Merino wool socks..? Preferably not ugly..?

My buddy recently introduced me to merino wool socks – he swears by them to prevent foot odor. I grew up with awful itchy wool that we only busted out in the dead of winter, but apparently new sheep are silky smooth and make socks for every day use, even in the heat. They aren't cheap though, and most that I've seen are either a super outdoorsy pattern or kinda lame gray. Do any of you wear merino wool socks day to day? Any good-looking brands you'd recommend??
