From Tardis Wiki, the free Doctor Who reference
Laser shoes were gadgets created by MI6 for operatives to use in the field. They were given to Graham O'Brien and Ryan Sinclair by "C" before they investigated VOR CEO Daniel Barton with the Thirteenth Doctor. Graham wore them whilst attending Barton's birthday party, though would use them to fend off the Kasaavin. He later used them to threaten Barton's men into surrendering. (TV: Spyfall)
