Members of Iran's soccer team have resorted to asking other players to loan them footwear or individually purchasing cleats, ESPN reported.
ESPN reported Monday that the decision follows the USA withdrawing last month from the Iran nuclear deal.
The decision was accompanied by new economic sanctions.More news: American toddlers consume way too much added sugar, says study
Sports apparel giant Nike on Monday said it will not supply Iran's national soccer team with boots for use in this month's World Cup in Russian Federation due to concerns about economic sanctions against the country.
"Sanctions applicable to Nike have been in place for many years and are enforceable by law", Nike added.

"It has been a source of inspiration for us", Mr Queiroz told British broadcaster Sky Sports.
"We are only managers and footballers, and should not get involved in such matters".
In a widely-shared video, an Iranian man who described himself as a dentist threw a pair of Nike shoes in a bin, saying the company's decision was "an insult to my people and all football lovers". While the sanctions are meant to put pressure on the country's economic system, it appears the move has had the unexpected repercussion of leaving Iran's players scrambling for shoes only days before they play the biggest games of their year. "There was a time our sportsmen were symbols of national pride. This is the impact of politics on trade rather than political interference in sport", said another.
