Niners wideout Ray-Ray McCloud will channel Bow Wow's Calvin Cambridge for "Monday Night Football" -- TMZ Sports has learned he's copped a pair of custom "Like Mike" cleats for the big contest against the Rams!!
The 25-year-old receiver hit up Joe Castro to get the movie-themed spikes done ... and we're told after the Cali artist spent about 10 hours making them, they're now set to arrive just in time for kickoff.
The Nike Untouchable Speed 3 cleats painted in 49ers' gold and red came out pretty sweet -- with both shoes featuring depictions of Bow Wow from the movie.
