I served in the US Army for 21 years.  I thought when I retired, I wouldn't want to wear anything associated with the military.  But, over the years I have grown quite fond of OD green, again.  Ha!  I found these socks initially from a vendor at the Army Ten Miler, in black with green GI Joes.  I wanted another pair and started searching.  These run small so I had to return the Medium and repurchase the Large.  I wear a women's size 8.5 shoe.  The large fit well.  The socks are high quality.  Overpriced  but, I have my Army socks in 2 colors, now.
