SRD:Boots of Dancing

Boots of Dancing: These boots initially appear and function as one of the other kinds of magic boots. But when the wearer is in (or fleeing from) melee combat, boots of dancing impede movement, making him behave as if irresistible dance had been cast upon him. Only a remove curse spell enables the wearer to be rid of the boots once their true nature is revealed.
