Definately smart wool socks.
I say darn tough due to their life time warranty and honestly any trekking pole will work. I use leki, my wife uses some cheap walmart one that she loves more than her black diamond and cnoc poles. Everything is personal preference. HYOH
IMO, SmartWool merino wool socks in the thickness appropriate to the temperatures you'll be hiking in, and Leki poles in the model that best suits your needs.
