Only worn them about 35ish miles so far. So, ill give my 1 cent.

Didn't really have to break them in. Wore them for about 5 miles the first time with no problem. I did get them a half size larger(for long up/down hikes) so idk if that has anything to do with it.

I didn't get waterproof because, if you have ever ever done any long hiking, you know your feet will get wet anyway. Especially in the rain. However, they do stay relatively dry through wet grass and even minor puddles. Unless your on an angle then the seem slightly seeps.

The "superior traction" tag rings true. All 35 miles were wet and muddy. Had no problems at all.

Overall highly impressed so far.
