Definitions

  • This invention relates to a method of making an article of footwear, such as a sports shoe or boot, and which comprises an upper, an insole board secured to the upper to form an upper/insole board assembly, and an outsole secured to the insole board/upper assembly.
  • insole shape which conforms even approximately to the actual shape of the underside of a typical person's foot.
  • the insole therefore has been substantially planar, when assembled with an upper and an outsole, and with the result that the underside of the human foot only makes contact with the insole over possibly 60% to 70% of the surface area of the insole.
  • the arch region of the foot remains unsupported, and out of contact with the insole, and which is undesirable for at least two reasons .
  • This region has a venous pad i.e. it is a region having a high proportion of veins near the surface, and medical science now recognises that this is an important area, and therefore it would be advantageous, if possible, to provide an improved design of insole of a boot or shoe which gives additional support for the foot in this region.
  • the lack of adequate support for the arch region results in poor circulation of blood through this region of the foot and can, in some circumstances, result in reduced flow of blood to the head, and consequent fainting.
  • Soldiers on punishment or guard duty, standing still for lengthy periods are liable to faint, if attention is not given to maintaining regular flexing of the toe or foot muscles, or other movements of the foot.
  • the present invention therefore seeks to provide an improved design of insole for a boot or shoe (and especially for use in playing sport) , in which the insole has a greater area of contact with the underside of the foot, and in particular with the underside of the arch region.
  • a method of making an article of footwear on a last and having an upper, an insole board assembled with the upper, and an outsole secured to the underside of the assembly of the upper/insole board comprises the steps of: providing a last having an undulating surface which corresponds generally to the shape of the underside of a human foot, and which includes a concave region generally following the shape of the underside of the arch region of the foot; applying the insole board to the undulating surface of the last, and causing the board to follow the shape of the last; applying an upper to the last and securing the upper to the insole board to form an upper/insole board assembly; and applying an outsole to the upper/insole board assembly.
  • An article of footwear is therefore made having an insole board with a shape conforming substantially to the underside of the foot, and especially providing contact with and support for the arch region. Therefore, in use, lowered average contact pressure will be applied to the underside of the foot, and in addition a massaging effect is applied to the venous region of the foot in order to promote blood flow through the foot and generally through the body of the wearer .
  • the means by which the insole board is caused to follow the undulating surface of the last can take any convenient form.
  • a V-shaped recess is formed initially in a heel region of the insole board, and the opposed edges of which are subsequently pulled together, and then secured together (preferably by stitching) , in order to shape the insole board to follow the shape of the undulating surface of the last, and a longitudinally extending strip is also secured to the exposed face of the insole board.
  • the insole board has a "waisted" form in a central region of the board and which is defined on one side of the board, by a shallow concave depression, and on the other side of the board by a much deeper concave depression. This arrangement of waited form is particularly suitable to allow the insole board to be applied to the surface of the last and permanently to take-up the shape of the last when subsequent manufacturing steps have been completed.
  • Figure 1 is a side view of an improved design of last on which can be carried out a method of manufacture according to the invention for making an improved design of article of footwear;
  • Figure 2 is a side view, similar to Figure 1, showing how two component parts of the last shown in Figure 1 can break-open to assist release of the article of footwear formed thereon;
  • Figure 3 is an under plan view showing the profile of the last shown in Figures 1 and 2;
  • Figure 4 is a plan view of a first arrangement of insole board for use in making the article of footwear
  • Figure 5 is a plan view of the insole board shown in Figure 4, but after manipulation to close a V-shaped recess in the heel area shown in Figure 4, to form a stitched-together assembly as shown in Figure 5;
  • Figure 6 is a plan view of a longitudinally extending strip for securement to the insole board of Figure 5;
  • Figure 7A is a plan view of the insole board of Figure 5, and with the longitudinal strip of Figure 6 secured thereto;
  • Figure 7B is a longitudinal section taken on the section line B-B in Figure 7a;
  • Figure 8A is a side view, and also rear view, of the insole board secured on the underside of the last shown in Figures 1 and 2;
  • Figure 8B is a side view, similar to Figure 8a, taken in cross section through one side;
  • Figure 9A is a side view of an upper fitted on the last shown in Figures 1 and 2;
  • Figure 9B is a cross sectional view of the upper lasted to the last of Figures 1 and 2;
  • Figure 10A is a side view showing the upper stitched together to the insole board shown in Figure 7A, prior to being fitted on the last;
  • Figure 10B is a cross sectional view comprising an assembly of Figures 8 and 9;

  • Figure 12 is a cross sectional view of the lasted upper taken through the upper heel region, with an outsole secured thereto;
  • Figure 13 is a perspective view from the underside of the sports shoe or boot sub-assembly comprising the upper and the insole board secured together;
  • Figures 14 to 23 show a further example of the invention utilising a modified shape of insole board and securement strip to form the part-assembly to be applied to the last.
  • Figure 2 shows that the last is of two component form, and which are hinged together, and which can be broken open, as shown in Figure 2, to allow release of a boot or shoe lasted thereon.
  • Figure 3 is an under plan view showing the profile of the last.
  • An article of footwear to be made on the last shown in Figures 1 to 3 comprises a boot or shoe, and preferably takes the form of a sports boot.
  • the boot will be assembled on the last from three separate main components, namely an upper, an insole board to which the upper is secured along its edges, (to form a part-assembly) , and an outsole secured to the underside of the part assembly, to complete the formation of the boot.
  • Figure 4 is a plan view of an insole board 10 which, after subsequent fabrication, is intended to be applied to the underside of the last.
  • the last is designated generally by reference 11, and comprises two separate components 12a and 12b, which can be hinged to an open position, as shown in Figure 2, to allow an article of footwear which has been lasted thereon to be removed.
  • the last 11 has an undulating lower surface 13 which corresponds generally to the shape of the underside of a human foot, and which includes a concave region 14 generally following the shape of the underside of the arch region of the foot.
  • Figure 4 shows the insole board 10, prior to subsequent fabrication, which is in two stages, the first of which is shown in Figure 5, and the second of which will be apparent from Figures 6 and 7a.
  • the insole board is formed initially with a V-shaped recess 140 i.e. a cut out, in a heel region 15 of the insole board 10, and the opposed edges 16 of the recess 140 are subsequently pulled together, in order to shape the insole board 10, and the edges 16 are subsequently joined together by stitching, as shown in Figure 5.
  • the fabrication of the insole board 10, so as to fit closely onto the undulating surface 13 of the last 11, is achieved by provision of a longitudinally extending strip 17, shown in Figure 6, and which is subsequently secured lengthwise of the insole board 10, and overlying the stitching together of the edges 16, as shown in Figure 7a.
  • any suitable adhesive or other securement of the strip 17 to the insole board 10 may be utilised, provided that it causes or allows, the part-assembly to take up permanently the profile of the last to which it is applied.
  • the profile of the insole board 10 can be seen from the section taken on B-B in figure 7a, as shown in figure 7b.
  • the insole board 10 is fabricated in such a way that it can be caused to follow the shape of the undulating surface 13 on the underside of the last 11, prior to subsequent lasting of the remaining components of the article of footwear.
  • Figures 8A and 8B show the insole board 10 applied to the undulating surface of the last
  • Figures 9A and 9B show an upper 18 applied to the last 11.
  • the upper 18 is joined to the insole board 10, prior to being fitted on the last
  • Figure 10A shows the assembly of upper and insole board after application to the last.
  • a line of stitching 19 is shown, which joins together the edges of the insole board 10 to the upper 18. This is shown in Figures 10a and 11.
  • Figure 10b is a cross- sectional view of an assembly of figure 8 and 9.
  • Figure 12 shows a cross section of the lasted upper and insole board, taken through the heel region of the boot.
  • Figure 13 is a perspective view from the underside of the boot sub-assembly comprising the upper and the insole board joined together.
  • An article of footwear is therefore capable of being manufactured on the last shown in Figures 1 to 2, and adopting the method steps described above with reference to Figures 4 to 13.
  • the article of footwear has an insole board with a substantially permanent shape conforming substantially to the underside of a human foot, and especially in providing contact with, and support for, the arch region of the foot. Therefore, in use, lowered average contact pressure will be applied to the underside of the foot, and in addition a massaging effect is applied to the venous region of the foot in order to promote blood flow to the foot, and generally through the body of the wearer.
  • the invention therefore provides a new method of manufacture, and resulting in a new article of footwear, which is quite different from what has been done before.
  • the foot of the user is fully wrapped-up by the shoe, and in effect the shape of the shoe, and especially of the insole board, is like a photographic "negative" of the underside of the foot itself.
  • the new design of manufacture of the shoe provides a much more comfortable feel to the user, and no impact points, or high pressure areas, apply to the underside of the food of the wearer. Also, no trauma is developed within the user of the shoe.
  • the construction of the shoe provides an internal shape which is designed to avoid any high pressure contact areas or points of engagement with the foot. Substantially uniform contact pressure is applied to the underside of the foot, including the arched region, and this provides improved ground support for the wearer of the shoes .
  • FIG 14 this is a view, similar to figure 4, showing a modified shape of insole board 110, having a central waisted portion 111 which is defined between a shallow concave depression 112 along one edge of the insole board, and much deeper concave depression 113 along the opposite side edge.
  • Figure 15 shows a pre-formed strip 117 which is intended to be secured to the insole board 110 as shown in figure 16. Any suitable means of securement of strip 117 to insole 110 may be utilised, and looking at the section on the line X-X in figure 16 as shown in figure 17, this shows the profile taken up by the part-assembly of the insole board 110 and strip 117.
  • Figure 18 shows counter heel sections 118, 119 and 120, and which can be assembled to form counter heel 121 as shown in figure 19.
  • Figure 20a and 20b are views showing assembly of an upper stitched to the insole board, prior to being fitted on the last.
  • Figures 21a and 21b are cross-sectional views of the assembly.
  • Figure 22 is a perspective illustration from the underside of a sports boot 122, assembled from insole board 110 and upper 118, and figure 23 is an under-plan view of the insole and upper stitched together, corresponding with figure 22.
