## Abstract

A functional shoe insole includes: a body part located inside a shoe, and configured to, when the shoe is worn by a user, come into direct contact with a sole of a foot of the user and distribute a load applied to the foot; an arch stimulation member coupled to the body part at a predetermined position, and configured to stimulate an arch portion of the sole of the foot of the user; and a heel stimulation member coupled to the body part at a predetermined position, and configured to stimulate a heel portion of the sole of the foot of the user. The arch stimulation member includes a first arch acupressure module. The heel stimulation member includes a first heel acupressure module.

wherein the fourth frame is formed to become narrower in width in a direction from one of the opposite edges of the third frame to a center of a distance between the opposite edges of the third frame and then to become wider in a direction from the center of the distance to a remaining one of the opposite edges of the third frame, and at least one cushion protrusion is provided on a top surface of the fourth frame.

### Claim 2 (depends on 1)

The functional shoe insole of claim 1, wherein the arch stimulation member further includes a second arch acupressure module that is coupled to the first arch acupressure module and supports the first arch acupressure module, and
wherein the second arch acupressure module is formed in a shape corresponding to a bottom surface of the second frame of the first arch acupressure module, and, when the second arch acupressure module is coupled to the first arch acupressure module, the second arch acupressure module is contained in the arch-shaped space formed by the first arch acupressure module and is positioned under the second frame of the first arch acupressure module, thereby forming another arch-shaped space.

### Claim 3 (depends on 1)

The functional shoe insole of claim 1, wherein the arch stimulation member further includes a second arch acupressure module that is coupled to the first arch acupressure module and changes a height of the upward curve on the top surface of the body part,
wherein the second arch acupressure module includes a fifth frame provided with rectangular edges having a predetermined thickness, and a sixth frame coupled in a form rising upward from opposite edges of the fifth frame toward a center of the fifth frame and configured to form an arch-shaped space,
wherein the sixth frame includes a circular unit disposed at a center of the sixth frame, and a pair of coupling units configured to connect the circular unit and the edges of the fifth frame, and
wherein the coupling units are formed to become narrower in width in directions from the edges of the fifth frame to the circular unit.

### Claim 4 (depends on 3)

The functional shoe insole of claim 3, wherein the first arch acupressure module and the second arch acupressure module are made of a polyester-based synthetic resin material, a synthetic rubber material of baritone rubber, or an elastic material of elastic fiber, and are elastically deformable according to an elastic modulus, which is a designed ratio of stress to strain.

### Claim 5 (depends on 2)
