Win or lose ... Odell Beckham Jr. is hitting the field in style today -- the Rams star will be rocking a custom pair of $200K cleats featuring diamonds in them for the Super Bowl LVI pregame.
TMZ Sports has learned ... OBJ teamed up with Dominic Ciambrone, aka "The Shoe Surgeon" in L.A., and Jason of Beverly Hills to create "the most expensive cleat ever" for Beckham to wear on Super Sunday.
We spoke with Dominic -- who has over 1 million followers on his social media page -- and he told us Odell's 1-of-1 cleats feature yellow gold (symbolic of the Rams' colors) and 1,494 round brilliant white diamonds on the Nike swoosh sign.
