Review on 🧦 281Z Hiking Insulated Liner Socks by Jason Graham

These aren't really boot linings. These are just loose socks made from Polartec fleece. They do not maintain the shape of the boot or shoe. They are no different than slipping a second pair of socks over the first pair. You can't leave them in a pair of boots, so just slip your feet (with socks) into the liner when you're ready.
