Um no, I personally don't run them, 2 of my.ridimg buddies do. They were having issues with pin holes in the boots so they would send them back for replacenment. Then when they came out with that new style boot when they came.back they almost resemble the can am factory boots. Very stiff, they still flex, but are a very hard compound. They haven't had pin hole issues anymore, but the issue now is that the boot is so stiff it keeps popping off the axle joints. So don't go around trying to stir crap up throwing out assumptions.
