I use these exclusively for when I'm hiking, cycling and walking ( exercising )
Size: X-Large, Color: Black
5.7.2019 Update: I have probably five packs of 3 of these socks. Can't explain it but recent pairs I've been using have lasted longer than previous two packs ( 6 socks )... So I'm going to get some more... They are my #1 go to sock for cycling, hiking, climbing, walking ( serious, training, speed, distance )... 10.30.19: I use these exclusively for when I'm hiking, cycling anqd walking ( exeqrcising )... They are light, comfortable, keep feet dry, cool & comfortable... They don't shift around on feet. They stay put once put on and running, climbing or cycling shoes are put on and laced up or ratched... I do a lot of hill climbing and also use on terrain where there's lots of long periods ( hours ) going up & hours going down... They don't appear to be very durable, get holes in toe or holes in heels, but 3 pack is relatively inexpensive so I continue to buy them. I do not use them for everyday casual wear because they would wear out very quickly compared to other similar sockets...

These socks are just OK. One arrived with a hole (easily sewn up, but kind of bummed about that). I prefer the Under Armour Resistor socks - they have support built into the socks that you actually can feel, and they were same price for 6 pairs!

Best sock I've ever had!

I have these same socks in white and gray, oh, and a couple of colors, and they are my favorite socks. They're the most comfortable, best-fitting socks I've ever ordered.
