Method for realising a shoe and a shoe obtained with the method

Abstract

A shoe has an upper, an insole, and a bottom with a base having an edge extending vertically upwards to define a perimeter abutment. A method of making the shoe includes providing an open upper, bringing into contact an internal perimeter edge of the upper with the insole, placing a first seam between the upper and the insole to obtain an insole-upper unit, and positioning the same in the bottom so that a lower portion of the insole-upper unit abuts the bottom and the perimeter portion of the insole-upper unit abuts the internal face of the perimeter abutment, obtaining an insole-upper-bottom assembly. References are marked on the external side of the upper of the insole-upper-bottom assembly adjacent the edge of the bottom's perimeter abutment to guide positioning of the insole-upper-bottom assembly, with placement of a second seam joining the bottom to the upper of the insole-upper unit.

1 . A method for realising a shoe comprising: an upper;
 an insole which comprises a lower surface, destined to be facing downwards when the insole is associated to the upper, an upper surface destined to be facing upwards to abut, when the shoe has been completed, a user's foot, and a perimeter edge having a determined profile and thickness; a bottom that comprises a base an edge of which extends vertically upwards to define a perimeter abutment which delimits, in said bottom, a housing seat, said method comprising following steps:   a) obtaining an upper of an open type of a corresponding model;   b) bringing into contact the internal perimeter edge of the upper with the corresponding insole in order to carry out a first seam between the upper and the insole and obtain an insole-upper unit;   c) positioning the insole-upper unit in the seat of the bottom in such a way that the lower portion of the insole-upper unit abuts the internal face of the base of the bottom and the external perimeter portion of the insole-upper unit, with the first seam, abuts the internal face of the perimeter abutment in order to obtain an insole-upper unit and bottom assembly;   d) marking references on the external side of the upper of the insole-upper unit and bottom assembly adjacent to the edge of the perimeter abutment of the bottom;   e) maintaining the positioning of the insole-upper unit and bottom assembly so that the references on the external side of the upper are maintained adjacent to the edge of the perimeter abutment of the bottom and at the same time carrying out a second seam to join the bottom to the upper of the insole-upper unit and obtain the shoe.   
     
     
         2 . The method of  claim 1 , wherein between step b) and step c), a step b*) is included in which the insole-upper unit is positioned on a corresponding die for shoes. 
     
     
         3 . The method of  claim 2 , wherein between step b*) and step c) a step b**) is included in which the insole-upper unit is stretched in order for the upper to adhere perfectly to the die and for the profile thereof to be copied. 
     
     
         4 . The method according to  claim 2 , wherein between step d) and e) a step d*) is included in which the insole-upper unit and bottom assembly is extracted from the die. 
     
     
         5 . The method of  claim 1 , wherein step b) is actuated using an insole having an incision that originates on the lower surface and which penetrates the thickness of the insole in an oblique direction so as to extend towards the perimeter edge, the incision being such as to extend in a closed loop and flank the perimeter edge and wherein in step b) the internal perimeter edge of the upper is brought to abut against the perimeter edge of the insole so that the first seam is partly concealed in the incision. 
     
     
         6 . The method of  claim 1 , wherein step b) is carried out using an insole which comprises a perpendicular flank that is solidly constrained to the lower face of the insole, is loop-closed and profiled in such a way as to follow the perimeter profile of the insole at an appropriate distance from the external edge of the insole, and wherein in said step b) the perimeter edge of the upper is flanked externally of the perpendicular flank of the insole and aligned in height thereto so that the first seam is between the upper and the perpendicular flank. 
     
     
         7 . The method of  claim 6 , wherein between step b**) and step c) a further step b***) is included wherein a soft insert is associated to the part internally delimited by the perpendicular flank which, in following step c) will be imprisoned between the corresponding lower face of the insole and the base of the bottom to define an insole-upper unit and bottom assembly. 
     
     
         8 . A shoe comprising: an upper; an insole comprising a body in turn comprising a lower surface, destined to be facing downwards when the insole is associated to the upper, an upper surface destined to be facing upwards to abut, when the shoe has been completed, a user's foot, and a perimeter edge having a determined profile and thickness; a bottom comprising a base an edge of which extends vertically upwards to define a perimeter abutment which delimits, in the bottom, a housing seat ESA, the upper and the insole being joined by means of a first seam so as to obtain an insole-upper unit and the insole upper unit being joined by a second seam to the bottom in order to obtain the shoe. 
     
     
         9 . The shoe of  claim 8 , wherein the first and second seam are looped respectively on the insole-upper unit and on the insole-upper unit and bottom assembly obtained following positioning of the insole-upper unit in the seat of the bottom. 
     
     
         10 . The shoe of  claim 8 , wherein the insole comprises a perpendicular flank that is solidly constrained to the lower face of the insole, is loop-closed and profiled in such a way as to follow the perimeter profile of the insole at an appropriate distance from the external edge of the insole, wherein the shoe comprises a movable insert positioned in the part internally delimited by the perpendicular flank, so as to be imprisoned between the corresponding lower face of the insole and the base of the bottom.
