I bought these on March 14th. but today is the first time that I laundered them.  I followed the washing instructions and when I took them out of the dryer there was about a 5 inch square patch on the top left side that is all frayed.  It is not fixable.  I tried to shave it off but it didn't work.  It's too late to return them.  Now I have 2 more pair and when my husband wears them and they are ready for the laundry I'm going to take them to the dry cleaners and hope for the best.
