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.

Soft and tough. Easy on the feet. Nice fit prevents sore spots and blisters.
