Hi,
I'm very satisfied with my Viking Cerra.
I walked over 40 km until now in muddy and stony tracks and my feet were ok.
The sensations are new for me because I was not accustomed to so flexible boots and wide, just like running shoes. My old trekking shoes were more rigid and fasten my foot.
I like to feel my feet free to move inside the boots and free of any kind of compression...
For the moment, no trouble about the water proof properties...
Waiting for more rainy days, in order to test definitely this point.
Good purchase and really a good relationship price/quality. Vibram+Goretex.
