I'm extremely sorry and don't want to be a downer, but there not durable at all. I have them and I've skiied like 8 days and it looks like I've had them for a year.
that's a bummer to hear. i won a pair of these and got them detuned specifically so I could hit rails. Haven't gone into the park yet this season though.
Yeah I heard some people say they weren't that durable, but I hit rails all season and didn't get any edge cracks, mine were perfect, guess I just got lucky.
