He has already one foot in the grave.
Swim with one foot on the ground.
A lie doesn’t have a foot to stand on.
One foot isn’t enough to walk with.
The same shoe does not fit every foot.
When the hand is put in, the foot follows.
Youth does not mind where it sets its foot.
Better the foot slip than the tongue.
Darkness reigns at the foot of the lighthouse.
An inch of virtue; a foot of demon.
Stretch your foot to the length of your blanket.
