The present invention is for an adjustable ladder wherein one leg (side) of the ladder has an adjustable section at its lower end. This enables the ladder to be placed against a vertical surface without tilting from left to right or right to left, even when it is standing on a surface that is uneven or slopes in a direction that is non-perpendicular to the vertical surface that the ladder is leaning on.
