    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.

    LOVE THEM!!
    Size: Small, Color: (001) Black / Black / Castlerock
    LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

    So will not write down your foot
    Size: Medium, Color: (001) Black / Black / Castlerock
    I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

    Comfy and Stay Put
    Size: Medium, Color: (002) Black / Black / Halo Gray
    These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
