Benefits of technology

[0013] According to the present invention there is provided 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, wherein the sole component comprises at least one compressible passage extending between a first portion of the sole component and a second po

Problems solved by technology

Regardless of their specific sole construction, 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.
When 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 bacte

Embodiment Construction

[0095] As illustrated by FIGS. 1 to 4 a first embodiment of a sole component comprises an insole 1 arranged to fit within an article of footwear 2.

[0096] The insole 1 comprises a plurality of silicone rubber tubes 10 having passageways 11 therethrough, arranged side by side and bonded together. Most of the tubes 10 are arranged to extend between a heel portion 20 and a toe portion 30 via an arch portion 40. Each of the passageways 11 of these has a first opening 21 at the peripheral edge 22 of the heel portion 20 and a second opening 31 at the peripheral edge 32 of the toe portion 30. Owing to the shape of the insole some tubes 10 and thus passageways 11 do not extend from the heel portion 20 to the toe portion 30. Such tubes can though still perform an active role as will be discussed hereinafter.

[0097] In the illustrated example, the insole 10 is sized such that it will fit a UK mens size 11 shoe. It is provided with markings 15, 16, 17 indicating where it should be cut to provi...

Abstract

The invention relates to a footwear sole component and to an article of footwear 2 comprising such a sole component. A sole component is suitably an insole 1 with toe and heel portions 30, 20 connected by an arch portion 40, the sole component being arranged to form part of a sole of a closed article of footwear 2 having a foot chamber 90. The sole component includes at least one compressible passage 11 arranged, in use, to have an opening into a first region of the foot chamber 90 and an opening into a second region of the foot chamber 90 such that air can be caused to travel from passage 11 into a second region of the foot chamber 90, by a pumping effect caused by compression of the passage 11 along at least a part of its extent during a stage of a wearers walking cycle.

Description

FIELD OF THE INVENTION [0001] 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. BACKGROUND OF THE INVENTION [0002] There exist various types of 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. [0003] 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 there...
