Jaire Alexander will be honoring Queen Elizabeth during the Green Bay Packers game in London on Sunday ... with these new custom cleats featuring Her Majesty.
TMZ Sports has learned the Packers organization reached out to celeb artist Joe Castro last month -- in order to have custom spikes made for their 25-year-old cornerback for their big game against the Giants.
"They wanted something to commemorate the Queen while they play in England," Castro tells us.
And, Castro delivered!
