Hands: I just bought a pair of Extremities Tuff Bags mitts. These things will get a lot of use in cold, wet weather next fall. Made from GoreTex Paclite, fully seam taped (so no seam sealing necessary), reinforced palm for durability, and still pretty light. Waterproof and windproof. I believe these will be replacing my eVent mitts for good.
For colder, not so wet weather, I also bought a pair of Extremities Velo gloves. For a couple of years I've really liked my Manzella silkweight Windstopper gloves with some type of light merino liner, but the Manzella gloves wear out quickly in the 'thumb crotch' area when using trekking poles (as pointed out in a BPL review). The Velo gloves are the same design/outer Windstopper fabric, only with a light lining (so no merino liner necessary) and with a reinforced 'thumb crotch' area. I believe these will be much more durable and can't wait to try them out next fall!
Feet: If it's not cold, I don't worry about it, I just get wet feet and carry extra socks. If it's cold, I'll either wear GoreTex socks, or a plastic bag, over my regular socks. I also wear MLD eVent gaiters.
