Because patriotism extends to the ankles.

Look, you're a fan of all things good and proper:

• Apple pie (made with organic apples).
  
  
• Hot dogs (made from organic turkey).
  
  
• Baseball (played with organic wooden bats).
  
  
• Super-villain pummeling with completely indestructible (and inorganic) shields bestowed by PROJECT: REBIRTH.
  
  

You adorn a patriotic, padded costume simulating Old Glory's color scheme, and sling said shield to enhance the effectiveness of said super-villain pummeling. 

Unfortunately, you're wearing steel-reinforced boots with nary a sock, and your augmented footsies are being torn to shreds while kicking landmines and tanks

Thankfully, our Captain America Suit-Up Crew Socks should help increase comfort and support while kicking the massive and dependable implements of conventional ground warfare.

Made from a soft cotton and stretchy polyester, these stylish Captain America socks simulate Cap's super-suit with red and white stripes, and additional uniform accents like stars and head-wings.

Yes, if you're looking for Captain America socks that A) deflect mortar fire, and B) match the suit, these government-approved shin-huggers deftly fulfill the needs presented by A and B.
