ABSTRACT:
A shoe is efficiently ventilated by forcing a low volume of primary air through a plurality of throttle orifices at high velocity downstream of a passage formed in a sole. A low pressure area is created within the passage. A high volume of stale secondary air from the shoe interior is accelerated into the low pressure area. The secondary air is entrained by the primary air and together form a combined jet-like air stream that is forcefully ejected from the shoe.
