I wear SmartWools with a very thin polypro type liner if I'm traveling any distance. The polypro supposedly wicks moisture to the outer sock, keeping the foot dryer. Any "hotspots" or rubbing will be exacerbated with dampness.
Before starting out I also tighten my boot laces pretty tight, and may tighten somewhere along the way if I feel they've loosened. That keeps the foot from moving around in the boot, and helps to keep the socks from bunching anywhere.
Anyway, it works for me.
On short hikes I don't bother with liners.
