I've had Altrider which cut my boot, D&S which was ok but I didn't like the look, and now the Touratech. I like the Touratech, they'll all keep you from catching your leg.
Unless your wearing Spurs your foot does not come in contact at all with it.
I removed mine and cleaned it up, I did notice the boot is not fitted tight to the engine or shaft Seems like dirt or water could get in at some point. so I zipped tied it on both ends..
