Frank Ocean's Coachella performance didn't put a bad taste in Rolly Romero's mouth ... 'cause the boxer will be showing love for the singer during his fight against Ismael Barroso on Saturday!!
TMZ Sports is told ... the lightweight fighter is a huge Ocean fan, so he hit up his go-to guy, Aztek Kustoms, to create boxing shoes featuring the Simpsons-inspired cover art of his favorite song -- "Pyramids."
The finished product is dope ... you can see the Nike Machomai 2 shoes are covered in orange paint with "Channel" stitched with rhinestones on the back -- paying homage to Ocean's Channel Orange album.
