If you're not skating, you have no reason to be pinrolling your pants.
Unless you don't want indigo rubbing off on your shoes 
Why would that even be a concern? 
I'm guessing you've never owned a pair of raw denim jeans. There's still a blue gradient around the tops of my white GL IIIs...
I've owned them in the past.  In the 80s.  Having moved to pre-washed jeans and being one that heavily favors lighter hues of blue, I have no need of raw denim any longer.  Not very comfortable, shrink to fit, and I wouldn't want to wear them until I'd washed them a few hundred times to get them faded to an appropriate color.
It's one of those things where, having gone through it decades earlier, I might get a pair for nostalgia eventually but I can't say it's a high priority.  I'd rather a nice faded pair of RRL during some super discount sale.
