These were donated to our charity shop with no information.  They are size 18 custom painted Nike Football cleats, not mass produced.  On the left shoe it reads SiZ  #MCMC.  

I understand that this design was initially made for DJ Fluker for the NFL's "My Cause My Cleats" initiative, and feature a special "I'M A FATHER FIRST" design. 

Please ask questions and I'll do my best to answer them.
