I wear Meindl walking boots - mountan boots for real mountains and a lighter pair for winter walking. I would not ride in either of them. I wouldnt want to ride in Commando soles.
As for smooth soles. My very expensive best Italian boots have smooth soles.
Just because something is expensive doesn't mean it's perfect, it just means someone is prepared to spend a lot of money - often the label is the biggest part of the price.
Where you ride is also a factor. If you hack on muddy - does anyone in the south remember mud? - tracks and may have to dismount to deal with badly hung gates or other obstacles then you really don't want smooth soled boots because you'll be slipping around on foot as well as having unsafe footing to remount or carry on riding. For school work or dedicated rides they may be fine, though they seem pointless if you then go and combine them with grippy tread stirrups.
