I only managed a few rides in them prior to the ice moving in, but was amazed how comfortable they were from the second I put them on in the store. They are comfortable to walk around in from what I've experienced, but I've not gone on a 2 mile long walk in them or anything (though they feel like they could do it).
These boots are replacing two pairs of boots for me. A pair of old Alpinestar 8 motocross boots that hurt my feet after about 4 or 5 hours of riding. Also replacing a pair of slip-on leather street boots that never really felt like they would protect me much. The Adventures are far more flexible and compact (because they are bootyless) than my Alpinestar 8 motoboots, but they are less flexible than my slip-on leather street boots. The Adventures still allow me to shift fine, though with a bit more effort in the ankle than the slip-on boots. One can also lift up with your whole leg rather than flexing your ankle. That is what I needed to do with the Alpinestar because they were so stiff, so I'll be breaking that habit and shifting more with my ankle flex since the Adventures actually flex a bit.
As mentioned, mine have not yet developed the proverbial SIDI squeak. They will and that is fine with me. Besides my long weekend offroad and on road rides, I'll wear them into work. That squeak will be quite loud and everyone will hear me when I arrive and when I leave, but I've always switched to office shoes during the day anyway so I won't have people throwing books, pencils or computer monitors at me because of the annoying squeak all day long. Ha.
