These failed for two primary reasons: started tearing during a crash, and slipped during crash and slip during normal use. I really wanted to replace my old huge 661 Kyle Straits, and get a little bit more shin protection without have full leg armor...these seemed perfect. They do look great, and they pretty low profile for aggressive pads. However, after 2 crashes, the strap on the rear mesh already tore, which makes me wonder how long the wrap-around mesh will last on crashes. The other issue is that they need to be pulled up quite often...even after the crashes. I have pretty small shins, but big thighs...and they start sliding down. The straps are also already maxed out wrapping around my leg (I'm 5'7" and bought the small size) so any stretching of the straps will require some stitch work.
The feel is pretty good though...they aren't flush on the knee, so there's a bit of room in the kneecap area but you get used to it.
All that being said, they are being sent back for warranty since they already torn after a handfull of use. All I'm saying is my old cheap Kyle Straits don't have a tear in the material...after 5 years of dh abuse and crashes. And the Kyle Straits never ever slipped off. It's unfortunate they tore so easily and slip, because the design is spot on.
