Living in Florida I’ve really never needed a winter sock before. However, I’ve been hunting in Indiana since 14’ with the last year doing adding a late season hunt. I received these socks today and my first impression is they will increase my ability to stay in the stand with warm feet. They’re really soft and comfortable all the way up my calf and the size XL ensures a good fit with my Size 15 foot, which I find is difficult to find a good fitting quality sock. If for some reason the durability is not up to a five star review I will return and add comments.
