I have worn Wrightsocks for running, exercise, and casual for over 13 years since I discovered them. I bought a bunch of Running II model socks recently because my old ones are worn thread bare. The new ones are not of a quality for me anymore. When I wash them, the inside layer comes out and I have to push them back in and work to smooth the two layers out so they're not bunched. Even worse, where the inside and outside are sewn together at the toe, they are comin apart and I have holes after only 2 washings. This is the case on EVERY sock of all of the pairs I bought. Very disappointing!
