I have used Altberg, Daytona (Non-Stop, Goretex) boots, and Sidi Black Rain boots over the years for road riding.
Altberg boots are heavier grade leather and give the impression of being unburstable. Downside is that have a Skywalk sole which would not look out of place on hiking boots. Sole is a good inch thick; great if your legs are short. I find them rather clumsy when on the bike; okay for winter but way too heavy & warm for summer use.
The Daytona boot are the ones which come out of the cupboard. Not quite as warm in winter but used for many journeys when the temperature (with windchill) was well below zero. Better feel for the gear and brakes pedals. 40,000 miles, two minor crashes and still going strong although sole is getting worn in places. I will buy another pair of Daytona's when these expire.
I have also used Sidi Black Rain boots for approx 12,000 before moving to Altberg and then Daytona. Sidi's are a man made upper (not leather), I found this prone to surface cracking which after 1 1/2 years led to water ingress. Relatively light weight construction; did not test the crash protection of these.
