Abstract
A sole construction (10) for use in a high heel shoe (60) comprises at least a first skeleton sole (11) formed from a composite material such as a carbon fibre material. The skeleton sole (11) has lasting allowances (15) defined around the perimeter thereof and adapted to receive the edges of a shoe upper (61) when incorporated in a high heel shoe (60). The skeleton sole (11) is further shaped so as to define one or more recesses (16) generally centrally therein. When incorporated into a high heel shoe (60), the enhanced strength, rigidity and flexibility of the sole construction (10) allow for the use of a range of interchangeable heel constructions (30,40,50) having different heel heights.
Description
- This invention relates to a sole construction for a high heel shoe, and to a high heel shoe formed with such a sole construction. In particular, this invention relates to a sole construction formed of a composite material to provide enhanced strength, but with reduced sole construction thickness.
- In this specification, the term “high heel shoe” is intended to refer to any kind of elevated heel arrangement having heel heights of more than 25 mm, though it is generally envisaged that preferred embodiments of high heel shoes according to the invention will have heel heights in the range of from 60 mm to 100 mm.
- Conventional high heel shoes are constructed with a sole construction comprising a structural sole component having a flat forefoot area, a raised heel area, and an arch area rising from the forefoot area to the heel area. The shoe upper is generally attached (lasted) to the sole component, and an outsole is attached to the underside of the sole component. A heel construction is affixed to the heel area, generally by means of a central screw and additional side screws. It is common for a metal shank to be incorporated into the sole construction to impart sufficient strength and rigidity to the shoe to be able to bear the weight of the wearer. However, this effectively increases the thickness of the sole construction and so reduces the amount of space available for cushioning.
- It is a principal aim of this invention to provide a sole construction for a high heel shoe having enhanced strength, which obviates the need for a metal shank to be included, and thus enables the thickness of the sole construction to be reduced. The space made available by the reduced sole construction thickness can then be used to provide increased cushioning, and thus enhanced comfort. A further aim of the present invention is to provide a sole construction with enhanced properties of rigidity and flexibility, tailored to different areas of the sole construction. These properties, together with the enhanced strength, enable the use of a single sole construction with a range of different heel heights.
- According to a first aspect of this invention, there is provided a sole construction for a high heel shoe, comprising at least a first skeleton sole formed from a composite material and having lasting allowances defined around the perimeter thereof and adapted to receive the edges of a shoe upper, and wherein said skeleton sole is further shaped so as to define one or more recesses generally centrally therein. The composite material preferably is or includes a carbon fibre material.
- The sole construction may comprise a second like skeleton sole arranged to underlie the first skeleton sole. The first skeleton sole thus constitutes an insole and the second skeleton sole constitutes a midsole. The second skeleton sole preferably has a shape complementary to that of the first skeleton sole, and is adapted to engage therewith.
- The first skeleton sole preferably comprises a substantially flat forefoot area at a first end thereof, a raised heel area at a second end thereof, and an arch area extending therebetween and rising from the forefoot area to the heel area. The second skeleton sole preferably comprises at least a heel area corresponding to the heel area of the first skeleton sole. The second skeleton sole may preferably further comprise an arch area corresponding to the arch area of the first skeleton sole, and optionally a forefoot area corresponding to the forefoot area of the first skeleton sole. In embodiments where the second skeleton sole comprises a heel area only, or heel and arch areas only, the remainder of the midsole construction may be made up by conventional materials such as leather, thermoplastic polyurethane (TPU) or rubber.
- The recesses are preferably formed in at least the arch area, and extend generally longitudinally along the first skeleton sole. The, or at least one, skeleton sole is preferably further shaped so as to define one or more strengthening ribs, generally centrally therein. As with the recesses, the ribs are preferably formed in at least the arch area, and extend generally longitudinally along the skeleton sole. The height of the ribs is preferably substantially equal to the depth of the one or more recesses.
- The or each skeleton sole may be formed from one or more layers of the composite material. The number of layers of the composite material may vary along the length of the skeleton sole, so as to control the degree of rigidity or flexibility of the different areas of the skeleton sole. In particular, the forefoot area of the first skeleton sole may be formed from fewer layers of the composite material than the arch area, and the arch area may be formed from fewer layers of the composite material than the heel area. This enables the flexibility of the boundary between the forefoot area and the arch area to be controlled, whilst still maintaining the strength and rigidity of the arch area. This flexibility of the boundary is important to enable the sole construction of the present invention to be utilised with a range of different heel heights, since this requires the sole construction to flex so as to adopt a corresponding range of different angles between the forefoot area and the arch area.
- The formation of the sole construction as hereinbefore described provides enhanced strength whilst also enabling the thickness of the sole construction to be reduced, compared to conventional sole constructions. This in turn frees up space within the shoe, allowing for additional cushioning to be included, and so also enhancing comfort for the wearer.
- The sole construction thus preferably further comprises a footbed arranged to overlie said at least one skeleton sole, said footbed being formed of a cushioning material. In preferred embodiments, the footbed will overlie the first skeleton sole (insole) which in turn overlies the second skeleton sole (midsole).
- According to a second aspect of the present invention, there is further provided a high heel shoe formed with a sole construction as hereinbefore described. The enhanced strength of the sole construction enables such a shoe to be constructed without the need for a metal shank to be included in the shoe construction, as is standard in conventional high heel shoe manufacture.
- The high heel shoe according to the second aspect of the present invention preferably comprises a sole construction as hereinbefore described, an upper, an outsole, and a heel construction. In such embodiments, the depth of the recesses of the sole construction is preferably substantially equal to the thickness of the upper.
- In preferred embodiments of high heel shoe according to the second aspect of the present invention, the heel construction is removeable. The heel construction may preferably be interchangeable with one or more alternative heel constructions, comprising a range of heel constructions of differing height. For example, the sole construction may be utilised with a range of interchangeable heel constructions having heights of 60-70 mm, 80 mm, and 90-100 mm.
- This interchangeable arrangement is enabled by the enhanced strength of the sole construction according to the first aspect of the present invention, together with the increased rigidity of the arch area and the increased flexibility of the forefoot area. By contrast, conventional sole constructions for high heel shoes generally lack the required combination of strength, rigidity and flexibility to withstand the different loads and stresses associated with the different angles at which the sole constructions will be disposed when combined with heel constructions of differing heights.
- It should be appreciated that a single sole construction according to the first aspect of the present invention is capable of engaging with each of a range of heel constructions as described above interchangeably, without the need to change the configuration of the sole construction. As such, a high heel shoe according to the second aspect of the present invention may be supplied with a range of such interchangeable heel constructions, intended to be interchanged by the wearer when desired.
- Alternatively, it is envisaged that the sole construction according to the first aspect of the present invention may be supplied to shoe manufacturers as a component part for incorporation into a high heel shoe according to the second aspect of the present invention. The manufacturer may thus utilise the same configuration of sole construction to form a range of high heel shoes of differing height.
- The interchangeable attachment of the heel constructions with the sole construction may preferably be achieved by the provision of a heel pin secured to the first skeleton sole and protruding therefrom, and a corresponding recess formed in a heel insert provided in the heel construction, said recess being adapted to receive said heel pin in a removable engagement. Examples of suitable heel engagement mechanisms are described in the inventor's EP 3,122,199.
- The outsole is preferably formed with a shape complementary to that of the sole construction, and is adapted to engage therewith. That is to say, the outsole may be formed with ribs and recesses on its top surface complementary to the underside of the ribs and recesses presented on the lower surface of the sole construction.
- In order that the present invention may be more clearly understood, preferred embodiments thereof will now be described in detail, though only by way of example, with reference to the accompanying drawings, in which:

FIG. 16 shows a lateral cross-sectional view of the forefoot area of a high heel shoe according to an embodiment of the second aspect of the present invention. - Referring first to
FIG. 1 , there is shown a first embodiment of a sole construction, generally indicated 10, according to a first aspect of the present invention, for use in a high heel shoe according to a second aspect of the present invention. Thesole construction 10 comprises afirst skeleton sole 11, also referred to herein as an insole. - The
insole 11 is formed from a layered composite material comprising carbon fibre, and presents atop surface 22 and abottom surface 23. The insole comprises a generallyflat forefoot area 12, a raisedheel area 13, and anarch area 14 extending therebetween, and rising from theforefoot area 12 to theheel area 13. Theinsole 11 is provided around its perimeter with lasting allowances adapted to receive the edges of a shoe upper (not shown inFIG. 1 ) when thesole construction 10 is incorporated into a high heel shoe, as will be described in more detail below with reference toFIGS. 9 to 12 . - The
insole 11 is constructed so as to have acentral recess 16 formed in thetop surface 22 of theinsole 11, andribs 17 upstanding from saidsurface 22. The embodiment ofinsole 11 shown inFIG. 1 has asingle recess 16 and pair ofribs 17 generally parallel thereto, though in other embodiments a variety of different arrangements ofrecesses 16 andribs 17 may be used. The recesses and ribs serve to enhance the strength and rigidity of theinsole 11, particularly in thearch area 14 andheel area 13, meaning that it is not necessary to utilise a metal shank in the manufacture of the high heel shoe. - The
heel area 13 is provided with a mountingpoint 18 for a heel pin (not shown inFIG. 1 ), as will be described in more detail below with reference toFIGS. 4 to 6 . The thickness of theinsole 11 around the mountingpoint 18 is greater than that of the surroundingheel area 13, which is achieved by adding additional layers of the composite material. The mountingpoint 18 can also be used to affix a standard high heel construction, as will be described below with reference toFIGS. 9 and 12 . - The degree of flexibility and rigidity of the
insole 11 can be controlled by the layering of the composite carbon fibre material. In particular, it is desirable that thearch area 14 is formed from more layers of the composite carbon fibre material than is theforefoot area 12. Aboundary area 19 is thus defined between thearch area 14 and theforefoot area 12, in whichboundary area 19 the number of layers of material reduces and so the thickness of theinsole 11 tapers towards theforefoot area 12. The strength and rigidity of thearch area 14 is thus maintained, whilst allowing theinsole 11 to be flexible in theboundary area 19, which is important for utilising thesole construction 10 with a range of heel constructions (not shown inFIG. 1 ) of differing heights, as will be described below in more detail with reference toFIGS. 4 to 6 . - Referring now to
FIG. 2 , there is shown a second embodiment of sole construction, generally indicated 20, according to the first aspect of the present invention, further comprising a second like skeleton sole 21, also referred to herein as a midsole. Themidsole 21 is of like formation to theinsole 11, being formed from layered carbon fibre composite material, presenting atop surface 22 and abottom surface 23, and comprising a raisedheel area 13, anarch area 14, lastingallowances 15,ribs 17, a heelpin mounting point 18, and aboundary area 19, all as hereinbefore described in relation to theinsole 11. The particular example of the second skeleton sole 21 shown inFIG. 2 lacks aforefoot area 12 and recesses 16 in itstop surface 22, though it should be understood that these features may be present in other embodiments of thesecond skeleton sole 21. - The
midsole 21 is adapted to underlie theinsole 11 and engage therewith. To that end, although not visible inFIG. 2 , thebottom surface 23 of theinsole 11 follows the profile of thetop surface 22, such that recesses (not visible inFIG. 2 ) are effectively formed in thebottom surface 23 of theinsole 11, corresponding to the location of theribs 17 in thetop surface 22 thereof. Theribs 17 on thetop surface 22 of themidsole 21 thus engage with the recesses in the bottom surface of theinsole 11 when theinsole 11 overlies themidsole 21. When mated in this arrangement, themidsole 21 andinsole 11 effectively act as singlesole construction component 20. - Referring now to
FIG. 3 , there is shown an alternative embodiment ofmidsole 24 for use in thesole construction 20 ofFIG. 2 . In this embodiment, the carbon fibre compositesecond skeleton sole 21 comprises aheel area 13 only. The remainder of themidsole 24 is thus made up by conventional materials such as leather, thermoplastic polyurethane (TPU) or rubber. - Referring now to
FIGS. 4 to 6 , there is shown asole construction 20 according to the first aspect of the present invention, as described above with reference toFIG. 2 , in combination with a range ofheel constructions sole construction 20 shown inFIGS. 4 to 6 , themidsole 21 features aforefoot area 12, unlike the example shown inFIG. 2 . - A
heel pin 31, formed of titanium, stainless steel, a hardened steel alloy, or other high tensile strength material is secured to the heelpin mounting point 18 on thesole construction 20 by means of a low profile screw (not shown inFIGS. 4 to 6 ). Theheel pin 31 extends from anut 32, which is of complementary shape to the heelpin mounting point 18, to atip 33 at the lower end thereof. Theheel pin 31 is further provided with a spring-loadedplunger element 34, the operation of which is described in the inventors EP 3,122,199. Theheel pin 31 as hereinbefore described is intended to be permanently secured to thesole construction 20. A range ofheel constructions heel pin 31. - Referring first to
FIG. 4 , there is shown the engagement of thesole construction 20 with a first heel construction, generally indicated 30, corresponding to a heel height of 60-70 mm. Theheel construction 30 comprises aheel profile 35, which constitutes the externally visible part of theheel construction 30. The top end of theheel profile 35 houses aheel insert 36, whilst arod 37 extends through the main body of theheel profile 35 and retains in place acap 38 having an upstanding peg (not shown) which engages with a complementary hole (not shown) in the bottom of therod 37. - The
heel pin 31 engages with theheel insert 36 in an interference fit; theplunger 34 engages with a recess (not shown inFIG. 4 ) in theheel insert 36 for added security. Theheel pin tip 33 also engages in an interference fit with a machined hole (not shown inFIG. 4 ) in the top of therod 37. Therod 37 is key to achieving the required structural strength. Load during gait is transferred from thesole construction 20 via theheel pin 31 to therod 37. Proper engagement theheel pin tip 33 with therod 37 is essential to avoid theheel profile 35 breaking. - As can be seen from
FIG. 4 , in order for theheel construction 30 to be presented in its normal configuration for use in this first embodiment of high heel shoe, therod 37 is arranged vertically, as indicated by line a, theheel pin 31 must be presented to engage with theheel insert 36 at an angle offset from the vertical, as indicated by line b. That is to say, the angle x between the horizontal c, taken from underneath thesole construction 20, and the line of approach b of theheel pin 31 is greater than 90°. The line of approach b and angle x are determined by the shape and construction of theheel profile 35 and the orientation of theheel insert 36 therein. - As can be seen in
FIG. 4 , in order to adopt the correct line of approach b for theheel pin 31 to engage with theheel profile 35, the sole construction must effectively be rotated from the horizontal c about a rotation point d at or adjacent theboundary areas 19 such that theforefoot areas 12 are elevated relative thereto. However in use, the body weight of the wearer, as indicated at e, will urge theforefoot areas 12 back towards the horizontal c, rotating them around the rotation point d and causing thesole construction 20 to flex at theboundary areas 19. - The
rod 37 preferably has a non circular cross section, so that it can be rotationally positioned by reference to its cross section, so that the angle of the machined hole in therod 37 is matched to the angle of theheel pin 31 at that particular heel height during placement of therod 37 in theheel construction 30. - Referring now to
FIG. 5 , there is shown the engagement of thesole construction 20 with a second heel construction, generally indicated 40, corresponding to a heel height of 80 mm. Thesecond heel construction 40 comprises aheel profile 45, and has aheel insert 36,rod 37, andcap 38, as hereinbefore described with reference toFIG. 4 . The engagement of theheel pin 31 with theheel construction 40 is also otherwise as hereinbefore described with reference toFIG. 4 . - However, in view of the increased height of the
second heel construction 40 relative to thefirst heel construction 30 described above with reference toFIG. 4 , theheel insert 36 is oriented differently in theheel profile 45. With theheel profile 45 presented in its normal configuration for use in the first embodiment of high heel shoe, i.e. with therod 37 arranged vertically, as indicated by line a, theheel pin 31 is now presented to engage with theheel insert 36 at an approach angle b substantially aligned with the vertical. That is to say, the angle x between the horizontal c, taken from underneath thesole construction 20, and the line of approach b of theheel pin 31 is substantially 90°. Theforefoot areas 12 are thus generally horizontally disposed, and thesole construction 20 is effectively in a neutral configuration with substantially no flexing. - The
rod 37 preferably has either has a non circular cross section, or theheel pin 31 could engage in a machined hole directly at the center of therod 37, which does not require any rotational positioning. - Referring now to
FIG. 6 , there is shown the engagement of thesole construction 20 with a third heel construction, generally indicated 50, corresponding to a heel height of 100 mm. Thethird heel construction 50 comprises aheel profile 55, and has aheel insert 36,rod 37, andcap 38, as hereinbefore described with reference toFIG. 4 . The engagement of theheel pin 31 with theheel construction 50 is also otherwise as hereinbefore described with reference toFIG. 4 . - However, in view of the further increased height of the
third heel construction 50 relative to the first andsecond heel constructions FIGS. 4 and 5 , theheel insert 36 is oriented differently again in theheel profile 55. With theheel profile 55 presented in its normal configuration for use in the first embodiment of high heel shoe, i.e. with therod 37 arranged vertically, as indicated by line a, theheel pin 31 is now presented to engage with theheel insert 36 at an approach angle b offset from the vertical, but in the opposite direction to that described above with reference toFIG. 4 . That is to say, the angle x between the horizontal c, taken from underneath thesole construction 20, and the line of approach b of theheel pin 31 is now less than 90°. - As can be seen in
FIG. 6 , in order to adopt the correct line of approach b for theheel pin 31 to engage with theheel profile 55, thesole construction 20 must again effectively be rotated from the horizontal c about the rotation point d at or adjacent theboundary areas 19, but in the opposite direction to that described above with reference toFIG. 4 , such that theforefoot areas 12 are now depressed relative thereto. However in use, theforefoot areas 12 will be urged back towards the horizontal c, by impact with the ground, as indicated by arrow e, rotating them around the rotation point d and causing thesole construction 20 to flex at theboundary areas 19. - The
rod 37 preferably has a non circular cross section, so that it can be rotationally positioned by reference to its cross section. The angle of the machined hole is matched to the angle of theheel pin 31 at that particular heel height during placement of therod 37 in theheel construction 50. - Referring now to
FIG. 7 , there is shown the engagement of thesole construction 20 with aheel construction 80, for use in a second embodiment of high heel shoe in which therod 37 is aligned with theheel pin 31. Theheel construction 70 shown inFIG. 7 corresponds to a heel height of 95 mm. - The
heel pin 31 preferably engages in a machined hole directly at the center of therod 37. Therod 37 preferably has one or more non circular side surfaces, so that it can be positioned within theheel construction 70 at the rotational position at which its bottom surface is parallel to the ground, and is matched during placement of therod 37 in theheel construction 70. - Referring now to
FIG. 8 , there is shown the engagement of thesole construction 20 with aheel construction 80, for use in a third embodiment of high heel shoe in which therod 37 is disposed at an angle from the vertical, mirroring that of theheel pin 31. Theheel construction 80 shown inFIG. 8 corresponds to a heel height of 100 mm. - The
rod 37 can in principle be disposed at any angle, for more versatility in designing heel constructions, but the machined hole in therod 37 for engagement ofheel pin 31 must always follows the angle of theheel pin 31. - The
rod 37 preferably has a non circular cross section, so that it can be rotationally positioned within theheel construction 80. This enables the angle at which the bottom surface of therod 37 is parallel to the ground to be matched during placement of therod 37 in theheel construction 80. The angle of the machined hole is also matched to the angle of theheel pin 31 at that particular heel height during placement of therod 37 in theheel construction 80. Referring now toFIGS. 9 to 12 , there is shown a high heel shoe, generally indicated 60, according to a second aspect of the present invention. Theshoe 60 is formed around asole construction 10, and further comprises an upper 61, anoutsole 62, and aheel construction 70 affixed by ascrew 41. For ease of reference, thehigh heel shoe 60 is shown inFIGS. 9 to 12 with a first embodiment ofsole construction 10 as described above with reference toFIG. 1 , having a first skeleton sole (insole) 11 only, and with astandard heel construction 70, rather than the interchangeable heel constructions described above with reference toFIGS. 4 to 6 , though it should be appreciated that the features of thehigh heel shoe 60 described below with reference toFIGS. 9 to 12 also apply to other combinations of sole construction and heel construction. - With reference to
FIG. 12 , the enhanced strength of thesole construction 10 enables theshoe 60 to be constructed with asingle screw 41 passing through the mountingpoint 18, and into theheel construction 70. Additional peripheral screws may also be utilised if desired. - As can best be seen in
FIG. 10 , the upper 61 is secured to thebottom surface 23 of theinsole 11, by being received in thelasting allowances 15. The depth of thelasting allowances 15 are substantially equal to the thickness of the upper 61 so as to present a substantially flush surface for attachment of theoutsole 62. The upper 61 is secured to theinsole 11 in theheel area 13 by gluing, the glue being applied directly to thebottom surface 23 of theinsole 11, and to the upper 61 prior to and/or during the lasting process. The upper 61 is further secured to theinsole 11 by means ofnails 42. Theoutsole 62 has acentral rib 63 adapted to be received in a recess formed in thebottom surface 23 of theinsole 11 corresponding to the location of thecentral rib 17 on thetop surface 22 of theinsole 11. - The formation of the skeleton sole 11 from carbon fibre composite material enables the thickness of the
sole construction 10 to be reduced without compromising strength or rigidity, and further obviates the need for a metal shank to be incorporated into thehigh heel shoe 60. This frees up space within theshoe 60 for the inclusion of afootbed 65 to be formed on top of thesole construction 10. - The
footbed 65 is formed from cushioning material, and can be constructed to a greater thickness than cushioning provided in conventional high heel shoes, in view of the additional space made available by reducing the thickness of thesole construction 10. This leads to greatly enhanced comfort for the wearer. - The
footbed 65 can includeinserts 66 of material adapted to provide further enhanced cushioning, additional wear resistance, or other desired properties as required. These may particularly be provided in theforefoot 12 andheel 13 areas, as shown inFIGS. 9, 11 and 12 . - Referring now to
FIGS. 13 to 16 , there is shown an exploded view of ahigh heel shoe 60 and cross sections along the lines A-B, C-D and E-F (when the components are assembled), according to a second aspect of the present invention. Theshoe 60 is formed around asole construction 10, and further comprises an upper 61, anoutsole 62, and aheel construction 40 having aheel profile 45 affixed by ascrew 41. - As can best be seen in
FIG. 14 , the upper 61 is secured to the bottom surface of theinsole 11 substantially the same as described inFIG. 1 , by being received in thelasting allowances 15. The depth of the recess is substantially equal to the thickness of the upper so as to present a flush surface with the recessed surface of theinsole 11 for attachment of theoutsole 62. - As can best be seen in
FIG. 15 , portions of the insole protrude from the recessed surface of the insole, such as the heel mountprotrusions 100 andrib protrusion 101. These are not covered by the upper 61 and remain exposed after lasting and cutting the excess lasting allowance leather. - Additional reinforcing
inserts 103, made out of hard material, that at least partially match the shape of the protruding area not covered by the upper 61, are placed on the underside of theinsole 11 and fill inheel mount protrusion 100 andrib protrusion 101 to create a completely flush surface for theoutsole 62. In some embodiments of the invention there is only a reinforcinginsert 103 in theheel mounting protrusion 100, and inothers reinforcing inserts 103 are placed in therib protrusion 101 of theinsole 11. - The reinforcing
insert 103 forheel mounting protrusion 100 enables screwing on astandard heel construction 40 for high heel shoes, and attaching astandard outsole 62 for high heel shoes, without any gaps remaining between the bottom surface of theinsole 11, and the top surface of theheel construction 40 andoutsole 62.
