with reference to fig1 to 6 , a first embodiment of a stabilizing insole in accordance with the present invention comprises a base ( 30 ), a heel pad ( 10 , 10 a ) and a forefoot pad ( 20 ) and may further have a massaging bulge ( 25 ). the base ( 30 ) is flat , is shaped to correspond to a shoe sole and has a top surface and a bottom surface . the top and bottom surfaces are flat and parallel to each other . the heel pad ( 10 , 10 a ) may be oval , is formed on the base ( 30 ) and protrudes from the top surface of the base ( 30 ). the heel pad ( 10 , 10 a ) contacts and supports a heel of a user &# 39 ; s foot in a contacting area ( c ), as shown in fig5 . the heel pad ( 10 , 10 a ) has an outer surface and a heel supporting segment ( 110 ) and may further have an inclined front surface ( 11 ) and a sloping rear surface ( 12 ). the heel supporting segment ( 110 ) is formed on the heel pad ( 10 , 10 a ), mainly supports the heel of the foot and has a flat outer surface parallel to the top and bottom surfaces of the base ( 30 ). in a variant of the heel pad ( 10 a ), the heel supporting segment ( 110 ) is formed entirely on the heel pad ( 10 a ) so that the outer surface of the heel pad ( 10 a ) in uniformly flat , as shown in fig2 . in another variant of the heel pad ( 10 ), the flat outer surface of the heel supporting segment ( 110 ) is substantially semi - oval and has a curved front edge and a linear rear edge . the inclined front surface ( 11 ) is u - shaped and is formed on outer surface of the heel pad ( 10 ) adjacent to the curved front edge of the heel supporting segment ( 110 ). a thickness of the heel pad ( 10 ) corresponding to the inclined front surface ( 11 ) is gradually decreased from the curved front edge . the sloping rear surface ( 12 ) is substantially semi - oval and is formed on the outer surface of the heel pad ( 10 ) adjacent to the linear rear edge of the heel supporting segment ( 110 ), as shown in fig5 and 6 . a thickness of the heel pad ( 10 ) corresponding to the sloping rear surface ( 12 ) is gradually decreased from the linear rear edge . furthermore , the heel supporting segment ( 110 ) has rigidity higher than rigidity of parts of the heel pad ( 10 ) corresponding respectively to the inclined front surface ( 11 ) and the sloping rear surface ( 12 ). the forefoot pad ( 20 ) is tongue shaped , corresponds uniquely to a right or left foot , is attached to the base ( 30 ) and is formed on the base ( 30 ) and protrudes from the top surface of the base ( 30 ). the forefoot pad ( 20 ) contacts the heel of the foot in two transversely arranged contacting areas ( a , b ), as shown in fig5 . the forefoot pad ( 20 ) has an outer surface and a forefoot supporting section ( 210 ) and may further have an inclined front surface ( 21 ) and a concave rear surface ( 22 ). the outer surface of the forefoot pad ( 20 ) in the first embodiment is a top surface . the forefoot supporting section ( 210 ) is formed on the forefoot pad ( 20 ) and has a flat upper surface parallel to the top and bottom surfaces of the base ( 30 ). the forefoot supporting section ( 210 ) mainly supports a forefoot of the foot . in a variant of the forefoot pad ( 20 ), the forefoot supporting section ( 210 ) has a convex front edge and a concave rear edge . the inclined front surface ( 21 ) is formed on the outer surface of the forefoot pad ( 20 ) adjacent to the convex front edge of the forefoot supporting section ( 210 ). a thickness of the forefoot pad ( 20 ) corresponding to the inclined front surface ( 21 ) is gradually decreased from the convex front edge . the concave rear surface ( 22 ) is formed on the outer surface of the forefoot pad ( 20 ) adjacent to the concave rear edge of the forefoot supporting section ( 210 ). a thickness of the forefoot pad ( 20 ) corresponding to the concave rear surface ( 22 ) is gradually decreased from the concave rear edge . furthermore , the forefoot supporting section ( 210 ) has rigidity higher than rigidity of parts of the forefoot pad ( 20 ) corresponding respectively to the inclined front surface ( 21 ) and the concave rear surface ( 22 ). the massaging bulge ( 25 ) is formed on the top base ( 30 ), protrudes from the top surface of the base ( 30 ), is located adjacent to the forefoot pad ( 20 ) and may press and massage a chinese pressure point named “ yongquan ” on the sole of the foot to stimulate and maintain health of the kidneys . yongquan is located between the first and second metatarsals of the foot near the arch . the massaging bulge ( 25 ) has a tip ( 251 ) that may be flat and presses the yongquan . the massaging bulge ( 25 ) may be formed adjacent the concave rear surface ( 22 ). a method for using the stabilizing insole in accordance with the present invention comprises a providing step and a mounting step . the mounting step comprises mounting the stabilizing insole with the heel supporting segment ( 110 , 110 b ) of the heel pad ( 10 , 10 a , 10 b ) and the forefoot supporting section ( 210 , 210 b ) of the forefoot pad ( 20 , 20 b ) in a shoe to support a user &# 39 ; s heel and forefoot of a foot . with further reference to fig7 , the stabilizing insole may be formed on one of a pair of slippers and positioned to correspond to a user &# 39 ; s heel or forefoot . the base ( 30 a ) serves as a sole of the slipper . with reference to fig8 , a second embodiment of a stabilizing insole is similar to the first embodiment however the heel pad ( 10 b ) is formed on and protrudes from the bottom surface of the base ( 30 ) and the outer surface of the heel pad ( 10 b ) is a bottom surface . the forefoot pad ( 20 b ) is formed on and protrudes from the bottom surface of the base ( 30 ) and the outer surface of the heel pad ( 20 b ) is a bottom surface . the massaging bulge ( 25 ) is formed on and protrudes from the top surface of the base ( 30 ). the stabilizing insole supports a user &# 39 ; s feet to decrease the area of force and form three support points so the user does not twist his or her ankle . even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description , together with details of the structure and function of the invention , the disclosure is illustrative only . changes may be made in the details , especially in matters of shape , size , and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed .
