        Great for walking all day at work as well
        Size: X-Large, Color: (001) Black / Black / White
        I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

        You have one pair of feet. Treat them kindly with a pair of UA socks
        Size: Large, Color: (100) White / White / Black
        Soft and tough. Easy on the feet. Nice fit prevents sore spots and blisters.

        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!
