VIBRATION-PROOF SHOES Russian patent published in 2012 - IPC A43B7/00 

FIELD: personal use articles.

SUBSTANCE: vibration-proof shoes are proposed which contain a sole and an upper part, and also a hermetic cavity placed in the lower part of the shoe and enfolding a foot. The hermetic cavity is equipped with a check valve to be connected with the external environment and a source of compressed air. Rigidity of different parts of the hermetic cavity is made different: the lateral surface may be less rigid than the upper and lower surfaces, or vice versa. At the same time the hermetic cavity can be formed by a membrane fixed along the perimetre of the side walls of the shoe. The cavity is divided by rigidity ribs for at least three separate cavities interconnected by damping sleeves. The sole of the shoe is equipped with protective insert, made of elastic material more rigid than the sole, which serves as an additional elastic element in the vibration-proof system "shoes - operator". Over the hermetic cavity an elastic sealing shell equidistant and congruent to it is located, filled with silicone fluid.

EFFECT: increased protective qualities of shoes.
