Owning a few liner socks allows you to adapt your footwear for various conditions and uses. They are a great choice for summer or climbing shoes with a tight fit. Rotating fresh liner socks on a long hike or military yomp can greatly reduce blisters and improve morale. Level 1 means you can wear these as-is or with another pair (or two) of socks.

Made in Finland!

Our sock provider, Sukkamestarit, has joined the NATIVA system, which allows tracing the merino wool back to individual sheep farms. The packages feature a QR code for tracing the source of the Merino wool.
