PARTS OF FOOTWEAR ## Abstract The present invention provides an outsole, comprising, at least one recess located at a ground engaging or outer surface of the outsole and having: (a) a depth of between 10% to 95% of the maximum thickness of the outsole; and (b) an area that covers between 10% to 95% of the entire ground engaging or outer surface of the outsole. ## Claims ### Claim 1 A footwear, comprising, an outsole, comprising: at least one recess located at a ground engaging or outer surface of the outsole and having: (a) a depth of between 10% to 95% of the maximum thickness of the outsole; and (b) an area that covers between 10% to 95% of the entire ground engaging or outer surface of the outsole; and two curved solid body hard protuberances having a shore hardness of between 65 to 90 Shore A, protruding out from said ground engaging or outer surface of said outsole, and adapted to be removably inserted into said at least one recess, wherein each protuberance has a different curved outer contour and wherein said two protuberances bases occupy between 50% to 95% of an area of the at least one recess, and wherein each protuberance is detachably connected to the at least one recess via two or more connectors fixating each protuberance to the at least one recess. ### Claim 2 (depends on 1) The footwear of claim 1, wherein the two curved protuberances are asymmetrical. ### Claim 3 (depends on 1) The footwear of claim 1, wherein the two curved protuberances are defined by a variety of arches of different radiuses which are tangent to each other. ### Claim 4 (depends on 1) The footwear of claim 1, wherein an outer contour of at least one of said two curved protuberances and an outer contour of said outsole form a continuous curvature. ### Claim 5 (depends on 1) The footwear of claim 1, wherein each curved protuberance comprises a portion connectable to the recess and a ground-engaging portion, wherein the portion connectable to the recess is harder than the ground-engaging portion. ### Claim 6 (depends on 1) The footwear of claim 1, wherein each protuberance is different with respect to at least the location of the peak, a convexity, shore-hardness, or any combination thereof. ### Claim 7 (depends on 1) The footwear of claim 1, wherein a base of a single protuberance occupies at least 60% of an area of a single recess and a first perimeter of said base of said single protuberance is adapted to fit a second perimeter of said single recess. ### Claim 8 A kit, comprising: the footwear comprising an outsole, comprising: at least one recess located at a ground engaging or outer surface of the outsole and having: (a) a depth of between 10% to 95% of the maximum thickness of the outsole; and (b) an area that covers between 10% to 95% of the entire ground engaging or outer surface of the outsole; and two curved solid body hard protuberances having a shore hardness of between 65 to 90 Shore A, protruding out from said ground engaging or outer surface of said outsole, and adapted to be removably inserted into said at least one recess, wherein each protuberance has a different curved outer contour and wherein said two protuberances bases occupy between 50% to 95% of an area of the at least one recess, and wherein each protuberance is detachably connected to the at least one recess via two or more connectors fixating each protuberance to the at least one recess. ### Claim 9 (depends on 8) The kit of claim 8, wherein said two solid body curved protuberances at their peak are higher in at least 10% than a maximum depth of said at least one recess. ### Claim 10 (depends on 8) The shoe kit of claim 8, wherein each one of said protuberances comprises a peak and wherein a location of said peak is adapted to ameliorate at least one gait related pathology. ### Claim 11 (depends on 8) The shoe kit of claim 8, wherein the height of each protuberance at their peak is adapted to ameliorate at least one gait related pathology. ### Claim 12 (depends on 8) The kit of claim 8, wherein the two curved protuberances are asymmetrical. ### Claim 13 (depends on 8) The kit of claim 8, wherein the two curved protuberances are defined by a variety of arches of different radiuses which are tangent to each other. ### Claim 14 (depends on 8) The kit of claim 8, wherein an outer contour of at least one of said two curved protuberances and an outer contour of said outsole form a continuous curvature. ### Claim 15 (depends on 8) The kit of claim 8, wherein each curved protuberance comprises a portion connectable to the recess and a ground-engaging portion, wherein the portion connectable to the recess is harder than the ground-engaging portion. ### Claim 16 (depends on 8) The kit of claim 8, wherein each protuberance is different with respect to at least the location of the peak, a convexity, shore-hardness, or any combination thereof. ### Claim 17 (depends on 8) The kit of claim 8, wherein a base of a single protuberance occupies at least 60% of an area of a single recess and a first perimeter of said base of said single protuberance is adapted to fit a second perimeter of said single recess.
