Exclusive Details

The Packers D could have gold tracks across their asses Sunday, cause Marshawn Lynch is rockin' some SICK $1,000 all gold cleats for the NFC title game ... and TMZ Sports has the pics.

The cleats were hand made by shoe-customizing guru Solesbysir and feature 24K gold flake paint with a RIDICULOUS gold chrome plate at the bottom ... final value $1,100 bucks.

We're told Beast Mode had originally planned to rock the kicks on Super Sunday (confidence), but when he saw the finished product, he had to have them for the big game this Sunday.
