A German court is putting its foot down. Birkenstocks are not art. Birkenstocks are cool enough for influencers, Hollywood stars and even Barbie — but they do not qualify as art, Germany’s top court ruled Thursday.

The shoe manufacturer claimed its sandals “are copyright-protected works of applied art" that may not simply be imitated. Under German law, works of art enjoy stronger and longer-last intellectual property protections than ordinary consumer products.

Birkenstock sandals, which have evolved from a symbol of counterculture to a trendy fashion item, do not qualify as art and are therefore not protected by copyright, Germany's highest civil court ruled on Thursday.
