The blank forming the upper is hedl together by 36/48 outwardly pointing seams.

  • the invention relates to a method of making shoes, to the finished shoe produced by the method, to an appliance required for performing the method and to the shape of the blanks from which the proposed shoes are made.
  • Hitherto shoes were made by attaching the shoe material, known as the upper, to an insole by adhesive bonding, tacking or sewing.
  • proper support was required for the insole and for this purpose use was made of a last with a flat underside and sharply angled peripheral edges.
  • another known type of shoe is the California Shoe or Moccasin which is likewise made with the aid of a last with a flat underside and a peripheral angular edge.
  • Another known arrangement comprises providing a knitted footing (part of knitted hose) with a sole that is adhesively affixed thereto.
  • this kind of footwear is inappropriate for outdoor wear.
  • Another drawback of conventional methods of manufacture is that elements, such as heels, caps, hinges, steel joints or the like must be incorporated in the shoe to provide sufficient support for the foot. This means that at least parts of the interior of the shoe must be lined to cover the heel cap and the internal seams.
  • the present invention which has for its object the production by simple means of a well fitting properly shaped shoe which permits the wearer to walk in a manner that is orthopaedically correct in as much as the weight of the body is spread over the entire base of the foot, as is the case for instance when walking barefoot.
  • this is achieved by first forming from a blank an upper resembling, a sock which completely envelops the foot, drawing this blank on a last that corresponds to the natural shape of the foot, i.e., lacking peripheral edges, and then with the omission of an insole directly bonding said upper to a bottom member which in one part incorporates the outer sole, heel cap and stiffening respectively guide elements for the foot.
  • the blank for forming the upper is held together by seams pointing outwards.
  • the last carrying the tautly stretched upper may be introduced into a mould shaped to form the complete bottom part of the shoe, comprising the outer sole, the heel cap, stiffening elements and possibly the heel, from a plastics composition such as polyurethane or the like, which sets and forms an indissoluble bond with the upper.
  • a plastics composition such as polyurethane or the like
  • the principal feature of a shoe made by the method according to the invention is that it lacks an insole, that the upper completely envelops the foot like a sock and that the other parts of the shoe, such as the outer sole, heel cap, heel as well as stiffening and guide elements are injection moulded as an integral member for instance of polyurethane, directly to the upper.
  • the material of the upper Owing to the use of a last which exactly conforms to the natural shape of the foot, and which tautly carries the stretched upper the material of the upper is maintained in the natural shape of the foot during the process of moulding and the subsequent process of curing and setting.
  • the internal supporting surface of such a shoe is not then a flat surface but a shaped bed which substantially reproduces the natural contours of the foot, and which thus sleekly envelops the foot.
  • FIGS. 1 to 6 are different perspective views of the last used for making the proposed shoe
  • FIGS. 7 and 7a illustrate a blank for making an upper for the proposed shoe
  • FIGS. 8 to 12 are different perspective views of an upper according to the invention.
  • FIG. 13 is a blank for a different shape of an upper
  • FIGS. 14 to 17 is the upper formedfrom the blank according to FIG. 13 and FIG. 18 is the finished shoe made by using the upper according to FIG. 14.
  • a last composed of two hingeably connected components 1 and 2, and having no sharp edges or completely flat surfaces, i.e., precisely conforming with the actual contours of a natural human foot.
  • the two components of the last can behingeably tilted to permit the last to be introduced into a shoe without strain and the shoe stretched when the last is extended.
  • the last does not serve, as hitherto, for supporting an insole to which the upper is attached with the aid of an adhesive, by tacking or sewing.
  • the only purpose of the last is to keep an upper which envelops the foot like a sock in a state in which it is taut and retains the shape of the foot whilst the bottom of the shoe is formed on the upper.
  • the upper that is used for making a shoe as illustrated in FIGS. 8 to l2' comprises two blanks which are shown in FIGS. 7 and 7a.
  • the larger sized'blank consists of a portion comprising a sole 3 and sidewall portions 4, 4' as well as a portion 5 for enclosing the toes.
  • the blank is converted to the shape of the foot by seaming the sidewall portion 4 to the edge of the sole portion 3 along the dot-dash line 6.
  • the seam 7 which connects the sidewall portions 4 and 4' is then formed on the outside of the heel.
  • the top of the upper is formed by avamp 8 shown in FIG. 7a. This is connected by a seam 9 to the toe portion of the blank 5 along the dashed lines indicated in the two drawings. It is an important feature that the seams 6, 7 and 9 are formed on the outside in a region of the foot where they cannot exert pressure on the foot.
  • the seams are produced in the conventional way.
  • the vamp may be provided'with buckles 10 or straps 11 or other ornamentation as particularly shown in FIGS. 11 and 12.
  • FIGS. 8 to 12 which envelops the foot of a wearer like a sock.
  • FIG. 13 is a blank for forming an upper with a closed top.
  • the sole 3 is an appendage of the sidewall portion 4, the two sidewalls 4' and 4 being connected by a portion 8 of material which forms a marginal flange at its external edge.
  • a similar flange I2 is formed on the sole portion 3.
  • the blank is again sewn together to conform with the shape of the foot, the side portion 4 being attached to the outside of the sole 3 by a seam 13.
  • the seam 14 is formed on the outside of the heel and connects the rear ends of the sidewall portions 4, 4.
  • the marginal flange 12 which is slightly notched around its periphery is bent around the edge of the sole, possibly over an inserted former, and conveniently adhesively attached to the sole.
  • the resultant shoe upper is illustrated in FIGS. 14 to 17.
  • the longitudinal seams 13 will again be located an the inside of the arch of the foot and the seam 14 on the outside of the heel.
  • the upper may be additionally provided with decorative seams l5, edge bindings 16 and sewn on lacings or the like. In every case the upper envelops the foot like a sock. It is drawn and stretched into the correct shape of a foot by the insertion of the last 1, 2.
  • FIGS. 11 and 17 show the way in which the last is inserted.
  • the finished shoe as illustrated in FIG. 18, can be taken out of the mould.
  • the heel and possibly the sole 18 may be permanently flexible parts of the shoe.
  • stiffenings or elastics inserts can be introduced into the mould before the bottom of the shoe is moulded. Conveniently use may be made of a plastics material which foams inside the mould.
  • a method of making shoes comprising the steps of pulling tightly an upper blank in sock like form about a last having exclusively rounded portions substantially conforming to the anatomical shape of a foot to be used in the shoe as to enclose completely and sock like said foot, said blank forming a shoe sole portion contacting the bottom of the foot. and forming seams folding outwardly pointing away from the last and running along an outer longitudinal side, and holding said blank in said sock like form on said last, and
  • heel cap, and stiffening elements is integrally formed and permanently connected with the aid of a bonding agent to the upper blank drawn on said last conforming with the natural contour of the foot.
