The adidas Stan Smiths just got a little less ubiquitous out in the U.K., where one school has banned students from wearing them. Thornleigh Salesian College, a secondary school, is telling students seen with the shoes that they've got to wear something else, the Bolton News reports.

Apparently students have been telling their families about officials at the school letting them know the adidas sneakers are not acceptable–despite some of the students having worn the shoes all year.

According to the Bolton News, parents are claiming they never received any official communication about the shoes being against the school's uniform code.

Thornleigh Salesian College is threatening to keep kids wearing offending footwear inside during break times as punishment. The school is also offering to buy new shoes for students who've ran afoul of the rule.

It sounds like the school required students to wear "black leather lace-ups" and not trainers, although the Stan Smiths should be acceptable under this restriction.
