I have been using these boots for about 6 months in particularly difficult conditions (sharp rocks, snow - ice, mud, rivers, sand, thorns, gravel, etc.), walking several consecutive kilometers on such terrains. So far, the boots have proven to be very durable and have very good thermal and moisture insulation.
The disadvantages are that they are not very ergonomic and secondly, they are a bit heavy, meaning they are not suitable for long walks. However, as soon as they loosen up a bit, by adding good ergonomic insoles, things are much better.
I believe they are worth their money, but there is always room for improvement.
Note: Order one size smaller than your athletic shoes.
