Kids at a school in New Zealand are swapping their sensible shoes for a strange fashion trend - slippers!
The boys have switched to the more comfy footwear, and so many of them are breaking the rules that they can't really be told off.
One teacher told a newspaper in New Zealand: "We can't end up sending 20 kids home each day."
It's thought the weird trend started when American rapper Snoop Dogg was spotted wearing slippers out and about.
He also slipped on a pair for a magazine interview, prompting kids to make an unexpected change to their uniforms.
Some of the boys have said their shoes are broken or that they left them in their parents' car when explaining their odd shoe choice to teachers.
