Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

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.
