These boots have had 2 years of use (2 Scottish winter seasons and 3 alpine trips).I have replaced the complete soles (rubber outsole and plastic midsole) this summer. The soles are in great condition.
There is some delamination around the rubber uppers on the outside, this is mainly cosmetic.
These boots have another good couple years of use in them!
I am happy to send additional photos and answer any questions.
