Feedback on how they fit / wear / comfort / walking around / etc?
Unfortunately the boots did not fit me well. I can barely get my feet into them when wearing normal athletic socks. Once in they are too short and not wide enough. With all the measuring and double measuring that we had done, I was hoping for a custom fit, but ended up with cramped feet. I attribute it to not wearing socks when measuring my feet - this was not in their instructions.
My wife says they are constructing a new set of larger and wider boots for me. We have not gotten a RMA for the first set yet. Hopefully the new boots will arrive shortly.
I find the rear zipper and rear belt fasteners to be somewhat cumbersome, though not terrible. They recommend using a shoe horn to get past the rear zipper. It literally took several minutes of struggling to get my heel in. I expect that would loosen over time, but I would much prefer a side zipper.
The Gasolina boots look nice. My teenage daughter said they look steampunk. The boots are very basic construction compared to modern boots. There is no insulation to provide extra comfort, protection, or warmth. If they fit, my new Gasolinas will likely wear in nicely and be fine for commuting, work, and local rides. Otherwise I may sell them for higher tech and more comfortable boots. My old Triumph Sympatex boots are better for sport touring riding and my Triumph AS4 are a lot better for walking, though they are falling apart again.
