  • At least a part of the sides of the holding recess is provided by the upper material. An example of this will be explained on more detail later.
  • the removable component is arranged for easy insertion in and removal thereof from the holding recess. This can be advantageous e.g. to be able to remove the removable component for drying and/or cleaning purposes. Also, this enables use of different removable components. For example, different sets of removable components can be used in running shoes depending on the type of exercise.
  • the structure can be such that there are no conventional elements such as a midsole between the removable component and the outsole. Lack of separate components such as a midsole can allow for an easy and quick alteration, even a substantial alteration, of properties and characteristics of a footwear. Also, a substantial part of the internal components can be removed for drying and/or cleaning by simply removing the removable component. Once the removable component is removed, all that is left is an empty“shell” formed by the sole unit and the upper, and possible leaner elements such as a strobel sock and/or a shank.
  • Cavities 1 1 are provided to receive air from co-operative resiliently deflecting diaphragm elements 6 of the outsole component 3 for generation of air flow within the removable component 10.
  • Air circulation channels 12 extend substantially laterally from the cavities 1 1 for distributing air forced into the cavities by the pumping action of the diaphragm elements 6.
  • Areas 14 adjacent to the cavities and air circulation channels are provided to seal the sole structure such that when the removable component is placed in the holding recess 7, air forced into the cavities and therefrom to the channels 12 of the removable component does not escape laterally from the channels 12 and the cavities 1 1 .
  • the air circulation channels 12 are provided on the underside of the removable component 10.
  • the removable component comprises perforations 13 extending from the air circulation channels 12 to the upper side of the removable component.
  • the perforations may be e.g. punched, drilled, moulded, laser cut to the removable component material.
  • Sealing areas 14 are also shown.
  • the sealing areas 14 provide sealing between the removable component and the outsole preventing air from escaping laterally from air circulation or distribution channels 12.
  • the air is guided along the channels 12 and through the openings or perforations 13 extending upwards from the channels 12 towards the interior of the footwear.
  • the removable component does not need to be fixedly attached to the outsole to retain the air in the channels. Instead, when the footwear is in use and the removable component 10 is placed in the holding recess 7, the weight of the user causes the sealing surface areas 14 be pressed against the surface of the outsole, thus sealing the channels. Materials of the removable component and the outsole components can be selected to optimise the sealing effect.
  • the material and/or structure of the removable component is such that the cavities 1 1 also enhance the pumping effect.
  • the cavities 1 1 of the removable component can be arranged to be of soft material such that the cavities compress as the user steps on the removable component, thus enhancing the pumping action forcing air into the channels 12.
  • Figures 3 and 7 show also how at least one of the air circulation channels 12 can comprise an expanded area 16 for enhanced air circulation in given areas.
  • Figure 5 shows a top view of the perforations 13 and the expanded area on the upper side of the removable component 10.
  • the expanded areas 16 can be provided on the underside of the removable component 10.
  • the expanded areas can comprise an appropriate pattern of perforations 13 for connecting the air circulation channels 12 with the upper side of the removable component.

  • a removable component can comprise a section providing characteristics of a footbed or sock.
  • a section providing characteristics of a footbed or sock can be integrated on top of a section providing characteristics that would have conventionally been provided by a midsole fixed to the outsole. An example of this is illustrated in Figure 6.
  • a footbed or sock part 20 covering at least a part of the midsole part of the removable component 10 can be provided with openings substantially matching the air circulation channels and openings extending from the air circulation channels.
  • the openings 13 may be produced to the footbed or sock, e.g. by punching, laser, drilling, water jet, or otherwise.
  • the openings can be produced at the same time with producing the openings of the midsole part.
  • Distribution of the perforations guiding the air into the interior of the footwear through the expanded areas is advantageous, e.g., because the air can flow with less resistance further from the cavities.
  • the air flow and even distribution thereof can be further assisted by upwards extending side grooves arranged on at least one side edge of the removable component.
  • side grooves arranged on at least one side edge of the removable component.
  • perforations connected to air circulation channels are arranged for distributing air only within the mid and front sections of the article of footwear while the heel section is free of such perforations. This can be provided to increase the amount of air forced into the front portion of the interior by the pods distributed on the entire bottom area of the outsole. Also, this leaves the heel section visible from outside free of any holes. In addition for aesthetic reasons, this allows better use of the heel section for, e.g., branding.
  • the outsole component may be side and/or comer stitched to upper material of an article of footwear.
  • a sole structure may also comprise at least one further component between the removable component and the outsole component.
  • the at least one further component can be arranged such that it does not hinder airflow from the diaphragm elements to the removable component.

  • a special machine can be used to make a strobel stitch to attach the strobel material to the upper.
  • the upper material 4 can be sewn to the bottom material creating a“strobel sock” construction. The material may have at least some flexibility.
  • the upper and strobel material can be strobel stitched together. After the upper has been lasted, the upper and strobel material can be cemented to the outsole component 3.
  • the strobel material such as the sock 30 can be perforated at locations 31 matching the diaphragm elements 6 and the cavities 1 1.
  • other types of stitching can also be used for the joining.
  • Figure 10A shows a cross-sectional view where a removable component 10 is in place in a receiving recess whereas in Figure 10B the removable component is removed from the outsole.
  • Figure 10B further illustrates an embodiment where stitching 33 extends through strobel material 30 and the outsole component 3.
  • Figure 10C is a cross-sectioned view of an example where the sides of the receiving recess 7 are provided solely by the upper material 4.
  • a structure for an article of footwear may also comprise other internal components, for example an internal shank and/or a heel element. Examples of possible internal components are shown in Figures 11 , 12 and 13. More particularly, a structure may comprise a shank 50 and/or a heel element 40. A function of the element 40 is to fill the volume in the heel section. The internal component are configured so that they do not hinder airflow from the diaphragm elements 6 to the removable component 10.
  • a shank 50 can comprise openings 51 aligned with diaphragm elements 6 of an outsole component 3 underneath and cavities 11 of a removable component 10 above the shank to allow air to flow through the structure.

  • a removable component may not be thick enough at the front part thereof to accommodate air distribution channels.
  • the air distribution channels can be provided on the top surface of the holding recess of the outsole in such areas.
  • the heel element 40 can also be provided with appropriate openings 41 aligned with the diaphragm elements 6.
  • the sectioned view of Figure 13 shows the opening 41 to be conically shaped. This may be advantageous in enhancing the air flow towards the cavity 11.
  • the opening 41 can have large enough diameter to be slightly larger than the diaphragm element 6.
  • smoothly tapering shape can be provided through the heel element 40 and shank 50 towards the cavity 11.
  • Figures 12 and 13 also illustrate an example of side stitching 5 between the outsole component 3 and the upper 4.
  • Figure 14 is a flowchart for a method of circulating air in an article of footwear comprising an upper, an outsole and a removable component inserted into a holding recess. Air is forced at 100 towards cavities in the removable component by resiliently deflecting diaphragm elements at the bottom of the outsole. Air forced towards the removable component by the diaphragm elements is distributed at 102 within the removable component by air circulation channels extending substantially laterally from the cavities between the removable component and the holding recess.
  • Pressure is applied at 104 to sealing areas of the removable component to maintain engagement of the sealing areas with the surface of the holding recess to prevent escaping of air forced into the removable component from the air circulation channels.
