comfortable and soft, very good to use with mountain boots

"Best socks, ever!"

Yes, I would recommend this product.

I bought so many different kinds of socks trying to find the best socks for work, and none come close to the comfort and quality of the Darn Tough Mountaineering extra cushion socks. They stay up all day in my work boots. I really like the way the tightly woven Merino wool feels, and they are tough as nails. These are my favorite boot socks, my feet stay warm in the winter and are not too hot in the summer. Try a pair and you will not regret it!
