Adidas has warned that new US tariffs will lead to higher prices for its popular trainers such as the Samba and Gazelle, as the German sportswear group said trade turmoil had “put a stop to” an outlook upgrade.

“Since we currently cannot produce almost any of our products in the US, these higher tariffs will eventually cause higher costs for all our products for the US market,” chief executive Bj?rn Gulden said in a statement on Tuesday. He added that it was still too early to quantify the expected price increases.

Sports shoemakers like Adidas are among the companies hit hardest by the Trump administration’s tariffs owing to their heavy reliance on countries such as China and Vietnam for manufacturing. The US lacks factories with the specialised equipment to make running shoes and workers who can operate them.
