I'll tell you for sure at the end of the season, but they look pretty undestructible. Great attention to details too..the footbed opens to reveal the plate, and closes back with a clip. the double padding under your heel is REALLY comfy. And the camming mechanism that closes the binding looks solid and well thought out. Most of the parts can be changed, so I'm sure you can fix whatever wears out with time.
Thanks for the answers legallyillegal and pawlo.
That's just what I wanted to hear. I'm not looking for a full on freestyle binding, but rather a more freeriding binding. Glad to hear about the construction being more metal as I'm a heavier guy who likes to put his stuff through quite a bit of abuse.
