I hike all day every day for a living. I even bought the 25 dollar wool socks and the still rub. They also just are not very supportive. I was looking for a taller boot that was not incredibly heavy but these are just too thin. That is why I believe they are rubbing my heel. They creese right on top of my heel when hiking in steep terrain. Nice and soft soles and work good for hiking on flat trails for an hour.
