4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ.
Love the socks but not the attention to detail the sock company did on matching left/right marked socks.

Hold up to tough wear - definitely recommend
Size: X-Large, Color: (001) Black / Black / Castlerock
These are my teens favorite socks. We've ordered multiple sets. Given that he tends to wear then as slippers I am really impressed with how they hold up. The extra large size is great for bigger feet. They wash well and I didn't notice any shrinkage, fading or pilling. This set is going to college with him.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.
