Smartwool socks are ideal for hiking. They keep your feet warm and dry due to their "smart" wool technology. Do NOT wear cotton socks while hiking, unless you want cold, uncomfortable feet.
The best Smartwool socks to get are ones that are designed with high density impact zones around the heel and ball of the foot (and toes). This helps reduce shock and abrasion, along with the Smartwool 4-Degree Fit System helps keep the sock in place. They have a bit of compression feeling around the heel and ball of the foot, which feels really nice for walking, hiking or backpacking. The last thing you want to get while out hiking are blisters, so it's very important that you wear the right socks.
These are all good options depending on the weather:

http://www.gotknowhow.com/amazon/B000NQKJ6Q If you haven't done a lot of hiking or are prone to getting blisters, you should absolutely get Bodyglide Original Anti-Chafe Balm (

Having a stick of Glide in your backpack can also be very handy, especially if you're out hiking and you start to feel the on set of blisters. Walking miles with blisters is no fun, so being able to put glide on your feet can be a lifesaver to reduce friction on your heels/socks/boots.
Lastly, it's always a good idea to put an extra pair of socks in your backpack while on day hikes, just in case your first pair of socks get wet during the day.
Hopefully, this info will help keep your feet toasty warm, and feeling good while out hiking!
