In reply to Misha:
Misha, its not your technique, its just a really poor design on all of the new lightweight boots resulting in a sole that is unable to take the rough & tumble of a few days out in the alpine environment.
Struggling to explain the difference, but have a look at the old school Evo's sole at the front, nothing like the lightweight, therefore its able to take the abuse for far much longer.
I'm speaking from experience here, cost me 75 Euros to resole a pair of tranga guides after what seemed like a few days out walking, certainly not tempted to purchase any more light weight boots with the same toe design in the future.
To add insult to injury, it was the same sole for the resole!
