A motorcycle boot is described with a positive air circulating system which distributes air over the wearer's foot in a continuously replenished flow. Air enters the boot through air scoops on the upper sides, travels down an intake duct at the rear, is distributed along the sole through a network of open channels, and flows against the underside of the wearer's foot through perforations in the inner sole. An exhaust path is provided through vent ports above the sole, exhaust ducts which run up the rear of the boot on either side of the intake duct, and vent openings which exhaust the air to the outside. Openings may be provided in the scoops immediately above the vent openings to produce a venturi action that stimulates the flow of air through the boot.
