Ventilated footwear has in a sole thereof a pumping chamber formed in a heel portion of the sole and bounded by two parallel top and bottom walls and a peripheral wall which is resilient to bias the pumping chamber and has converging upper and lower wall portions extending from the top and bottom walls of the chamber. Air is supplied to the pumping chamber through an air inlet passage and is exhausted from the pumping chamber via an air outlet passage.
