Definitions
- the invention relates to an insole to be used with a shoe, and a method of Strobel lasting a shoe.
- the safety shoe is subjected to an automated test where a nail is pressed against an insole of the safety shoe to test whether the insole is capable of withstanding a nail pressure of about 1.1 kN without the nail penetrating the insole.
- the insole is manufactured from a fibrous material, such as a thermoplastic, and needs to be at least partially flexible where the wearer's mid foot ends and the front foot begins, since the insole should follow the outline of the wearer's foot when the wearer is waling or running.
- a problem is that a flexible material capable of withstanding the nail pressure test discussed above is expensive.
- Materials withstanding such pressure include for instance Kevlar, Dyneema and Dyproflex.
- the shankboard is rigid and stiff for providing stability to the wearer's foot and may for instance be manufactured from a plastic material. Hence, by applying a shankboard to the insole, a flexible material being capable of withstanding the nail pressure test is only required at the front foot section of the insole in front of the shankboard.
- the single most common method of attaching an insole to an upper of a shoe before an outsole is mounted to the insole is the so called Strobel method.
- Strobel method the insole is stitched the upper, which is commonly referred to as lasting. Thereafter, the outsole is permanently attached to the insole, and the shoe is complete.
- An object of the present invention is to solve, or at least mitigate, the above given problem and thus provide an improved insole to be used with a shoe.

- the shankboard is arranged to extend in a radial direction over a surface of the insole and end about 5 mm from the periphery of the insole.
- Standard piercing-resistance requirements stipulate that the insole must be piercing-resistant on a surface of the insole starting not more than 6 mm from the periphery. This embodiment advantageously ensures that these requirements are satisfied.
- the insole comprises a piercing-resistant member being attached to an underside of the insole at a section of the insole where the shankboard ends, i.e. at the front foot section.

Abstract
Description
- The invention relates to an insole to be used with a shoe, and a method of Strobel lasting a shoe.
- Shoes used in industrial environments, commonly referred to as safety shoes, must undergo demanding tests during to assure that the shoes comply with strict safety and endurance requirements.
- As an example, the safety shoe is subjected to an automated test where a nail is pressed against an insole of the safety shoe to test whether the insole is capable of withstanding a nail pressure of about 1.1 kN without the nail penetrating the insole.
- The insole is manufactured from a fibrous material, such as a thermoplastic, and needs to be at least partially flexible where the wearer's mid foot ends and the front foot begins, since the insole should follow the outline of the wearer's foot when the wearer is waling or running.
- A problem is that a flexible material capable of withstanding the nail pressure test discussed above is expensive. Materials withstanding such pressure include for instance Kevlar, Dyneema and Dyproflex.
- An alternative to using these expensive materials for completely covering an underside of the insole in order to make the insole capable of withstanding the nail pressure test is to apply a so called shankboard (also referred to as a gelenk) to a section of the insole extending from the heel section over the mid foot section and ending where the mid foot section meets the front foot section.
- The shankboard is rigid and stiff for providing stability to the wearer's foot and may for instance be manufactured from a plastic material. Hence, by applying a shankboard to the insole, a flexible material being capable of withstanding the nail pressure test is only required at the front foot section of the insole in front of the shankboard.
- The single most common method of attaching an insole to an upper of a shoe before an outsole is mounted to the insole is the so called Strobel method. With the Strobel method the insole is stitched the upper, which is commonly referred to as lasting. Thereafter, the outsole is permanently attached to the insole, and the shoe is complete.
- However, the Strobel method cannot by used with prior art shankboards as these shankboards are rigid and extends along the full width of the insole and thus cannot be stitched the upper. Being the most common used method when manufacturing shoes, this is a problem since the existing Strobel production lines cannot be utilized for this purpose.
- An object of the present invention is to solve, or at least mitigate, the above given problem and thus provide an improved insole to be used with a shoe.
- This object is attained in a first aspect of the invention by an insole to be used with a shoe, the insole comprising a shankboard being attached to the insole, the shankboard being arranged to partially extend over a surface of the insole leaving a section along a periphery of the insole free, thereby enabling Strobel lasting of the insole to an upper of the shoe.
- This object is attained in a second aspect of the invention by a method of Strobel lasting a shoe. The method comprises attaching a shankboard to an insole, the shankboard being arranged to partially extend over a surface of the insole leaving a section along a periphery of the insole free, and stitching the insole to an upper of the shoe along the periphery of the insole.
- Advantageously, by leaving a section of the insole free along the periphery of the insole, the insole can be stitched to an upper along its periphery.
- In an embodiment of the invention, the shankboard is arranged to extend in a radial direction over a surface of the insole and end about 5 mm from the periphery of the insole. Standard piercing-resistance requirements stipulate that the insole must be piercing-resistant on a surface of the insole starting not more than 6 mm from the periphery. This embodiment advantageously ensures that these requirements are satisfied.
- In yet an embodiment, the insole comprises a piercing-resistant member being attached to an underside of the insole at a section of the insole where the shankboard ends, i.e. at the front foot section. Alternatively, the front foot section of the insole is manufactured from piercing-resistant material, even though that would imply a more complex manufacturing procedure. Advantageously, by covering only a section of the insole with this piercing-resistant material, manufacturing cost of the insole may be greatly reduced, as these materials are expensive.
- In a further embodiment, the piercing-resistant member is arranged to overlap the shankboard at a section of the insole where the shankboard ends and the piercing-resistant member starts. Thus, any gap created between the shankboard and the piercing-resistant member - where a sharp object potentially could pierce the insole - is advantageously avoided.
- In an embodiment, the shankboard is manufactured from a material comprising one or more of plastic, leather or pressed cardboard, or any other appropriate rigid material.
- In an embodiment, the piercing-resistant member is manufactured from a material comprising one or more of Kevlar, Dyneema or Dyproflex, or any other appropriate material being both piercing-resistant and flexible.
- The objective stated in the above is further attained by a shoe comprising the insole.
- In a further embodiment, a shoe is manufactured using the Strobel lasting method of the second aspect of the invention, where the method further comprises attaching a midsole and/or outsole to the lasted upper.

Figure 1 illustrates asafety shoe insole 10 being subjected to a nail pressure test for testing piercing-resistance of theinsole 10. Thus, as previously has been discussed, anail 11 is pressed (using an automated procedure) against an under side of theinsole 10 to test whether the insole is capable of withstanding a nail pressure of about 1.1 - 1.2 kN without thenail 11 penetrating theinsole 10. - Previous requirements have advocated that the
nail 11 has a diameter of 4.5 mm tapering down to a diameter of 1 mm at its narrow end piercing theinsole 10. New requirements are even stricter and advocate that theinsole 10 should be able to withstand this pressure using anail 11 having a diameter of 3 mm and 1 mm at its narrow end piercing theinsole 10. - To withstand such a test, the
insole 10 must either be manufactured from a piercing-resistant material, or alternatively the piercing-resistant material is attached to an underside of theinsole 10. The material must further be flexible for allowing a wearer of a shoe (not shown) being equipped with theinsole 10 to flex her foot when walking or running. Materials being both piercing-resistant and flexible, e.g. Kevlar, Dyneema or Dyproflex, are expensive. -
Figure 2 illustrates a prior artsafety shoe insole 10 being arranged with a so calledshankboard 12 at a section of theinsole 10 extending from the heel section over the mid foot section and ending where the mid foot section meets the front foot section. - The
shankboard 12 is rigid and stiff for providing stability to the wearer's foot and may for instance be manufactured from leather, pressed cardboard, or a plastic material. Hence, by attaching theshankboard 12 to theinsole 10, a flexible material being capable of withstanding the nail pressure test is only required at the front foot section of theinsole 10, where theshankboard 12 ends. -
Figure 3 illustrates the use of the so called Strobel method for attaching theinsole 10 to an upper 13. With the Strobel method, theinsole 10 is stitched along itsperiphery 14 to the upper 13 before an outsole (not shown) is mounted to theinsole 10 and the upper 13 and the shoe is complete. - As previously has been described, a problem in the art is that the Strobel method cannot be used then the
insole 10 is to be equipped with ashankboard 12. -
Figure 4 illustrates aninsole 20 according to an embodiment of the invention. Theinsole 20 of the embodiment is equipped with ashankboard 21 being attached to an underside of theinsole 20. - The
shankboard 21 is advantageously arranged to extend over a surface of theinsole 20 leaving asection 22 along aperiphery 23 of theinsole 20 free, thereby enabling Strobel lasting of theinsole 20 to an upper (not shown) for manufacturing a safety shoe, -
Figure 5 illustrates theinsole 20 of an embodiment having being stitched to an upper 24 along theperiphery 23 of theinsole 20. Thefree section 22 enables stitching of theinsole 20 to the upper 24 along thecomplete periphery 23 of theinsole 20. - In an embodiment of the invention, the
shankboard 21 is arranged to extend in a radial direction over the surface of theinsole 20 and end about 5 mm from theperiphery 23 of the insole. Standard piercing-resistance requirements stipulate that theinsole 20 must be piercing-resistant on a surface of theinsole 20 starting not more than 6 mm from theperiphery 23. This embodiment advantageously ensures that these requirements are satisfied. -
Figure 6 illustrates yet a further embodiment, where theinsole 20 comprises a piercing-resistant member 25 being attached to an underside of theinsole 20 at a section of the insole where theshankboard 21 ends, i.e. at the front foot section. Alternatively, the front foot section of theinsole 20 is manufactured from piercing-resistant material, even though that would imply a more complex manufacturing procedure. - Further with reference to
Figure 6 , in an embodiment, the piercing-resistant member 25 is advantageously arranged to overlap theshankboard 21 at a section of theinsole 20 where theshankboard 21 ends and the piercing-resistant member 25 starts. Thus, any gap created between the shankboard 21 and the piercing-resistant member 25 - where a sharp object potentially could pierce the insole 20 - is avoided. - In an embodiment, the
shankboard 21 is manufactured from a material comprising one or more of plastic, leather or pressed cardboard, or any other appropriate rigid material. - In an embodiment, the piercing-
resistant member 25 is manufactured from a material comprising one or more of Kevlar, Dyneema or Dyproflex, or any other appropriate material being both piercing-resistant and flexible. -
Figure 7 illustrates a shoe 30 comprising theinsole 20 according to embodiments of the invention. Hence, theinsole 20 is arranged with ashankboard 21 and potentially also a piercing-resistant member 25. Theinsole 20 is stitched to the upper 24 of the shoe 30 using Strobel lasting as previously has been discussed. Athin inlay sole 31 is placed on top of theinsole 20. The underside of theinsole 20 is enclosed by amidsole 32 of the shoe, which further may be arranged with anoutsole 33. -
Figure 8 illustrates a flowchart of a method of Strobel lasting a shoe according to an embodiment. The method comprises, in step S101, attaching ashankboard 21 to aninsole 20, theshankboard 20 being arranged to partially extend over a surface of theinsole 20 leaving asection 22 along aperiphery 23 of theinsole 20 free. Thereafter, in step S102, theinsole 20 is stitched to an upper 24 of the shoe along theperiphery 23 of theinsole 20. After these steps have been undertaken, an outsole ormidsole 32 can be attached to the lasted upper 24. - The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
