I am presenting a new magical item below in Pathfinder RPG format, but I am sure the more mechanics savvy readers could adapt it to the system of their choice. The wonderous item allows characters to make additional 5′ foot steps (or shifts, in 4th edition parlance) that becomes effective for maneuvering into a more effective combat position (think flank & charge).
Scoundrel’s Boots of Maneuver
Aura faint transmutation; CL 5th
Slot feet; Price 7,000; Weight 1 lb.
When taking a 5′ step, the wearer of these multi-buckle leather boots, as a free action, may elect to move an additional 5′. These boots may be used to increase the distance of a 5′ step 3/day but may not be activated more than once per round.
Requirements Craft Wondrous Item, haste; Cost 3,500 gp
