The Jonas Brothers are about to take it off ... their feet.
Joe, Nick and Kevin are taking part in One Day Without Shoes tomorrow where they'll go shoeless to bring attention to the impact one pair of kicks can bring to a child's life.
TOMS Shoes is behind the cause, with other celebs like Kristen Bell, Hanson, Heather Graham and Brittany Snow joining in too.
For more info on the event -- including the locations of walks around the country -- check out the TOMS Shoes site.
