Yes, I have a pair, about two and a half years old now and I tend to wear them on all my instruction and training events, as well as when just mooching about the wood.
They are very comfortable; warm when it's cold, not too hot when it's warm and I never have sweaty, sore feet anymore.
Always bone dry, except for the odd occasion I step in water that goes over the tops!
I tried them extensively during the first winter I had them; Helvellyn via Striding Edge, Sca Fell Pike as well as quite a few miles of lower walking.
Two drawbacks for me; They are quite heavy and the grip is terrible on wet rock.( except for the most coarse types of rock)
Seashore/rock pooling conditions? -don't!
I was quite disappointed by the poor grip afforded by the sole units, indeed, for these to be called a mountain boot, for me at least, they certainly do not "do what it says on the tin"
For all that, overall, I'm still pleased with mine, for mountain/hill work I use my Scarpa Manta's ( about 10yrs old now and well round the clock
) but for anything else the Lowa's are fine
cheers
