 b) to support a corresponding ball and heel on a person's foot and is harder and may be slightly higher than the corresponding first surface (11, 11 a, 11 b). The support surface (110 b) on the rear first surface (11 b) protrudes up from the rear first surface (11 b) to massage the yongquan, a Chinese pressure point between the first and second metatarsal near the arch to stimulate and maintain health of the kidneys. The support surface (110 b) is regarded as a fulcrum to support the heel and the ball and toe on the person's foot to massage the yongquan. The second surface (12, 12 a) abuts the at least one first surface (11, 11 a, 11 b) and slants away from the at least one first surface (11, 11 a, 11 b) to the edge of the pad (10, 10 a).
The method for using the stabilizing insole in accordance wit the present invention comprises:
providing at least one pad (10, 10 a); and
mounting the at least one pad (10, 10 a) in a shoe corresponding to a user's heel or ball of a foot.
With further reference to FIG. 7, the at least one pad (10, 10 a) may be formed on a pair of slippers and positioned to correspond to a user's heel or ball of the foot.
The at least one pad (10, 10 a) supports a user's feet to decrease the area of force and form three support points so the user does not twist his or her ankle.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
