Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

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.
