Generally, the best way to store wool clothing is by folding them after cleaning and storing them in a vacuum bag or an air-tight container for no more than a year. If your wool clothing is stored for more than a year, you need to take them out and allow air-drying for a bit before restoring. In particular, socks need to be washed following washing instructions and folded flatly after they dry, before storing them in vacuum-packed bags. You can add some cedar to the package to ward off bugs and other creatures.
