SHOES AND METHOD FOR MANUFACTURING ORTHOPEDIC SHOES USEABLE BY DIABETES MELLITUS PATIENTS SUFFERING FROM DIABETIC PATHOLOGIC FOOT CHANGES Russian patent published in 2002 - IPC

FIELD: medical engineering; foot-wear engineering. SUBSTANCE: device has lining and upside layer, insertable insole and sole with fastening members and tongue. Additional inlay member is introduced into design which layers are not bound to each other. Upside layer and leather lining intermediate products are selected as integral and single-seam pieces. The insertable insole is multilayer member allowing to release pressure upon foot articulations in standing position. The insertable insole set is removable from the shoes to give additional space for comfortably positioning foot taking into consideration spatial parameter changes taking place in the course of the day. The tongue is attached to the external surface of shoe upside with sutures. Lining (leather lining) of shoes and insole layer engageable with foot are manufactured from plastezote material. Method involves modeling shoes, covering boot-tree and insertable multilayer insole and sublayer insole with polyethylene film. Next to it, leather lining is pulled over the boot-tree and the lining intermediate product is attached to the main soft insole and redundant material is cut off. Shoe is modeled by drawing upper border line and frontal quaters line over the lining, laying tape and gluing counter member to the lining. The so produced semifinished product The integral upside layer intermediate product is pulled over the so manufactured semifinished product. Shoe relief covered with decorative and strengthening cords is drawn and mark is laid. Semifinished shoe is uncovered along the lines of the front quaters and the shoe is taken off from the boot-tree after gluing sole. Then, soft collar is attached by suturing along the upper border and upper accessory members are sutured to the union member and the front quaters through the lining and shoe upside part. EFFECT: improved quality of shoes. 4 cl, 14 dwg, 1 tbl
