I have worn this brand of socks for years. Incredibly, my last pair just wore out after approximately 7 years of intermittent use. Love these socks. The fit is perfect and they are comfortable, even in the Birkenstocks.
I am trying the wool blend ragg sock even though I have an alergy to wool. They seem to be doing OK, but have only worn them a couple of times. For years I have worn your ltwt cotton ragg sock exsclusivly and was diapointed to find out that you no longer carried them. So I will try the wool. They seem to be of a weight that can be worn year round and if the wool does not bother me, they will be an adequate replacement.
I love these socks for both warmth and comfort. As others have noted, however, they do not run true to size and they do shrink. I wear an 8 1/2 mens shoe and that relates to a size M sock according to LL Bean. I have about 10 pairs and several of these have shrunk so much that they are just plain uncomfortable. The others I can stretch back into shape. Probably best to buy a size up.
