Not made to stand up to abuse.
I had these mounted on Kung Fuja's. Unfortunately, Marker decided to use plastic for the toe and heel part the latches underneath the tracks. That's where my heel separated. I'm not 100% when it happened, but I think it might have happened from a minor crash on a 45 foot jump.
NOTE: I did not buy these from BC.com. I have yet to take them into the shop to see if they will get warrantied.
