"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 Bjorn Gulden said on Tuesday.

Clothing manufacturers are among the businesses hit hardest by tariffs as they source labour from countries such as China and Vietnam, which have faced steep levies from the US.

Adidas did not comment on how much prices would rise, but said the trade war had "put a stop to" an upgrade in its financial outlook.

Mr Gulden said it was "currently impossible to quantify" cost increases resulting from tariffs, "or to conclude what impact this could have on the consumer demand for our products".

"Given the uncertainty around the negotiations between the US and the different exporting countries, we do not know what the final tariffs will be. Therefore, we cannot make any 'final' decisions on what to do," he added.

Vietnam has become the global centre of athletic shoe manufacturing and it is subject to some of the most punishing US tariffs. Nike, Puma and Adidas all have large factory outlets in South East Asia.

Trump has introduced tariffs in a bid to bring manufacturing back to US shores. However companies such as Adidas say the US lacks factories with the specialised equipment to make running shoes and workers with the knowledge to operate them.
