What does "decent socks" mean? With the late Feb start date with low cut trail runners I'd 1) have shortie WP UL gaiters for the early rounds 2) be able to keep feet warm even though may be wet 3) know how to treat wet feet and prevent/address maceration and blister/sore feet/rash prone feet from LD hiking day after day after day in cold possibly wet conditions.
Snow, ice, cold, and wintry mixes will not likely be all that uncommon going forward through March. The Appalachian Mts can definitely experience late winter and early spring snow, ice storms, and wintery wet mixes.
