A ballroom blitz of bad luck? Last week, they tumbled to the floor. This time, they had a footwear malfunction. Kirstie Alley and Maksim Chmerkovskiy fought through another week of Dancing With the Stars Monday night when Alley's left shoe fell off during their waltz. As they did after last week's fall, they recovered well and got a respectable score – a 22 out of 30.
