Definitions

  • the present invention relates to a footwear sole component, particularly, though not exclusively, an insole for an article of footwear and to an article of footwear comprising such a sole component.
  • footwear including "closed” footwear such as, for example, boots, shoes and trainers.
  • Articles of closed footwear have an upper lasted to a sole to form a foot chamber arranged to accommodate a users foot.
  • the sole itself can be of a number of constructions but always comprises an outer sole having an outer surface arranged to contact the ground. In the most basic articles of footwear the upper is lasted to this and a user's foot contacts an inner surface of the outer sole. More normally an article of footwear further comprises an insole arranged to sit between the outer sole and a user's foot. Such an insole may be integrally formed with the article of footwear or may be removable therefrom.
  • Articles of footwear may also comprise a mid sole interposed between the insole and outer sole. Soles can thus have a sandwich structure.
  • underbeds or undersoles
  • insoles for articles of footwear which can be inserted below an insole to provide another layer to the sole structure.
  • closed articles of footwear provide a foot chamber which can be prone to become hot and/or sweaty in use. This can be a particular problem in hot environments, when a wearer exercises, or if the wearer is prone to perspire excessively.
  • a foot chamber becomes hot and/or sweaty it can create several problems for a wearer.
  • a wearer may experience discomfort as a result of the heat and/or damp environment in which their foot is accommodated.
  • the conditions within the foot chamber may promote bacterial and/or fungal activity and may result in increased creation of malodours and/or skin infections. After use the footwear may retain the malodours and this can be unpleasant for those around the footwear.
  • breathable materials have been employed in the uppers of articles of footwear to improve the ventilation of a wearer's foot and allow egress of perspiration from the foot chamber.
  • GB 2382017 discloses an under-foot layer which can be an insole, footbed, or mid sole which comprises a plurality of air flow channels arranged to convey air to a ball/toe portion from a portion of the layer remote therefrom via a branched flow path.
  • the under-foot layer must have at least one channel which is connectable to a pump located in the heel for causing conveyance of the air. The pump can thus complicate the construction of an article of footwear employing such an under-foot layer and consequently employing the under-foot layer may be undesirably costly.
  • the present invention aims to address at least one disadvantage associated with known articles of footwear whether discussed herein or otherwise.
  • a footwear sole component comprising a toe portion and a heel portion connected by an arch portion, the sole component being arranged, in use, to form a part of a sole of a closed article of footwear having a foot chamber
  • the sole component comprises at least one compressible passage extending between a first portion of the sole component and a second portion of the sole component, which passage is arranged, in use, to have an opening into a first region of the foot chamber and an opening into a second region of the foot chamber such that air can be caused to travel from said passage into a second region of the foot chamber, by a pumping effect caused by compression of the passageway along at least a part of its extent during a stage of a wearers walking cycle.
  • the sole component is arranged such that, in use, air can be caused to travel from the first region of the foot chamber to the second region via at least one passage therein.
  • the sole component may be provided as a component of an article of footwear.
  • the sole component may comprise a removable component of an article of footwear.
  • the sole component may comprise an integral part of an article of footwear.
  • the sole component may be provided as a retro-fit component for a user to add to an article of footwear.
  • the sole component can be employed in any type of shoe, boot or trainer.
  • the sole component may comprise an insole.
  • the insole comprises a removable insole.
  • the insole may be transferable between articles of footwear.
  • the sole component may comprise an underbed, or a part of a midsole, arranged to lie immediately below an insole.
  • the sole component comprises an underbed or part of a midsole
  • an insole under which it lies will consist of a thin flexible sheet member.
  • the insole will be porous and/or have apertures to allow the first and second regions of the foot chamber to be in communication with the openings of one or more passages of the sole component.
  • the sole component comprises a plurality of passages.
  • the sole component may comprise at least 3 passages, preferably at least 5 passages, more preferably at least 20 passages, for example around 30 passages.
  • Each passage may thus transport air independently of the others.
  • one or more of said passages is resiliently deformable.
  • each passage is compressible.
  • a plurality of passages are arranged, in use, to be compressed for at least part of their extent during a stage of a wearer's walking cycle.
  • Each passage may be arranged, in use, to be compressed for at least part of its extent during a stage of a wearers walking cycle.
  • at least one of the or each passage is arranged to be compressed by the weight of a part of a wearer's foot acting on the passage during a stage of the wearers walking cycle.
  • each passage is arranged to be compressed in this manner.
  • each passage is resiliently deformable.
  • each passage is resiliently deformable and arranged, in use, to serve as an active pumping means for causing conveyance of air rather than as a passive conduit which simply carries air.
  • the sole component consists essentially of resiliently deformable passages and means, such as tube walls, defining said passages.
  • the sole component does not comprise any pumping means in addition to the one or more passages.
  • the sole component can be employed in an article of footwear which does not comprise any additional pumping means.
  • the sole component does not comprise any cavities or chambers in communication with said passage or passages.
  • said passage or passages do not comprise any enlarged portions which would serve as cavities or chambers. The sole component may thus not rely on the compression of a chamber or cavity to pump air in a bellows pump type action. Instead, movement of air through the sole component may be caused by progressive compression of passages of the sole component.
  • the sole component does not contain valves.
  • the first portion of the sole component comprises the heel portion thereof.
  • the first portion comprises a peripheral edge of the heel portion.
  • the second portion of the sole component comprises the toe portion thereof.
  • the second portion comprises a peripheral edge of the toe portion.
  • the first region of the foot chamber accommodates the wearer's heel.
  • the second region of the foot chamber accommodates the wearer's toes.
  • the sole component is arranged, in use, to suck air in at the heel and transmit it to the toes. After expulsion from the sole component at the toes the air may then travel over the top of the foot toward the heel.
  • the sole component may be such that, in use, it substantially neither draws in air or expels air from areas other than the heel and toe regions.
  • At least one of the or each passage of the sole component extends longitudinally, the longitudinal direction being from heel to toe.
  • each passage of the sole component extends longitudinally.
  • At least one passage is arranged to be compressible throughout its longitudinal extent.
  • each passage is arranged to be compressible throughout its longitudinal extent.
  • the or each passage may thus be able to provide an active pumping action when compressed at any point along its longitudinal extent.
  • substantially any part of the sole component may act as a pump independently of the rest. The sole component may thus not require a force to be applied at a specific pump area to produce a pumping effect. For example, even if a user walked only on the balls of their feet there would still be a pumping effect.
  • one or more passages extend from the heel portion to the toe portion.
  • one or more passages extend between peripheral edges of the heel and toe portion.
  • At least one passage has a cross-sectional area of between 0.1 mm 2 and 15 mm 2 , for example between 0.5 mm 2 and 5 mm 2 .
  • each passage has a cross-sectional area of between 0.1 mm 2 and 15 mm 2 , for example between 0.5 mm 2 and 5 mm 2 .
  • the or each passage has the same cross-sectional area throughout its extent.
  • the or each passage may comprise throated portions to assist the expulsion of air there from. The passages may thus have substantially the same cross-sectional area throughout their extent except at said throated portions.
  • the or each passage comprises an enclosed and open ended conduit.
  • the conduit is formed from a substantially gas impermeable and resiliently deformable material.
  • the or each passage comprises a tube.
  • the or each tube may comprise a cylindrical tube.
  • the sole component comprises a plurality of tubes.
  • the sole component comprises an array of parallel passages which preferably comprise tubes.
  • the sole component comprises a plurality of tubes lying side by side.

  • At least one tube has an outer diameter of between 1 mm and 5 mm.
  • each tube has a diameter of between 1 mm and 5 mm.
  • each tube has an outer diameter of around 3 mm.
  • the or each tube has a wall thickness of between 0.25 mm and 1.6 mm.

  • Adjacent tubes may be directly bonded to one another.
  • adjacent tubes may be joined by a bridging wall.
  • the tubes may be mounted to a backing sheet.
  • the tubes may be spaced apart to provide a gap into which the tube walls can deform when the tubes are compressed in use.
  • the tubes may be mounted to a backing sheet in said spaced relationship.
  • adjacent tubes are joined by a bridging wall which suitably holds the tubes in spaced relationship when they are uncompressed.
  • a bridging wall connects adjacent tubes at the tubes equators.
  • the sole component may comprise a plurality of bridging walls which may connect adjacent tubes at their equators.
  • the sole component may comprise a backing sheet which comprises a single bridging wall connecting the tubes.
  • the bridging wall or walls and tubes are formed integrally. The bridging wall or walls and tubes may be formed by extrusion.

  • the covering comprises a cloth material.
  • the covering may comprise a leather material.
  • the sole component may comprise a first (upper) and second (lower) sheet spaced apart by a plurality of walls, said walls being arranged to define conduits between themselves and the first and second sheets.
  • the walls may be spaced apart to provide a gap into which the walls can deform when the sole component is compressed in use.
  • the walls and first and second sheets may be formed integrally, for example by extrusion.
