Overall: Sub par sock even for the SALE PRICE of $7-$8/pair, but I'd never pay the $18/pair ($36 per two pack) normal price for these. Also, the merino content on these is low, so, while they are are stretchy/comfy, their durability and technical properties is questionable vis-a-vis other brands/socks with a higher merino content. I originally gave them 3 stars because the normal price of $18/pair is way too much for something like this, and I already notice some piling of wool after only a half day of use, but now all four pairs are terribly piled after only a few wears.
Now for details. These are 75% merino-15% nylon-10% lycra. What does that mean to me? It means where they lack in durability, odor resistance and ability to dry fast, they gain in stretchiness and perhaps comfort. What should that mean to you? It should mean that these are excellent socks to start replacing your everyday cottons or acrylics, and are also adequate socks for day hikes and other outdoor activities, HOWEVER, they should stay in your drawer or truck when you're really packing out in the woods or backcountry. I prefer a higher percentage of merino for these endeavors, and I think rightfully so.
The quality is satisfactory for the sale price of around $7-8/pair, but the normal price says $36 for a two pack, a price which I would be dissatisfied to pay once I saw them. With just a half day of walking around, I can already notice the wool/material on the heels piling up--a result of less than 100% merino wool use, and/or simply low quality wool (wool is quality priced on the market by strand length). I think the former is the case here, but I can't rule out the latter. So, for around $7-$8 a pair, they're a fabulous everyday sock, but at $18 a pair, I recommend looking into a sock such as Darn Tough (I simply cannot destroy my Darn Toughs, I love them).
