I like the ankle length, they don’t slip.
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I love these socks, they are thick enough to not be scratchy, thin enough to be cool and breathable.

Fit great
Size: Large, Color: (100) White / White / Halo Gray
Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.

Always a win

Fit well and stay up

They're a little thin, so good mainly for warmer months. But they fit very well and I've not experienced any slippage
