Merino socks are, by far, the best out there.
Primus and Snow Peak have been the most reliable and longest lasting fuels I've tested. The best thing? The AT towns know what you want and need, they will have plenty of IsoButane already in stock for you.
Drinking purified water is a necessity when it comes to hiking the AT. However, you don't need heavy and expensive pumps. Chemical drops are the most lightweight and simple option you'll find. I only use bleach these days because it's so simple and easy to use: 3 drops per liter, shake, and let sit for half hour. It is always good to have a sieve or some sort of strainer to prevent any chunks getting into your water. So have one handy when filling water.
Buy your footwear from a company with a lenient replacement policy. You will go through more than one pair of shoes/boots; it will more likely be three to five46. For this reason, getting your footwear from a company with a lenient replacement policy is huge. Salomon, Merrell and Keen have a good reputation in this regard. Be sure to mention that you're an Appalachian Trail thru-hiker on the phone.
