So if I knew absolutely nothing about the whole tech insert failure, I would be like "whoa, these boots are the best I've had". But even with the whole insert failure thing, I can't get myself to subtract even a star.
I love these boots. If the internet didn't exist, there would be NO concerns about this boots durability and function coming from my mouth.
For me, great fit, even better performance, and a good compromise for me. I patrol, so I really like having the walk mode, and it's nice for touring. The BD walk mode on the factor had a bit more range of motion, but not enough that I was concerned.
