An article of footwear (1) comprising:
- an upper (8) having a first ground facing surface (9);
- a primary sole part (10) having
- a first foot facing surface (11), and
- a second ground facing surface (12),
- the first foot facing surface comprising a plurality of openings (14), each opening defining a volume (14A) extending in a vertical direction from the first foot facing surface (11) towards the second ground facing surface (12) having a closed end;
- and
- a secondary sole part (20) having a second foot facing surface (22) and a third ground facing surface (23), wherein the secondary sole part (20) is arranged between the upper (8) and the primary sole part (10) and extends into the plurality of volumes (14A) in the first foot facing surface of the primary sole part.
The article of footwear (1) in accordance with any one of the preceding claims, wherein the primary sole part (10) defines a mould cavity of the secondary sole part (20), where the plurality of open volumes (14A) of the primary sole part (10) define the mould cavity of the secondary sole part (20).
The article of footwear (1) in accordance with any one of the preceding claims, wherein the secondary sole part (20) is direct injection moulded into the plurality of open volumes (14A).
The article of footwear (1) in accordance with any one of the preceding claims, wherein the secondary sole part (20) extends from the first ground facing surface (9) of the upper (8) to the first foot facing surface (11) of the primary sole part (10), and/or where the secondary sole part (20) defines a second foot facing surface (21) that is attached to the first ground facing surface (9) of the upper (8) and a third ground facing surface (22) that is attached to the first foot facing surface (11) of the primary sole part (10).
The article of footwear (1) in accordance with any one of the preceding claims, wherein the primary sole part comprises a peripheral surface (13) defining an attachment area adapted to accommodate a tertiary sole part (30), optionally where the quaternary sole part (30) has a radial inwards facing surface for attachment to the peripheral surface (13) of the primary sole part (10) and an outwards facing surface.
The article of footwear (1) in accordance with any one of the preceding claims, wherein the plurality of openings (14) extend from a heel area (5) of the primary sole part (10) to a forefoot area (4) of the primary sole part (10) in a plurality of parallel rows extending in a lateral direction of the primary sole part (10).
The article of footwear (1) in accordance with any one of the preceding claims, wherein the second ground facing surface (12) comprises a ground contacting surface.
A primary sole part (10) having
- a foot facing surface (11), and
- a ground facing surface (12),
- wherein the foot facing surface (11) comprises a plurality of openings (14) defining a plurality of open volumes (14A) having a closed end (14B) for receiving an injected material, wherein the open volume extends in a vertical direction from the foot facing surface (11) towards the ground facing surface (12);
- wherein the foot facing surface (11) is configured to be joined to an upper (8) by receiving the injected sole material extending between a ground facing surface (12) of the upper (1) and the foot facing surface (11) of the primary sole part (1).
