A shoe insert includes a generally planar body having a perimeter defining a foot-shaped area on an upper side of the body, the foot-shaped area including first and second toe areas and a heel area configured respectively for placement of a first toe, a second toe, and a heel of a user. The upper side defines a channel extending along an axis passing through a space between the first and second toe areas and the heel area. A linear member may be placed in the channel to protrude from an upper surface of the body. When a user uses the insert, the user's foot may sense the channel (or linear member, if present) and activate mechano-receptors on the bottom of the foot along the channel, which, in-turn, may train the foot to extend in a predetermined position relative to the linear member to improve balance.
1. A shoe insert comprising:
a body having a perimeter defining a foot-shaped area on an upper side of the body, the foot-shaped area including a first and second toe area and a heel area configured respectively for placement of a first and second toe and a heel of a user, the upper side defining only two sensory feedback structures including a first sensory feedback structure extending along a first axis from a space between the first and second toe areas and the heel area, and defining a second sensory feedback structure located laterally of the first sensory feedback structure,
wherein the first sensory feedback structure includes a first channel, and the second sensory feedback structure includes a second channel,
wherein the second channel extends along a second axis that intersects with the first axis,
wherein the first and second channels extend distally from a midsole area, and
wherein the first sensory feedback structure includes a first elongated member disposed in the first channel and protruding above a surface of the upper side of the body, and the second feedback structure includes a second elongated member disposed in the second channel and protruding above a surface of the upper side of the body.
2. The shoe insert according to claim 1 , wherein:
the second channel extends at an angle between 1 and 15 degrees relative to the first channel.
3. The shoe insert according to claim 1 , wherein:
the first channel extends from the space between the first and second toe areas to the midsole area, and
the second channel extends from a third toe area to the midsole area.
4. The shoe insert according to claim 1 , wherein:
the first elongated member and the second elongated member are resilient and compressible.
5. The shoe insert according to claim 1 , wherein:
at least one of the first and second elongated members is removably coupled to the body.
6. A shoe insert kit comprising:
a body having a perimeter defining a foot-shaped area on an upper side of the body, the foot-shaped area including a first and second toe area and a heel area configured respectively for placement of a first and second toe and a heel of a user, the upper side defining only two sensory feedback structures including a first sensory feedback structure extending along a first axis from a space between the first and second toe areas and the heel area, and defining a second sensory feedback structure located laterally of the first sensory feedback structure,
wherein the first sensory feedback structure includes a first channel, and the second sensory feedback structure includes a second channel,
wherein the second channel extends along a second axis that intersects with the first axis,
wherein the first and second channels extend distally from a midsole area; and
a first sensory feedback structure including a first elongated member disposable in the first channel and protruding above a surface of the upper side of the body; and
a second feedback structure including a second elongated member disposable in the second channel and protruding above a surface of the upper side of the body.
7. The shoe insert kit according to claim 6 , wherein:
the first channel extends along a gravitational stress line extending along an axis from a space between a first toe area and a second toe area to the heel area.
8. The shoe insert kit according to claim 7 , wherein:
the body defines a hole in the heel area, and the kit further comprises at least one heel insert configured for insertion in the hole.
9. The shoe insert kit according to claim 6 , wherein:
the kit includes a symmetrical pair of bodies for left and right feet of a user.
