Depends on what you mean by “press” really
Moving your foot through a gas will displace the gas, and their 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.

I can imagine a scenario where you a gas is encased in a volume that you can reduce by stepping on it with your foot, thus pressurizing it.
