After a performance in Dallas last Thursday, Franklin stepped on her shoe while packing.
Her spokeswoman said it caused the heel of her Jimmy Choo shoe to wrap around her toe.
She is now performing with a hospital boot on one foot and a designer shoe on the other. Her spokeswoman said the Queen of Soul has not missed any gigs despite her injury.
She was treated at an Indianapolis hospital Friday and continued on to a scheduled performance in Greenwich, Conn. The Grammy-winning songstress is expected to sing Tuesday night at the Wolf Trap in Vienna, Va.
She should be able to lose the boot in a few weeks.
