I wear boots socks all day every day for work and work outside in all weather. I just got 3 pairs to wear under tall boots and wore them all day on my feet in 80+ degree weather. They were warm but not too hot and the cushion is amazing. Not as tight as the "compression" socks from smart wool and... Read More

    Unfortunately....they led me to ordering multiple pairs of the wrong socks. It was based on % of wool. It may have nice wool in the foot area BUT truly none in the leg area. I have ordered smart wool socks before but am extremely disappointed in these specific model. In order to return the socks I would have to pay almost 7.00 dollars. I ordered 5 pairs of these thinking they would be the best for the cold Wisconsin winter. I had ordered 2 other different pairs. Rather than returning them it was just easier to order 3 more pairs of the good socks. They offer a great value....but Sierra Trading Post your return policy sucks as well as the price for shipping. You NEVER offer FREE shipping. So anyone wanting a better pair of great wool socks....you might want to order Item #7466A. These are a much better bargain and better for warmth. The alternative is Item #6997Y.
