Nyheim Hines is ready to be both Josh Allen AND Santa's helper this Saturday ... the Bills running back just copped some awesome cleats for Buffalo's Christmas Eve game -- that are elf-themed!
TMZ Sports has learned ... the tailback -- who was traded to the Bills in November -- wanted a Xmas design on his feet to celebrate the holiday during the pregame of Buffalo's tilt with Chicago. So, he hit up his main cleat artist Rodney Jackson for the hookup .
