These are very, very soft and comfortable.  Some folks wrote that it wears at the heals, and they were absolutely right.  It wore a large hole at the front ball of my foot even more quickly than the heals.  I was surprised because they have extra padding there.  They started by leaving material on my feet after each wear.  They only lasted 6-8 months after about 15-20 wears, which is the worst from any socks I've ever owned.  I was so disappointed because Adidas is normally a well known brand.  Will definitely not buy them again.
