I can wear my crossfire's all day. I find them very comfortable even after 10 hour days. I also thought my Tech 3's were pretty darn comfortable too, but after I broke my ankle dropping my KLR on myself in my worn out Tech3's I upped the protection level with the Sidi TA's. Not sure if anything can really survive the weight of a KLR flopping on top of you but they are definitely a step up from the Tech 3's. I thought the Crossfire's were out of my budget, but then, those titanium screws the hospital sold me were pretty expensive too.
