How to Choose Telemark Ski Gear
Imagine yourself in higher terrain, making first tracks in powder-filled bowls or chutes, enjoying the exhilaration of the downhill ride. This is where freeheel gear changes from backcountry touring to telemark.

Sure, you can carve the occasional telemark turn on backcountry touring skis. They're actually good for combining flatland striding with occasional downhill runs. But true telemark skis, which bear more resemblance to alpine skis, are designed almost exclusively for downhill travel. If you want to spend more of your time carving turns than touring, then "tele" skis are the choice for you.

Skis
Length
The right length depends on several factors: Your weight, skiing ability and the model of ski you're considering. If you want to spend the majority of your time on the steeps, a slightly longer ski will provide more of an edge and thus more control. If you like to ski fast and hard, a longer ski will be more stable. A shorter ski will be easier to maneuver in variable terrain and will be easier to turn at slower speeds. If you choose a ski with a large sidecut you'll want to go with a slightly shorter length, as well. Look for manufacturers' suggested sizing or ask a sales associate for more information.

Width
The width of telemark skis should match the width of your boots, plus be appropriate for the kind of snow that you usually ski. Most are quite wide for handling backcountry snow and supporting the added weight of a pack, but there is variation among models to consider.

•Wider skis make telemark turning easy in soft snow. They also allow your bindings to clear the snow when you put the skis on edge on hard-packed, groomed slopes. Be sure to wear stiff (usually plastic) boots that have enough power to keep wide skis on edge.
•Softer, leather boots are not as effective at controlling wide skis, so if you plan to ski in leather boots, opt for a narrower ski that is easier to power into a turn. (Most leather boots start out stiff, but soften up and lose their rigidity for steering.)
•It's easier for your rear ski to hold an edge on hard snow if your skis are a bit narrower.

Sidecut
Sidecut is the difference, measured in centimeters, between the ski's tip, waist and tail. Since they're used for carving turns more than striding, tele skis have significant sidecuts. Their waists are anywhere from 12 to 20mm narrower than their tips and tails. The broad tips allow the skis to plow through powder or mixed backcountry snow without catching, while the pronounced curves allow them to carve turns more easily than straighter skis.

Choosing between the different sidecuts is a matter of what you want the ski to excel at. If you want to spend more time on packed snow or groomed runs, a deeper sidecut will keep your edges against the snow and allow better carving.

Camber
Telemark skis all have alpine camber, or relatively little arch from tip to tail. Alpine camber distributes your weight evenly over the entire base of the ski, allowing for a smooth, continuous ski edge when turning. These skis don't have a raised wax pocket or kick zone like touring skis, so they are a bit slower for striding.

Flex
Telemark skis are typically lighter than alpine skis and have a softer flex, meaning they require less pressure to flex them into an arc. This flex or stiffness can be "measured" in the store either by holding the ski vertically and pushing on it, or by pressing down on it. Flex is how much the ski moves and then rebounds or snaps back in place.

•Softer, more flexible skis help you navigate the deep, soft snow found out of bounds and in the backcountry.
•For groomed ski areas and/or packed snow, you should opt for stiffer-flexed skis for better carving control. You also need stiffer skis if you get into telemark racing.
•Choose a medium-flexed ski if you want to ski on a variety of snow conditions and varied terrain.
Metal Edges
A standard feature of telemark skis, metal edges bite into hard, icy or steep snow and provide control. They make descents much easier.
