Abstract
Systems and devices are described for creating a more effective mechanical ventilation system for footwear. For example, a mechanical ventilation system can include an air reservoir that is almost as large as the entire shoe under the footwear's foot bed. In some examples, the air reservoir can be connected to an area that includes a foot of a user in the footwear. The air reservoir can be compressed using a movable part that circulates air in the footwear with every step. The movable part can be relatively small, extending into the air reservoir, and able to compress and inflate the air reservoir. Movement of the movable part can cause a large effective compressible area of the air reservoir to release fresh air near the toes of a foot to flush stale air out of the footwear.
