Following its recall of 690,000 children’s clogs last May, Payless ShoeSource will call back another 270,000 clogs for toddlers because of a choking hazard on the shoe. The clogs feature popular children’s characters like Dora the Explorer, Spongebob Squarepants and Hello Kitty. They were sold for $15-20 at Payless stores from January through last month.
