ABSTRACT:
A method of making an insole having a heel positioner and an arch support, in which the positioning support for the heel is made in situ, in one discrete section of the foot support, and the arch support is then made, in situ, in a second discrete section.
The first discrete section is made at the heel portion of the foot, in a manner so as to stabilize the plantar surface of the heel section of the foot under the cancaneous bone. This is for the purpose of eliminating, reducing or minimizing the rotation forces applied to the heel section of the foot by the weight of the body, which would normally tend to produce a pes valgus (outward bending) or a pes varus (inward bending) condition, as well as stabilizing the anterior - posterior position of the leg in its function of bearing body weight.
Once the heel stabilizer section has been formed, in situ, a discrete arch support section is then provided, in situ, for the arch portions of the foot so that the body weight will not tend to place strain upon the inner structures of the foot (bone joints, tendons, muscles, and related tissues), in the arch sections which connect the heel to the second part of the foot that support the body weight (i.e., the ball of the foot).
