Costco merino wool socks and spray anti perspirant on your feet.
I've never used liners so can't comment there.
this is what I do, thin nylon liners also if in extreme conditions like mountain climbing. Wool & antiperspirant has served me well from places as varied as the Makenzie mountains of the Yukon to the plains and boreal forest of Saskatchewan and the Pyrenees of Spain. In bitter cold and extreme heat. Rain or shine. I have not found a better combination.
