Not bad I was expecting them to fall apart long time ago but they are still good, almost no wear on them and nothing is ripped , the inside still good I've thrown them in the wash a few times and they do not shrink also they have a lining or a coating that gets rid of that gym shoe smell , i dont know what it is but is great , I love this shoes , I've increased my miles from one very slow mile about 3 months ago to 13.1 miles last sunday , no injuries no knee pain , my calves are huge now !!
