FOOTWEAR

Background of the Invention The present invention relates to footwear, and in particular, to enclosed-style footwear in which the heel section may be at least partly detached from the toe section thereof, such that the footwear may be easily slipped on or off the foot of the wearer.

Description of the Prior Art The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that that prior art forms part of the common general knowledge in Australia.

In general, footwear may be described as being either sandal-style type or enclosedstyle. Conventional sandal-style footwear usually has a strap attached to the back to retain the sandal on a user's foot. Such sandal-style footwear is more readily slipped on or off the foot of a wearer, than enclosed-style footwear.

Enclosed-style footwear provides better support for the ankle and heel of the foot, due to the snug fit, with increased height of the footwear and a smaller foot opening.

Enclosed-style footwear, however, is generally characterised in that the foot opening 11, when installed on the foot of a wearer, is smaller than the wearer's foot. To place the footwear on or off the foot of the wearer, a fastening device is required, such that, when taking enclosed-style footwear on or off, the fastening device is undone. Such a fastening device is more traditionally a lace or buckle or zipper, but nowadays, often incorporates hook and loop fastening means (known as VelcroTM).

To place this enclosed-style footwear on, the fastening device must be undone. The foot is normally manoeuvred into the footwear by twisting the ankle such that the toes are initially pointed whilst the foot is inserted into the footwear, and then, again the heel is twisted and the foot is returned from the pointed position whilst pushing the wearer's heel into the heel section of the footwear. This sequence is necessitated in order to negotiate the P.\\VPDOCSIMD\Sp-r-wi i\1262927 dc.27 I-n 2X6 -2angle between the heel section and the shoe proper (front or toe part of the shoe). Once the toes and heel are both positioned into the footwear, the fastening means may then be fastened. Likewise, to take the footwear off, the reverse procedure is followed.

Whilst many persons are easily able to perform this task, some groups of persons have difficulty in placing on or taking off this enclosed-style footwear. Infants, small children, disabled or handicapped persons generally require assistance in doing this because they are unable or unknowing how to rotate their heels, point their toes, and apply the appropriate pressures to the toe and heel portions to ensure that the footwear is properly fitted.

This therefore identifies a need for a different or improved footwear which enable the various parts of the footwear to be at least partially detached, and to thereby enable the footwear to be slipped on or off more conveniently without the need for the usual type of rotation and force or pressure application to the foot of the wearer.

Summary of the Invention The present invention seeks to provide a footwear which overcomes the disadvantages of the prior art enclosed-style footwear.

Throughout this specification, the term shoe should be construed to encompass any type of footwear which is of an enclosed-style, as opposed to sandal-style. That is, it should be considered to encompass boots, runners and any like type of footwear.

Likewise, when the term enclosed-style footwear is used, this should be considered to encompass footwear which may not totally enclose the toes or heels, but rather, could be partly open, have holes, slits or like patterns cut out of the footwear, but would not be classified as sandal-style footwear.

The present invention seeks to provide a shoe having a toe section and a heel section, characterised in that said heel section is at least partly detachable from said toe section.

P kWPDOCSAMD\Spc3rK1onSI262927I doc.27 J 2006 -3- In one broad form, the present invention provides a shoe of the type having a c substantially flexible upper and a substantially firm sole, the shoe including: a toe section, including a forward sole portion and a forward upper portion (vamp); a heel section, including a rear sole portion and a rear upper portion (counter); S 5 an insole, of unitary construction, adapted to overlay both the forward and rear sole Sportions of said shoe; and detachable fastening means for releasably attaching said heel section to said toe section; such that, in use, said shoe may be installed on the foot of a wearer by: detaching the fastening means; twisting or removing said heel section relative to the toe section in a manner such that the rear sole portion is moved out of alignment relative to said forward sole portion of said shoe, whilst said insole is retained within said toe section of said shoe; slipping the toes of the wearer directly into said toe section from a rearward position to place the wearer's foot atop said insole; returning said heel section of said shoe into alignment with said toe section, about the heel of the wearer; and fastening the fastening means.

Detailed Description of Preferred Embodiments The known and generally accepted terminology in relation to footwear is initially described with reference to Figure 16.

Throughout this specification, the term "shoe" is used in the traditional sense, that is, defining that type of footwear which is used for walking or running, or the like, and which provides an outer covering for the human foot, which is shaped to fit the foot, typically below the ankle, having a flexible upper of leather or like synthetic material, and a more rigid firm sole with an attached heel portion.

PPDOSM pi~in"697~w2 J I 2X) -7- Also, throughout the specification and with reference to Figure 16, the "heel section" 3 is used to describe the rear part of the shoe which necessarily includes the portion of the sole 10 at the rear of the shoe with or without a "heel proper", together with the "counter" 11 and part of the "quarter" 12 of the upper portion of the shoe.

The "counter" 12 is the stiff part of the back of the shoe above the heel 10, which provides structured rigidity and thereby maintains integrity to the shoe by supporting the shoe upper. It thereby provides support to the back part of the foot, to distinguish a "shoe" from a sandal", which does not provide support to the ankle.

The "quarter" 12 is the back part of the upper, above the heel Likewise, throughout the specification, the "toe section" 2 is used to describe the front part of the shoe which includes the sole portion 13 at the front of the shoe, together with the forward upper part of the shoe, also known as the "vamp" 14.

These features of a shoe, and which are known to persons skilled in the art, are illustrated in Figure 16.

A first embodiment of a shoe in accordance with the present invention is illustrated in Figures 1 to 6. These Figures illustrate a shoe, generally designated by the numeral 1, having a toe section 2, and a heel section 3. It will be seen that the toe section 2 is attached to the heel section 3, by means of a fastening means, which in this embodiment is configured as a zipper 4. Figure 1 illustrates a view of the shoe 1 in the attached position, i.e. with the zipper 4 closed, looking from the outside of the shoe, whilst Figure 2 shows the same shoe from the inside view.

As illustrated in Figures 3, 4 and 5, the heel section 3 may be partly detached from the toe section 2, by undoing the zipper 4 or other fastening means. Once the fastening means 4 is undone, the heel section may then be twisted or rotated transversely out of the plane extending substantially vertically through a longitudinal direction of the shoe (in the P PDC\kMWrf- 691 dW2 hMc ZIM6 -8attached position) to the position shown in Figures 3, 4 and 5. It will be appreciated that once the heel section 3 is rotated relative to the toe section 2, the foot of a wearer may be easily inserted into the toe section 2, and then, the heel section 3 may be re-rotated to surround the rear of the wearer's foot. The fastening means 4 or other zipper, may then be done up to reattach the heel section 3 to the toe section 2.

It will be appreciated that the shoe of this embodiment may be easily installed on the foot of an infant, small child, invalid or disabled or handicapped person without difficulty, and the zipper 4 may be easily done up. This may all be done without the requirement for the wearer to have to bend, twist and apply pressure to their toes, ankle or other parts of their foot as they usually do when having to place their foot into a conventional enclosed type shoe.

It will be appreciated by persons skilled in the art that variations and modifications to the embodiment hereinbefore described may be made. Such variations and modifications should be considered to be within the scope of the invention as herein described.

For example, an alternative embodiment is illustrated in Figures 7 to 10, wherein the heel section 3 may be rotated downwardly relative to the toe section 2, as perhaps best illustrated in Figures 8 and 9. That is, in this case, the heel section 3 is again partly detached from the toe section 2 by undoing the zipper 4. The heel section 3 is this time rotated transversely relative to the plane extending substantially horizontally through a longitudinal direction of the shoe to the position shown in Figures 8 and 9. Figure 9 illustrates how an insole 5 will maintain its position in this embodiment, ensuring that the insole 5 still provides the required support once the shoe 1 is done up. As with the embodiment shown in Figures 1 to 6, the embodiment of Figures 7 and 10 is also able to be installed on the foot of the types of wearer hereinbefore described, without needing the wearer to have to bend, twist and apply pressure to their toes, ankle or other parts of their foot as per conventional enclosed-style footwear.

P. WPDOCS%.A Spmirimiom%1262927ldo)-.27 ioe 2 -9- The embodiment of Figures 7 to 9 also incorporates a fastening tab 6, forming part of the fastening means 4, in addition to the zipper.

It will be appreciated in that in yet a further embodiment, the heel section may be totally detached from the toe section, by incorporated a zipper which extends right around the mid section of the shoe, such as illustrated in Figures 11 to Figure 13 perhaps best illustrates a 'totally detachable' form of footwear, wherein it can be clearly seen that the zipper 4 or other fastening device extends entirely about the mid-section of the footwear, Figure 13(a) illustrating the toe-section 2, and Figure 13(b) illustrating the heel-section 3. Figures 14 and 15 illustrate details of this embodiment of the footwear, with Figure 14(a) showing the position of the midsole on the toe portion of the shoe upper, Figure 14(b) showing the position of the midsole heel on the heel-section of the shoe upper, Figure 15(a) illustrating a supportive contoured shank of the insole component of the shoe, and, Figure 15(b) showing a leather covered, padded overlay of the insole components of the shoe of this embodiment.

Whilst each of the embodiments hereinbefore described have shown the use of a zipper, and whilst the second embodiment hereinbefore described also incorporates a Velcro tab, it will be appreciated that the attachment and detachment of the heel section from the toe section of the shoe may be facilitated by a variety of fastening means. Such fastening means may include one or more zippers, hook and loop fastening means (known as Velcro T M tabs or overlay, press stud, buckle, lace, or any combination of the above.

Other fastening means which are known or become apparent to persons skilled in the art should also be considered to be incorporated within the scope of this invention.

It should also be noted that, depending on the embodiment implemented, alteration of the soles is inherent from those of conventional footwear. In particular, it will be noted that the external sole will either be constructed in two separate parts, as per the first and third embodiments hereinbefore described, or, in one part which permits it to bend or fold downwards, as per the second described embodiment. It will also be noted that the inner P:\WPDOCSAMD SpmCifioI s126292"1 doc-27 June 2 M6 sole (insole) may, in any of these described embodiments, still be of unitary construction and be attached to the toe section 2 of the shoe. This unitary construction enables better support to the foot of the wearer than if constructed in two parts.

It should also be noted that, with the external sole constructed in the manner hereinbefore described, and with the inner sole also constructed in a manner such that it can also easily fold or be flexible, the wearer will be able to flex his ankle forward more readily than in conventional shoes, whilst still being supported. This may have improved performance in certain applications, for instance, in certain sports. That is, with the soles virtually hinged, the heel will not lift out of the shoe as it typically does when walking fast or running in conventional shoes.

It will also be appreciated that the shoe of the present invention may be constructed of a variety of materials. Suitable materials include leather, plastics, textiles, rubber, synthetic materials, and the like. It will be appreciated that there should be no limitation to the type of material which is utilised for constructing this shoe. That is, all suitable materials known to persons skilled in the art to be used for constructing footwear should be incorporated within the scope of the present invention.

As hereinbefore mentioned, the shoe of the present invention is particularly useful for infants, small children, disabled, handicapped, invalid persons, or persons with a foot injury, who might typically have difficulty in bending their foot as required to put on a conventional type enclosed shoe. However, the shoe may be conveniently utilised by any person, whether they have this physical limitation, or not. The shoe may also be utilised by sporting persons requiring the flexibility inherent in the design/features of the shoe of the present invention.

The shoe of the present invention therefore provides good ankle support whilst retaining the smaller opening of a conventional enclosed-style shoe, but has the advantage that it is easily fitted without twisting, turning or otherwise applying force to insert or remove the shoe from the foot of the wearer. It enables the wearing of a shoe with P \WPDOCSAMDSlcinfclio1u2629271 do 21 Jun 2006 11 provision of needed ankle support for people who would not otherwise be able to wear a suitable shoe with such ankle support.

It will also be appreciated that the shoe of the present invention may incorporate traditional arch supports, insole supports and ankle supports, as per conventional type shoes, to achieve the usual purposes known to persons skilled in the art.

All further variations and modifications of the present invention which become apparent to persons skilled in the art, should be considered to be encompassed within the scope of the invention hereinbefore described.
