An insole for use as a replacement insole or for permanent installation in a shoe or other item of footwear is of sandwiched construction with a flexible, moldable nonsetting material inside, so that the upper surface of the insole molds and conforms to the bottom of the foot of the wearer. The insole is glued together, with an overlap of the top innersole piece folded under and adhered to the bottom of an upper subsole or shoe board immediately below. In specific areas at the tips of the toes and the heel, there is stitching through the thickness of the insole, spaced inwardly a short distance from the edge of the insole, to prevent excessive flow of the moldable material and consequent bottoming out of the foot in these areas.

Insole with moldable material

A shoe sole construction is provided with a flexible bladder which is only partially filled with a non-compressible fluid. Preferably the fluid is water. The partially filled water bladder allows the water to flow from one portion of the bladder to other portions of the bladder during the walking cycle to provide proper support and maximum comfort and stability for the wearer of the shoe.
