I have a full season on my SMX Plus boots. They are really comfortable and I feel comfortable they are safe... two major boxes checked. There are a few small annoyances... they squeak and the toe slider has popped off a few times in transport. They also have one major issue, and I'm looking to replace mine because of it. The external hinge gets caught on parts of the bike at times, which can really mess up corner entry, shifting, etc. I removed the heal guards from my rearsets on one of my race bikes which has made it 75% better, but still have an issue once in a while. As the end of year sales come out, I'll be replacing these because of that one issue.
