Goldilocks of socks!

Great socks....good support - the goldilocks. Not too thick or too thin; stay up nicely. Love the colors!

Best socks
Size: Medium, Color: Pink Elixir Assorted
Everyone got socks in their stockings this year. But no one was complaining. They weren't thin like some socks. But not super thick either. Just right. I even bought a pair for myself. No regrets. Will definitely buy again.

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.
