Eddie Hearn isn't blaming Devin Haney's footwear choice for his loss to Ryan Garcia ... but he does seem to regret the move just a little bit -- telling TMZ Sports it was "maybe" not a good idea for "The Dream" to rock Fear of God boots for the fight.
Many boxing fans took notice of Haney's Ugg boot-esque kicks for last Saturday's bout ... speculating whether he had enough support to compete against Garcia.
Hearn shuts down all that talk ... saying Haney was well-equipped in the ring.
