SHOE PLATE WITH VENTILATION Russian patent published in 2010 - IPC A43B17/08 

FIELD: individual supplies.

SUBSTANCE: invention is related to footwear industry, in particular to designs of ventilated shoe plates, which are used to improve shoe comfort and may be used for instance for sport and casual footwear. Ventilated shoe plate of elastic material 1 comprises form on its external surface, which corresponds to anatomic structure of foot, and bulges in heel part and toe cluster part. The latter are arranged so that they produce loop-like form. Shoe plate comprises cavities for air exhaust. Elastic material used for shoe plate is material with Shore hardness of 17-20. Bulges on external surface of shoe plate in section are arranged with height of 3-5 mm and width of 3-5 mm and are grouped in heel 2 and toe cluster parts with concentric loop-like open rows. Bulges fill surface with distance between them of 3-5 mm and with formation of grooves 3 between them for air, having width of 3-5 mm. Besides in heel part there are bulges arranged in one open concentric loop-like row in direction towards outer contour of shoe plate with grooves between bulges facing outer contour of shoe plate, ending on outer contour of shoe plate towards toe with formation of cavity 6 for air exhaust. In toe cluster part bulges 4 in area of metatarsal bone heads arrangement are grouped by two concentric open loop-like rows with grooves 5, arranged along longitudinal arch and neighbouring heel group of bulges, and directed towards inner contour of shoe plate between heel rounding and longitudinal arch with formation of cavity 7 for air exhaust. Shoe plate additionally on external side facing foot is duplicated with material impregnated with bactericide and aromatic additives, for improvement of hygienic properties.

EFFECT: improved comfort of internal shoe space as a result of better heat-mass-air exchange in areas of high perspiring, by means of directed air motion, both into toe and heel parts via cavities formed by concentric open loop-like bulges on surface of shoe plate and plantar surface of foot, with simultaneous massage action, as a result of even arrangement of bulges on surface of shoe plate, filling areas that correspond to most protruding sections of foot in heel part and toe cluster part, and with simpler formation of bulges that produce cavities together with foot.
