A few years ago I discovered that the Brooks Cascadia 7 trail runners were especially kind to my feet and also durable, but the Cascadia 8 was already on the shelves by then. I immediately went online and nabbed the last two pairs of Cascadia 7's in my size that I could track down anywhere. I have rationed my use of them and still have some wear left on my last pair. I'm not sorry that I acted fast.
