ABSTRACT:
An insole for shoes is a three-dimensionally shaped laminate composed of two adhesive-free formed fabrics, the formed fabric on the foot side being thin and abrasion-resistant, and the thicker formed fabric forming the base material of the insole consisting of staple fibers, having a composition of 50-60% by weight of core/sheath-polyester/copolyester fibers with a melting range of the core component of 255.degree.-260.degree. C. and of the sheath component of 110.degree.-140.degree. C., 5-15% by weight of high-shrinkage polyester fibers, and 25-40% by weight of absorbent fibers. The base material has a mass per unit area of 800-1200 g/m.sup.2 with a thickness of 0.70-0.85 cm. The insole is produced by shrinking the loosely needled base material by means of superheated water vapor, subsequently laminating the base material to an emboss-bonded and heated formed fabric by means of an adhesive compound, deep drawing of the laminate which was first heated above the melting range of the sheath component of the base material fibers inside an unheated molding press, and subsequently punching out the individual deep-drawn molded insoles.
