I've had mine about six months, and normally use them instead of my Sidi Dragons. I bought them big enough to fit two pair of wool socks, to allow for colder riding days, but they also fit fine with one pair of socks or barefoot if I tighten them a bit. I've used them for commuting, group rides, and a couple of 200K brevets. I may go back to my Sidis on the longer brevets, but might still wear the Keens. They are plenty comfortable.
