The shoes actually say OCLV on the sole. Optimum Compaction, Low Void.
I bought them barely used. So a little money for shoes that will out last me. I am cool with that. Not real sure I want to go grinding on my shoes.
Oddly, since that is a Trek term, could Nike shoes have been made by Trek??? The mystery deepens.
Bum Bum Bummmmm!
