INSOLE AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC A43B13/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for making an insole, which includes steps of heating a resin composition until it becomes soft, wherein said resin composition solidifies at rest, wherein said resin composition is a heated activated resin composition which is at least re-curable or re-moldable when exposed to heat; impregnating the foamed material with said resin composition, capable of repeated hardening, wherein said foamed material is configured to receive a resin composition capable of repeated hardening; saturation of said foamed material with said resin composition capable of repeated hardening, wherein said foamed material comprises a structure with open pores and is configured to be filled with said resin composition capable of repeated hardening; placing said impregnated foam material into chamber, said chamber comprising a heat-resistant material; sealing said chamber in order to avoid leakage of said resin composition capable of repeated hardening; placing said sealed chamber in lower layer of insole, wherein insole comprises at least part of foot arch pad, which is configured to receive said resin composition, capable of repeated hardening, in said sealed chamber; and applying pressure to said sealed chamber to produce an insole shape.

EFFECT: technical result consists in providing insole molding.
