I have only had these boots a few days so cannot comment on how these stand up to general wear and tear. However, I have been very impressed by how comfortable these boots were straight out of the box. It appears that there will be little to no 'wearing in' required. Also, the boots are very substantial but do not seem clunky or cumbersome, which is especially good when on rocky terrain.

The only thing that I did not expect was how high the boots come up on the leg. Having worn mid boots for the last 4 years, this is something I will have to used to but will likely prove beneficial.
