Body equilibrium

By subtly altering the density of their body and attaining perfect balance, even on unsubstantial or moving surfaces, the Jedi may stand or walk on surfaces that they would normally fall or press through, like snow, sand, or thin ice. Rumors exist of powerful Jedi moving across water with no more concern than a normal person would use to cross a room. Falling from great distances with this power "up" results in half damage, even if the Jedi does not land on her feet.
