SHOE SOCK Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: shoe sock comprises supporting plate whose bunch and heel portions are provided with through holes arranged along concentric circles corresponding to pedopuncture zones of the foot. These holes receive springs statically pressed-down by upper cover plate and lower plate glued on the supporting plate. Positive effect is based on relative compensation of vibration waves propagating in the material of supporting plate and through the system of springs, and on attaining the lowermost natural frequency of vibration-suppressing system of about several Hertz along with a high quality of flexible members. EFFECT: higher efficiency of suppressing impact loads on foot. 3 dwg
