its nearly impossible to find any product that lasts anymore

before you use the new abyss boots, I suggest you mix up a bit of epoxy and coat the threads that are exposed - that will stretch the time before they will begin to wear - you would eventually need to do that anyways, so prevention is better than repair   

I have done that on my boots after the threads started wearing - better to do before (I have two pair - bought the secon because I liked the first so well) - I don't think I have bought any boots of any kind in the last 15 years or so that don't start falling apart sooner than I'd expect, especially for glued on soles - epoxy fixes most of that

the OTB abyss are good boots -

I found a boot I liked around 95. Small light comfortable and quick drying with ankle protection. GoreTex and smartwool in spring and a just liner sock in summer work well with them. When that first pair blew out it was available as new and improved from a spunoff company. So I bought another pair, maybe even another at some point I forget. When they were discontinued there I bought the last two pair in my size on sale from I forget where. I've been taking two pair so I always have a dry pair for camp. I have 2-1/2 pair left. I'm gonna miss those once they blow out.

Point is, if you find something you really like that works for you, stock up. That place eats comfortable boots.
