Wool socks are usually enough for my feet, though sometimes I slip off my shoes and sit on my feet in my chair. I especially like "smart wool" socks, but right now I'm wearing socks made from camelid wool! (Alpaca, in this case, but it's
almost llama.
)
I've found that "wristies" (sort of fingerless gloves made from polyester fleece) help a lot, and they don't get in my way while I'm typing. I have low blood pressure, so I also tend to get cold, especially in the extremities.
I have not found a way to keep my nose warm that I can tolerate, however. Partially it's probably due to the allergies making my nose irritated and tender all the time, partially because I really don't like to have anything touching my face. I wear glasses, and that's the limit.
