The present invention is for an adjustable ladder wherein one leg (side) of the ladder has an adjustable insert at its lower end, wherein the adjustable insert inserts into the short hollow side of the ladder. 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. Only one bolt is required to secure the adjustable insert to the short side of the ladder, facilitating quick and easy adjustment.
