Steadfast boots
(feet)
These thick, heavy boots are reinforced with iron along the sole. When wearing steadfast boots, the wearer gains a +8 bonus to CMD against, or on any checks or saves made to avoid, being bull rushed, overrun, tripped, or otherwise knocked down or moved against his will.
Furthermore, as long as the wearer of these boots carries a two-handed weapon, he is treated as if he had readied that weapon against any creature that charges him (and thus it deals double damage if his attack is successful), even if the weapon can’t normally be set against a charge.
All the powers of the steadfast boots work only when standing on a solid surface (i.e., they do not function while the wearer is flying, swimming, etc.).
