FIELD: shoe industry. SUBSTANCE: inner sole is composed of at least two layers of cellulose material and has toe part, heel part and intermediate part. Inner sole layers are formed by folding cellulose material at equal intervals, with toe, heel and intermediate part folding lines extending in single straight line. EFFECT: increased efficiency by effective usage of absorption capacity of inner sole material due to averaged moisture content over the whole surface, simplified construction and reduced production cost. 4 cl, 3 dwg
