Have you been skiing and seen another skiier going down the slope as if they were running on skis, practically lunging down the mountain? They were Telemark skiing or free heel skiing, and it's focused around the Telemark turn, which allows skiers greater control over their movements.
This kind of skiing requires special bindings that stabilize your toes while allowing your heel to lift up. You also need special skis and ski boots so you can bend and flex your foot.
Telemarking differs greatly from downhill skiing since you're able to bend your knees and lift your heels - kind of like walking or jogging.
It's definitely worth checking out if you're wanting to try something new on the mountain, but aren't interested in boarding.
