I just wear my gym socks golfing (low in white or black) when it's hot and when it cools down I'll wear my dress socks. If I'm playing in downright cold weather I'll switch up to some smartwools. I have yet to pull the trigger on some FJ socks, but I'm sure I will someday.
I only wear footjoy socks when I'm playing golf. I'll also wear them when working out or around with casual shoes.
