After wearing them for quite a few years I say yes. I had a couple pair come apart just above the welt when I worked for a cryogenic liquid company. I figured that it was from the occasional touches of -300 degree liquid. At my present job I started wearing a pair I had that were nearly new, but sat in the box for about six years. They came apart at the welt near the heel. The guy at the Red Wing store said they came apart because they "were just old". He also said they could not be repaired. Well, the wife had them repaired for relatively cheap, about 40 bucks. I always oiled them with Red Wing oil. Still come apart. No more. Bought some work boots from Sears, made in China of course. Comfortable, light weight and lasted a long time (2 years). For the money, one pair of Red Wings = four pair of my present boots. Just wondering if anyone agrees?
