You wouldn’t be able to press a gas with your foot though.

Depends on what you mean by "press" really

Moving your foot through a gas will displace the gas, and there will be a (albiet small) pressure difference around the foot as it moves through the gas. An increase on the side in direction of movement, a decrease on the opposite side of direction of movement, and some vortices on the sides.

Basically a very poorly designed wing.

Only under certain conditions.
