Abstract: The invention is with respect to fixing studs in the shoe soles. A sport shoe, as an example of the invention has pockets in its sole, into each of which the wider base plate at the end of a stud may be slipped and then locked in position tightly by a keeper washer with outward lock parts on its edge locking into grooves in the walls of the pocket like a bayonet-joint. For stopping the stud turning in its pocket it may have a hollow in its base locking onto an unround horn or the like on the floor of the pocket.
