INSERT INNER SOLE FOR CHILDREN'S PROPHYLACTIC SHOES Russian patent published in 2011 - IPC A43B17/00 

FIELD: personal use articles.

SUBSTANCE: invention relates to shoe industry and orthopaedic devices, namely, to design of insert inner sole for children's prophylactic shoes, and may be used to produce shoes and prosthetic-orthopaedic items. Inner sole for children's prophylactic shoes, comprising upper, intermediate and lower layers, at the same time upper layer is made of leather, intermediate layer - from foamed thermoplastic material that shapes in process of wear, and lower frame layer - from dense thermoplastic material, while intermediate layer is arranged with a groove in heel part under heel bone bump in section 0.18 D, where D - length of foot, and with even arrangement of external and internal arches in waist area with highest point in area of calcaneocuboid joint in section 0.36 D. On upper layer of inner sole in toe part there is a size scale and marking lines applied in the form of colour zones, to determine compliance of shoe size to foot length. Design and materials of inner sole help to reduce pressure concentration under foot bone bumps, absorb impact loads during walking, provide for high flexibility in fascicular part of shoes. Anatomic shape of intermediate layer of inner sole provides for proper alignment of foot, creates conditions to form its arches, providing for prevention of static deformations of children's feet. Marking lines in the form of colour zones, corresponding to permissible limits of foot toes position in shoes, make it possible to monitor compliance of shoe size to foot size, which is especially important when selecting shoes for small children, who are not able to themselves identify whether these shoes fit them or not, and also to periodically monitor compliance of shoe size with foot length as it grows.

EFFECT: design provides for proper formation of a child's foot and also for proper selection of shoe size.
