SHOE (VERSION) AND INSERT FOR SHOE Russian patent published in 1997 - IPC

FIELD: shoe industry. SUBSTANCE: shoe has sole, intermediate sole and insole. Intermediate sole is made from resilient fabric containing sleeve-shaped cylindrical members positioned at one side of fabric. Sleeve-shaped members are made from material with Shore hardness below 35 and height within the range of 3-10 mm. Each sleeve-shaped member is disposed to be deformed in plane perpendicular to its longitudinal axis. Number and location of sleeve-shaped members on intermediate sole are selected to provide for effective shock-absorbing and ventilation of shoes. Intermediate sole with sleeve-shaped members may be formed as insert and may be positioned on operative surface of sole. Other version of shoe has sole with at least one recess positioned in heel part on surface faced to foot and adapted to receive cylindrical member. Recess has rectilinear walls. Cylindrical member is formed as sleeve projecting above inoperative surface of sole and fabricated from resilient material, which fills free spaces of recess due to compressive deformation. Sleeve-shaped member is in contact with recess walls when in undeformed state. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 20 cl, 15 dwg
