I bought a pack (3 pairs) of these. I came back to buy two more packs.
  One reason is that there are few products for people who wear Size 15 (sometimes 14) shoes. Another reason is that after washing (wash cold, delicate cycle that I always use) they did not shrink.
  The main reason is that with the rubber strip on the heel, they stay in place all day and don't bunch up. Now to get regular sock manufacturers on line with this idea.
  Bonus: They don't show above my Docksiders.
