Abstract
A ventilation apparatus for an article of footwear has a hollow air pump chamber, one or more one-way air valves positioned through the top wall of the air pump chamber, and an air intake channel with a one-way valve coupled through an opening into the air pump chamber. Action of stepping down on the air pump chamber deforms the walls and increases pressure in the air pump chamber, and forces air out of the air pump chamber through the one or more one-way air valves positioned through the top wall of the air pump chamber, and action of lifting weight off the air pump chamber causes the deformed walls to return toward original form, decreasing pressure in the air pump chamber and drawing air in through the air intake channel.
