A structure (2) and a removable component (10) for an article of footwear are disclosed. A structure comprises an outsole component (3) comprising resiliently deflecting diaphragm elements (6) for generation of pumping action for forcing air towards the removable component placed in a holding recess (7). The removable component comprises cavities (11) facing the outsole component and arranged to receive air from the resiliently deflecting diaphragm elements, air circulation channels (12) extending substantially laterally from the cavities for distributing air from the cavities to the air circulation channels, and sealing areas adjacent to the cavities and air circulation channels. The sealing areas are arranged to prevent air from escaping the cavities and air circulation channels when the removable component is inserted in the holding recess. Air circulation channels (12) may be provided with expanded areas (16). The expanded areas may have varying shapes and number of perforations.

A closable drainage system for a sole of a shoe, the closable drainage system including a drain configured to communicate between sole top and bottom surfaces of the sole, the drain having opposing drain upper and lower faces; at least one drainage aperture element disposed within the drain, the drainage aperture element defining a drainage channel which communicates between the drain upper and lower faces; and a movable member overlaying the drain upper face, the movable member movable over the drain upper face to provide open and closed conditions of the drainage channel; whereby in the open condition, the movable member disposes to allow passage through the drainage channel and correspondingly, between the sole top and bottom surfaces; and whereby in the closed condition, the movable member disposes to preclude passage through the drainage channel and correspondingly, between the sole top and bottom surfaces.

A forced-air footwear is presented and comprises a foot supporting portion including a sole with cavities therein covered with a foot-contacting layer, and a channel communicating between the cavities and the interior of the footwear to allow air flow between the cavities and the interior of the footwear; a foot covering portion, the foot covering portion including a valve allowing air passage therethrough in a single direction, the cavities including a compressed configuration, when supporting a weight of a wearer, and an expanded configuration when not supporting the weight of a wearer, the passage between the compressed configuration and the expanded configuration forcing an air movement of the air contained in the cavities, the valve blocking the air movement in one direction, wherein the compression of the cavities and the blocking action of the air by the valve is forcing air through the footwear.

A shoe and a method for controlling the shoe are provided. The shoe includes a vamp and a sole. The vamp is coupled to the sole, and the vamp and the sole form cooperatively a shoe chamber receiving a foot of a wearer. The shoe further includes a controller and, a communication unit, which are arranged on the vamp or the sole, and a first pressure sensor arranged on the vamp. The controller is electrically connected with the communication unit and the pressure sensor. The first pressure sensor is operated to detect a pressure on a preset area of the vamp, and output corresponding pressure data to the controller. The shoe is communicated with a user terminal device by the communication unit. The user terminal device is operated to display the pressure on the preset area of the vamp according to the pressure data.

A ventilation sole for footwear, the sole including: a communicating vent-hole through which the inside and outside of footwear communicate with each other to allow air to flow; and a valve selectively opening and closing the communicating vent-hole, wherein the valve includes: a housing module configured to have opposite ends being open such that a channel is provided therein to communicate with the communicating vent-hole; an open-close module configured with a first closing surface and a first through-hole; and a rotation module configured with a second closing surface and a second through-hole, and rotating to move a position of the second through-hole. Accordingly, a wearer can easily open and close the valve by rotating the rotation module according to the intention of the wearer, whereby air inside and outside the footwear can be circulated selectively and optimal foot conditions can be improved.
