STRENGTHENING INDOOR MATERIAL FOR SHOES OR BOOTS SHOES OR BOOT HEELING AREA WITH THIS MATERIAL AND PROCEDURE FOR STRENGTHING THE HEELING AREA ON SHOES OR BOOTS

摘要

A sheet-form or piece-form, stiffening shoe inner material is adapted for the heel region of a shoe and is capable of being processed thermoplastically or by solvent action, the shoe inner material comprising a single-layer fibrous structure charged or filled with at least one plastics material having a stiffening effect at normal temperature up to about 60 DEG C in a quantity of from 0.1 to 0.9 kg per square metre of fibrous structure. The heel region of the shoe consists of only two layers (upper material and the new shoe inner material) instead of the conventional three layers (upper material, rear cap and slip strap).
