Kinda of a dumb title but oh well. It seems like I have to buy a couple of new pairs every six months or so. I wear the things 5 days a week. They get washed weekly (duh ) bur they don't seem any better than most "non-labelled" brands at staying for the lack of a better word - "non-frayed." What has your experience been with them? I usually wash them on a warm permanent press cycle and dry on "normal" heat. Michael.
