Boots of Gravity

These leather boots allow the wearer to choose the direction of gravity's pull on him and his equipment. The character can move normally on any solid surface by imagining "down" as being whatever is below the boots. A character can make this decision once per round, as a free action. If the wearer of the boots drops an item, it falls toward the ground as normal.
The wearer of the boots can carry another living being, and so long as the wearer does not let go of the second character, that character's gravity is the same as the wearer's. However, as soon as the wearer releases the character, normal gravity takes over.
Technically, a character wearing boots of gravity can fly by choosing a solid surface and letting himself fall through the air toward it. A character "flying" in this fashion moves at 60 feet per round. He can turn once per round thereafter by choosing a new "down" and falling in that direction. A falling character loses all "downward" momentum when he redefines his gravity.
