wrote on my blog about a pair of socks knitted with the 4-ply knitting yarn from Rauma made of 100% wool from the Spelsau sheep. I have been using the socks on a daily basis since then. Indoors at home and at work, and outdoors in my winter shoes. I am rather amazed at the result. I did not think that the wool would last this long. This week the heel showed a small hole. The fabric was also a lot thinner at some places under the foot.
