Abstract
An orthotic support insole having a body including each of an uppermost anti-microbial lining, an intermediate foam layer, a rigid stabilizer insert and a bottom-most thermo-formable foam layer. An extending edge of the body corresponds to at least a heel cup and intermediate sides being fused along an outer perimeter edge to prevent delamination. The body includes a non-standard thickness along an axial length thereof and the fused perimeter edge extends to a location proximate a forward extending edge portion of the body.

An orthotic support insole, comprising:
- a body including each of an uppermost anti-microbial lining, an intermediate foam layer, a rigid stabilizer insert and a bottom-most thermo-formable foam layer;
- and
- an extending edge of the body corresponding to at least a heel cup and intermediate sides being fused along an outer perimeter edge to define a pinched profile to prevent delamination.
A process for forming an orthotic support insole, comprising the steps of:
- forming within a die a body including each of an upper layer, a rigid stabilizer insert and a bottom-most thermo-formable foam layer;
- and
- fusing together an extending edge of the body corresponding to at least a heel cup and intermediate side locations to define a pinched profile to prevent delamination.
