Ultimately, not worth the extra cost
I wanted to love these socks, as they were very comfortable and fit perfectly from day 1. However, I did the two week+ challenge, and did not experience any improved circulation, foot comfort, or warmth. They're great as a good quality hiking or winter sock, along the lines of darn tough or smart wool. They are significantly more expensive though, with no added benefit. Glad I can return them, but am out the initial shipping cost (guess I rented them for a couple weeks)
