A secondary school in Brighton has asked students and parents for their views on allowing children to wear trainers, following disputes over uniform rules.
Pupils at Longhill High in Rottingdean currently have to wear smart black shoes.
The school council suggested relaxing the rules and headteacher Haydn Stride said it could end petty arguments over what is allowed.
"It's for pragmatic reasons, not because I'm a keen believer in fashion," he said. "But we have this situation currently, and I'm quite sure we're not alone, where we are trying to decide what the appropriate footwear is.
"What makes a shoe a trainer? Is it the straps, the soles, the laces? At the moment the rule is almost unenforceable because there are so many interpretations of a black shoe."
The school is currently asking for views on changing the rule from black shoes to black footwear from Easter. Mr Stride said that some rules around what was appropriate footwear would have to remain. hw.
