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.

Kids?
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I didn’t realize these were kids socks, until after I got them, but the fit is amazing and they stay put, without coming off my heels. I wear an 8.5-9 in women’s shoes.
