Couple of mates have the TCXs and really rate them. Good solid boots for all seasons and reasons - KTM Adv to BM tourer.
Me, I'm an Altberg convert: I've got a pair of their classic roadster boots that I've worn almost daily commuting for the last 10 years plus some serious outings to Morocco, numerous Euro trips, rattling around Salisbury Plain etc etc. They are such old friends that I had them resoled last year. Sadly the uppers are now starting to crack up, so I reckon maybe 12 months use left. I'll be buying another pair, even though they are maybe a little short compared to the TCXs and leave some shin exposed.
Re the ATV boots further up the thread, they look the part, but a mate bought a pair for the last Morocco trip we did, as a substitute for his full-on MX boots. He found the soles too soft and flexible for serious off-road use. However, as you say, comfortable to walk around in: designed for farmers etc who spend a fair proportion of their time off the quad, so perhaps a fair compromise overlander boot.
