This is heated while in a shoe, and formed by the foot, while still hot, to conform to contours of the foot. Specific locations therein may be further formed to accommodate for excrescencies, by localized heating, manual deformation, to provide excrescency accommodating concavoconvex features on the insole, the convex portion of which is trimmed flush with the remainder of the insole, which is then later reinserted in the shoe.,下面是Adjustable insole and method专利的具体信息内容。

1. A method of fitting an insole in a shoe and comprising the steps of: placing in a shoe a flexible insole member; heating said member to a temperature sufficient to cause said member to lose at least some of its resiliency; placing a foot in the shoe before said member has regained its resiliency; and taking steps with the foot in the shoe until the member has regained its resiliency.
2. The method of claim 1 wherein: the step of heating said member includes the step of placing a heat gun directly into the shoe and blowing hot air from the heat gun into the shoe.
3. The method of claim 2 wherein: the step of heating said member further includes the step of keeping the heat gun in the shoe while blowing hot air therefrom for thirty seconds.
