They are very soft, and feel great. Unfortunately, even when dried on low, they shrank to fit my wife's size 6 feet perfectly. She loves them, BTW.
I am size Eleven, and they would not even cover my heels after the second wash. (cold water, very low dry. Dryer temperatures may vary. and it is possible that my dryer is too hot. I recommend just hand washing and air drying, and size up, if you can.
