These really are better socks. As warm as Smart-wool, but more breathable and comfortable. I’ve bought 3 pairs.

After Thorlo and Smart wool were stricken with loss of quality, Darn Tough remain sole survivor in the world of high performance socks.

These aren't your dollar store socks. These things are tough! And the warmest socks that I own. No problem walking in zero degree weather.

山岳部出身の友人から、推奨されました。編上げや、革靴、トレッキングシューズ、バイク用のブーツ、で使っています。今まで、冬季に使ってきたソックスで、一番です。損耗以外、穴が開く気がしません。また暖かい。強いて言えば、緊急で履く時はちょっと大変。夏用も買ってみようと思います。

I have a new pair of hiking boots that was giving me a slight hot spot on the heel and I felt a thicker sock would fix the problem. So, I first purchased Darn Tough's mid-weight full cushion boot socks. The mid-weight socks worked but were a little thinner than I expected. I then looked at these heavy-weight tactical boot socks from Darn Tough and was wondering if there would be much difference for the added cost.The tactical socks are much thicker than the mid-weight pair and was more of what I was expecting when I purchased the mid-weight socks. The tactical socks are warmer as well and might be too much thickness for a summer backpacking trip but will work well in cooler weather or when you are carrying a heavy pack in rough terrain. In summer with a lighter pack I think I would use the mid-weight socks instead.I recommend Darn Tough wool socks. I am sensitive to wool, but these merino wool socks do not irritate my skin even after a long days hike. You do not feel the toe seams and the socks stay in place so you don't develop hot spots on your feet from the socks bunching up on a hard backpacking day.

登山にはこのくらいのクッション性が足には優しいかな。足サイズ26.5にはやや緩めだった。許容範囲ですが。
