Darn Tough Merino Wool Boot Socks have a good reputation, especially among people who are into hiking and trekking. They're made from 66% Merino wool, 32% Nylon, and 2% Lycra Spandex, which, according to the manufacturer, helps keep your feet dry and comfy by wicking moisture away.

One cool thing about these socks is they come with a lifetime guarantee, so if they ever wear out, they'll replace them. Just a heads up, though—our research suggests you might have to pay for shipping during that process.

Now, about sizing—this can be a bit tricky. Most people find these socks comfortable even during long and tough activities because they help manage temperature and moisture, which is great for avoiding blisters.

While they might cost more upfront than some cheaper options, their build quality and performance usually make them worth it for those who need reliable socks in tough outdoor conditions.
