Description

    FIELD OF THE INVENTION
  • The invention relates generally to removable insoles for shoes which help to boost the apparent height of the wearer.
  • BACKGROUND OF THE INVENTION
  • Removable shoe insoles for increasing the apparent height of the wearer are well known in the marketplace. These insoles generally consist of a wedge shaped member which is thicker at a back end and which gradually tapers to a front end. The insole is inserted into the shoe with the thicker end placed on top of the heel portion of the insole of the shoe. The thicker end of the insole acts as a support for the heel. By placing the heel of the wearer's foot on the heel portion of the insole, the wearer's apparent height is increased by the thickness of the heel portion of the insole.
  • Prior art removable insoles suffer from several problems. Firstly, they have a tendency to slip within the shoe, causing the wearer to feel uncomfortable and unsteady while walking. This is particularly a concern when the heel portion of the insole is higher. Furthemore, the thickness of the heel portion of the insert tends to cause injury to the users foot as a result of the build up of pressure on the heel portion of the foot. This makes the wearing of these insoles uncomfortable and may lead to an increased likelihood of tripping, falling or foot fatigue. An improved insole which overcomes these difficulties is therefore desirable.
  • SUMMARY OF THE INVENTION
  • In accordance with one aspect of the present invention, there is provided a removable insole liner for a shoe. The insole includes an integrally formed wedge shaped member having opposite back and front ends, a top surface and a bottom surface, the wedge shaped member having a base layer towards the bottom surface, a top layer towards the top surface and a middle layer interposed between the base and top layers. The base layer is formed from polyurethane infused with particles of natural cork, the middle layer is formed from silicone gel, and the top layer is formed from memory foam, with the upper layer and base layer being integrally bonded to the middle layer. The base layer has a thickness which tapers from 2.5 cm from the back end of the wedged shaped member to 0.4 mm at the front end of the wedged shaped member, the middle layer has a thickness which tapers from 0.7 cm from the back end of the wedged shaped member to 0.6 mm at the front end of the wedge shaped member, and the top layer has a uniform thickness of 6 mm from the back end of the wedge shaped member to the front end of the wedge shaped member. Finally, the bottom surface has a plurality of projecting ridges.
  • In accordance with another aspect of the present invention, there is provided a removable insole liner for a shoe which includes an integrally formed wedge shaped member having opposite back and front ends, a top surface and a bottom surface, the wedge shaped member having a base layer towards the bottom surface, a top layer towards the top surface and a middle layer interposed between the base and top layers. The base layer is formed from a polyurethane plastic, the middle layer is formed from silicone gel, and the top layer is formed from memory foam, the upper layer and base layer being integrally bonded to the middle layer. The base layer has a thickness which tapers from 2.5 cm from the back end of the wedged shaped member to 0.4 mm at the front end of the wedged shaped member, the middle layer has a thickness which tapers from 0.7 cm from the back end of the wedged shaped member to 0.6 mm at the front end of the wedge shaped member, the top layer has a uniform thickness of 6 mm from the back end of the wedge shaped member to the front end of the wedge shaped member. The base layer has a composition configured to give the base layer a shore hardness which progressively decreases from the back end of the wedge shaped member to the front end of the wedge shaped member and wherein the middle layer has a composition configured to give the middle a shore hardness which progressively increases from the back end of the wedge shaped member to the front end of the wedge shaped member and wherein the top layer is configured to have a substantially uniform shore hardness. Finally, the bottom surface has a plurality of projecting ridges.

  • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIGS. 1, a shoe insole insert made in accordance with the present invention is shown generally as item 10 and consists of a wedge shaped member 12 having back end 14 and front end 16, bottom surface 18 and top surface 20. Member 12 consists of a three layered structure having base layer 22, middle layer 24 and top layer 26. The three layers are integrally formed and firmly bonded together so that there is no possibility of slippage between the layers. The thickness of back end 14 of member 10 is determined by the desired lift in the height of the person intending to wear the insole insert. Ideally, the thickness of back end 14 is approximately 4 cm or so, although it can be a little greater or a little thinner as desired. Base layer 22 tapers in thickness from approximately 2.5 cm at back end 14 to approximately 0.4 mm at the front end 16. Of course, the exact thicknesses of each layer (and of member 12 as a whole) can be preselected depending on the desired height of the insole insert. Middle layer 24 also tapers in thickness from 0.7 cm at back end 14 to 0.6 mm at front end 16. Again, the exact thickness of middle layer 24 can be preselected as required. The thickness of top layer 26 remains substantially uniform from back end 14 to front end 16, preferably in the range of 0.6 mm.
  • The hardness and “firmness” of the component parts of wedge shaped member 12 can be measured using a durometer to obtain a shore hardness. The shore A hardness is a measure of how hard or flexible molded rubber (natural or synthetic) products can be from very soft and pliable to very stiff and almost no flexibility. The relative shore A hardness of the different layers and how that hardness changes from the back of the insert to the front of the insert is a key aspect of the present invention. The base layer is made of a polymer material and is manufactured such that the shore A hardness of the base member decreases from back end 14 to front end 16. Preferably, the composition of base layer 22 is selected such that the base layer has a shore hardness of 55 A at end 14 and a shore hardness of 35 A at end 16. Middle layer 24 is made of silicone gel and increases in shore hardness from back end 14 towards front end 16. In particular, the shore hardness of middle layer 24 increases from 3 A at end 14 to 7 A at end 16. Top layer 26 is preferably made from memory foam and has a uniform hardness from end 14 to end 16 of between about 7 A to about 9 A. Therefore, the base layer and middle layer have opposite hardness profiles, making the base layer harder at the back end (where the user's heel will rest) and softer at the front end, while the middle layer will be softer at the back end yet harder at the front end. This permits the base layer to provide a firmer base for the user's heel while allowing the middle layer to provide more force dampening at that point. This maximizes comfort while at the same time providing a secure footing for the user's heel.
  • The base layer is made of polyurethane with up to 10% cork by volume. It has been discovered that polyurethane, by itself, for constructing the base layer leads to a finished product which is too hard to be worn comfortably for long periods of time. The elevated heel portion of the insole insert 10 (i.e. back portion 14) bares a great deal of weight when the user wears the insert inside his/her shoes. As a result, increasing the hardness of the heel portion can result in increased foot strain. The hardness of the base layer is an important factor in the overall comfort and usability of the shoe insole insert. It has been discovered that adding between 1% to 10% cork particles to the composition of the base layer decreases the hardness of the base layer sufficiently to produce an insert which is sufficiently firm to provide good support while providing increased comfort.
  • As seen in FIG. 4, the bottom surface 18 of the base layer is provided with a plurality of projections , such as ridges in a cross hatched pattern. These cross hatched ridges help the base of the insert to seat itself securely in the shoe and prevents the base layer from slipping against the shoe's insert. The raised projections (ridges) increases the frictional contact between the insole of the shoe and the bottom of the base layer, resulting in a firmer more secure footing for the user's foot. Any pattern of raised projections can be used, but a cross hatched pattern of ridges is best because it increases friction in any direction.
  • Referring now to FIGS. 2 and 3, as the user applies his/her weight via heel 28 onto member 12 of insole insert 10, top layer 26 and middle layer 24 deform slightly while base layer 22 does not deform (relatively speaking). As the user walks, heel 28 bares down hard onto back end 14 as the foot touches the ground/floor. Middle layer 24, being less hard then base layer 22 deforms and therefore absorbs much of the shock; however, the portion of middle layer 24 closest to back end 14 deforms the most exactly where the impact forces are greatest. The forward portion 30 of the foot in front of heel 28 then receives more weight as the user moves forward in the step. It has been discovered that the changing shore hardness profiles of the middle and base layers make for a much improved and more comfortable step. The base layer, being stiffer towards the back end 14 provides a firmer and more secure connection to the sole 32 of shoe 34 where the impact of the foot (i.e. the heel) is greatest. This effectively transfers more energy from the heel of the foot to the sole of the shoe and provides greater stability. The portion of the base layer closer to end 16 is softer and more flexible, thereby allowing the base layer to flex more easily at the front thereby preventing the front end of the insert from buckling or dislodging from the shoe, resulting in a more secure step. The base, middle and top layers, all being intimately and securely bonded to each other prevents the top and middle layers from shifting from side to side relative to base layer 22, also keeping the foot centered on top of the insert and decreasing the likelihood that the position of the foot on the insert will shift from side to side. This makes the insert more comfortable to walk with.
  • A specific embodiment of the present invention has been disclosed; however, several variations of the disclosed embodiment could be envisioned as within the scope of this invention. It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims
