Very comfy
Size: X-Large, Color: White
I'm a size US Mens 14 with huge calves. Finding comfortable crew socks can be somewhat difficult.
These are extremely comfortable, very stretchy and soft. Very worth the price.

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...
