Excellent quality and construction. 66% Merino Wool, 24% Nylon, 8% Polyester, 2% Spandex.
These socks are very comfortable with the extra padding on the sole. Being make of Wool, they are very warm on cold days, but being moisture wicking, they are not TOO warm on hotter days. My feet stayed dry during my rounds in 90 degree weather. The thick sole helps a lot when walking 18 holes. The thinner top section allows my feet to fit in the same size shoes as I normally wear.
I wear a size 10.5 shoe, and a size Large sock is supposed to fit size 9 to 12 shoes. I found these socks to be a bit small for my feet. One size larger might be the way to go.
While I did find these socks to be a little small, they did perform very well. They were very comfortable during my rounds walking 18 holes. Good moisture wicking on hot days, and warm on cold days. There is nothing better than WOOL for a really good pair of socks to keep your feet warm and dry. Excellent padding on the soles makes walking 18 holes a little easier on my feet.
