Also FWIW...

it's not the feet part of the socks shrinking that gave me problems, it's the leg part. Cuts off the circulation in my calves, gives me leg cramps. Folding them down to my ankles sometimes helps, if they're not shrunk too much, but it doesn't always help, and it always looks super goofy. Not good for a $15 pair of socks.

And, I never understood why "hard water" was called that until I quit using the dryer in the summer time. You know the only reason why the dryer "softens" clothes when you're not using fabric softener, is because it beats them around for the length of the cycle and breaks up the mineral crystals or whatever. Shaking each item out very thoroughly after you take it off the line has the same effect.
