Claim:
1. Footwear, comprising a) an upper arrangement and a sole, in which: b) the upper arrangement comprises b.1) an upper material comprising in a lower peripheral area at least one air permeable portion, b.2) an air-permeable layer arranged in a lower area of the upper arrangement on a sole side above the sole, wherein the air-permeable layer is water vapor permeable and has a three-dimensional structure that permits passage of air at least in the horizontal direction; and b.3) at least one water vapor permeable functional layer arranged on an inner side of the upper material and above the air-permeable layer; c) wherein the at least one air permeable portion enables the air permeable layer to communicate with outer surroundings such that air is exchanged between the outer surroundings and the air permeable layer, said air permeable portion further enables the water vapor permeable functional layer to communicate with the outer surroundings such that water vapor is transported from an inner side of the functional layer to the outer surroundings; d) wherein a water vapor permeable first protective layer is arranged between said at least one air permeable portion and said functional layer in at least an area of the at least one air permeable portion above the air-permeable layer, wherein the first protective layer is adapted for protecting the functional layer against particles penetrating through the air permeable portion; and e) wherein the at least one air permeable portion comprises at least one air passage opening in the upper material, said air passage opening comprising an air permeable second protective layer.
