Yes, you can wear wool socks every day. There are a variety of wool sock designs to keep you comfortable no matter the weather or activity. The same wool socks can also be worn every day on backcountry trips. Most hikers swap socks out every 2 to 3 days, while others trek in one pair of wool socks for up to a month. Having a pair or two of wool socks on a trip is ideal so you can wear a clean pair while you wash the dirty ones.
