Great socks
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
Love these little socks. Soft and stay in place, no falling down in my shoe. I will definitely be buying more. Holding up well after multiple washings.

Great fit, no slip
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
These looked too small for my feet, but now I love wearing them as they are comfortable and stay on my feet! They look great and the colors are easy to match. Excellent value for the money in my humble opinion.

good, worth the value
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
Well it was delivered quick, and all my socks are mostly under armour, as they have developed holes in the heels now, so here i am getting a new set. they fit great, comfortable as usual. some folks may have some sort of issues, while some dont and i cannot complain. worth buying for sure. i recommend
