10,000 pairs of fake Nike trainers worth £250,000 have bee seized by Essex Trading Standards.
The counterfeit footwear was discovered in a trailer from Latvia at Harwich by the UK Border Force, who then asked Essex Trading Standards to examine them.
They were then seized by trading standards and will be destroyed.
If the footwear had been genuine, the loss to Nike could have been as high as £800,000.
Cllr Roger Walters, Essex County Council Lead for Trading Standards, said: "I am pleased that another consignment of counterfeit goods has been intercepted before reaching the public.
"Counterfeit goods are never worth the money for consumers.
"There are no guarantees with counterfeit products and there are no assurances that their production meets the required safety guidelines."
