I have had these for about a year and a half now.
I probably have about 11,000 miles on them and 1 or 2 track days. They currently are the only boots I own. The only thing that I don’t like is they are not water proof. I got them for less from Riders Discount. The only damage I see is on the left boot sole, pic below.
Some scarring on the inside and 1 of the red inserts is gone. Sole seems to be solid still and the rest of the boots look the same as the day I received them. I’m happy so far with the boots. I’m guessing they’ll last at least another year or 2, maybe longer. When I bought these Mike was still working at Riders and suggested another option was the Sidi fusion. It was a little more expensive and me being cheap, I chose these.
