The SO purchased these for me as a Christmas present. I really love the socks (which are very warm) and the grips on the bottom are appreciated as I am sure I would have slipped otherwise. I am just disappointed that the seam at the end of some of the socks are popping open. The socks fit really well otherwise and I intend on sewing a zig-zag stitch across the seam of the two pairs of socks that are opening as well as the remaining pairs just to cover for future reference.
