The definition of durability is subjective. it’s a full synthetic boot, nothing is more durable then full leather.
I don’t think a rand starting to peel is a major durability issue, I’ve had to re-glue rands on zamb, Hanwag, Lowa etc. majority of issues I’ve seen is rand peeling
I think I will get about 3 years out of mine and I average about 300’ish miles a year on them specifically. I rotate between them and hanwag Yukon/ancash.
I had a blow out 3/4 days before an Aug sheep hunt last year. I bought them because I figured minimal to no break in. I did 10 miles first day in then and felt great. Then left for 10 day 13k sheep hunt. Zero issues. And zero issue rest of the year hunting elk, deer and bear.
My only complaint is I wish they were a 4 flex
