Talk to me about knees. Starting to give me issues on long hikes coming downhill. Tele seems like it would beat on the knees.
By comparison skiing alpine groomers I consider almost no knee impact. Bumped up or fresh snow and heavy wet stuff yea that takes a toll. Same theory on tele impact? More or less than alpine on same conditions?
Not surprisingly, there's no consensus. One might think it's worse, but again, you have the option to stay up or get low. Some people say they ski less aggressively, so their knees feel better. Some say they ski more aggressively, and their knees feel better. Some people say their knees hurt no matter what.
Oddly enough I know far more Alpine to Tele converts who have knee injuries or bad knees than the other way around. Some people claim it's easier on your joints because the boots have more degrees of freedom and are softer.
People say all sorts of shit...
It's certainly more tiring. But it's only more tiring when you actually Telemark turn, which is not a necessity.
I'm also trying to think of one single person I know that's actually tried Tele that disliked it. It's definitely harder and you have to rethink some things, but the modern gear is so close to Alpine gear it's not that different. Put on some leather boots and real freeheel (no cable) bindings and point 'em down a hill. Then you'll know challenging skiing and perfecting technique and balance.
