New Balance Suing Karl Lagerfeld Over Shoe Design -- Sneaky, Sneaky


New Balance is waging a sneaker war against one of the most iconic names in high fashion ... claiming Karl Lagerfeld ripped off its trademark sneaker for his new shoes.

According to a new lawsuit -- obtained by TMZ -- New Balance claims Lagerfeld is using a block capital letter "K" on an otherwise identical shoe design.  NB claims this creates confusion.

The sneaker company points out it's been using this design since the '70s, noting even fashion blogs have seen the similarity ... one with an article titled, "Wait did Karl Lagerfeld just knock off New Balance sneakers?"

New Balance wants to stop Karl in his tracks.
