Complex estimation of properties of modern shoe cardboards for basic insoles

The article is devoted to the complex research the properties of modern shoe cardboards for basic insole of foreign production. Researches of rationed factors row of cardboards of quality for insole base are conducted, as well as such unrationed factors as endurance and stability under repeated bending, characterizing the behaviour of material in the process of exploitation of shoe. On results the conducted complex research the brands of cardboards, possessing the best complex of physico-mechanical properties and in the most degree corresponding to the requirements, to basic insoles material are determined.
