A couple of weeks into a thruhike I always experience the same phenomenom: My brandnew soft and cushy socks (I usually use Darn Tough or Wigwam) become stiffer and stiffer although I wash them in a washing machine with laundry detergent once a week while having a rest day.
Even back home where I can wash them with a long washing cylce and use fabric softener they stay stiff which unfortunately causes chafing on my feet.
Is there a way to revive stiff socks?
