I purchase socks when i purchase shoes. I can usually get a better deal that way and I am getting all of my foot needs taken care of and know how the socks and shoes feel together. I thruhiked with 2 smartwools and 1 darn tough. wearing cheap nylon liners from wally world. all three pair lasted my entire hike. i replaced the liners often (300miles) for comfort. i never had any blisters or raw feet.
