My wife and I love Merino wool socks! We have been wearing Wigwam brand for years and really they are the best but for the price these are nice! Soft, warm even when wet and really comfortable in any temp which is what merino wool is all about. These are not as heavy as Wigwams but not as thick either, so they fit an all my shoes and not just in my hunting boots. I would recommend them for a good sock for regular work boots or tennis shoes etc but not for extreme cold or in pack or hunting boots in those situations go with Wigwam. As for durability only had them six months but always hang dry them and so far so good. Some reviewers commented on percentage of wool content and I don't remember what the package said but they seem as comfy as others I have owned. I hope this helps!
