What Can Carv Measure?

All of us want to ski with more grace and control, but it can be difficult to know what and how to improve.

Until recently, the only methods of tracking our skiing improvements have been inaccurate or subjective. Most of us rely on the following:

  • our friends’ or instructor’s comments,
  • a video camera or smartphone (ahem... those videos of a tiny dot skiing towards you),
  • a stopwatch (mostly used by racers).

With Carv in your boots, you’ll unlock Olympic-level coaching tools, and get a huge range of objective feedback that will trigger breakthroughs in your skiing progression.

Don’t believe us?


What can Carv actually measure?

We’ve worked with a number of instructors from a range of ski federations to create metrics based upon 4 fundamental skiing skills:

  • Edging,

  • Balance,

  • Rotation,

  • Pressure.

These metrics are designed to identify common mistakes made by the majority of skiers on the mountain. Read on to see how Carv will help you to identify and correct them.

Edging

Smoother Edging (Beginner/ Intermediate)

While developing parallel skiing, many beginner and intermediate skiers struggle to achieve a smooth turn and use a lot of energy on the mountain. Sound familiar?

This common issue is caused by pushing the feet and skidding out the tail of the skis to create a turn. Your turns will be Z-shaped, which result in less control as the ski design is not being used effectively.


What Carv shows you:

Carv measures how smoothly you roll your skis into and out of each turn. This measurement will improve as you start to focus on leaning into and out of each turn. Carv’s training (carving training mode) will help you to develop this important skill.

Christian Aigner explains how you can make C-shaped turns and ski with more flow in this video on our YouTube channel:


Earlier Edging (Advanced)

For more advanced skiers, it can be difficult to topple early enough in the turn to fully engage and hold the sidecut of the ski - creating the grip and directional control that makes high-performance skiing look so good.

What Carv shows you:

New this season, Carv shows you exactly how early you are rolling your skis onto their edges each turn. Great edging is all about rolling the ski over so you can engage the sidecut as you build up that outside ski pressure. Carv will tell you how early you are rolling up to the maximum edge angle of your turns. Racers, in particular, will be aiming to score highly in this metric.

Balance

Athletic Stance (Beginner/ Intermediate)

The most common balance issue for beginner and intermediate skiers is leaning too far back. With little pressure on the front half of the skis, you will struggle to make the ski turn when and where you want.

What Carv shows you:

Carv uses 36 pressure sensors in each boot to identify your center of balance, 25 times a second. It will tell you if you’re centered over your skis, too far backwards or too far forwards. Leaning forwards will give you more control over your turns and help you to break into the high balance scores.


Dynamic Balance (Advanced)

At an advanced level, balance becomes a more dynamic problem. Your balance point should vary slightly as you move through a turn, in order to keep your ski working effectively and gripping into the snow.

While it’s important to have your weight forwards while you initiate a turn, more advanced skiers should focus on holding their edge through the back half of the ski at the end of the turn. This will maintain grip into the transition, allowing the skier to hold their carve and direct their momentum smoothly into the next turn so they are in the driving seat again.

What Carv shows you:

Carv measures your dynamic balance by looking at how your center of pressure changes as you progress through the turn. Data that has been unavailable to skiers until now. As you focus on this technique, you’ll see your Dynamic Balance score move into the Pro Zone of 80-100.

Improve your balance with Carv

The Carv app has many features designed to help you improve your balance and fine-tune your skiing. Carv's interactive drills will take your skiing to the next level with turn-by-turn audio feedback, to help you get the most from your time on the slope.

  1. Develop your balance with Balance Training, and move through 20 levels of assessment.
  2. Use the Fore:aft ratio monitor to pinpoint your weight distribution.
  3. Tear it up in Free ski mode for audio feedback at the end of your runs.

Rotation

Skier struggles to keep skis parallel

Rotational Control (Beginner/ Intermediate)

Do you struggle to maintain rotational control of your skis and keep them parallel throughout the turn? When not parallel, the skis will move apart or converge into a snowplough, inhibiting your centred balance and reducing your ability to control the skis.

What Carv shows you:

With the Parallel Index metric, Carv shows you exactly how parallel your skis are throughout each run, so you can track your improvements. Improve your parallel index by transferring pressure to the outside ski more smoothly at the beginning of the turn. Your skis will turn more in parallel, and you’ll see your score approach the Target Zone of 60.


Pressure

Skier struggles to put pressure on outside ski

Outside Ski Pressure (Intermediate)

One of the foundations of skiing is learning to trust your outside ski. A common issue for many intermediate skiers is using the inside ski as a ‘crutch’, so as to not fall over when leaning into the turn. Learning to trust your outside ski unlocks huge potential for exciting carving skiing, and will help you to build control on icy terrain.

What Carv shows you:

Carv’s Outside Ski Pressure metric measures the distribution of pressure across both feet, so you can clearly identify exactly how much pressure is on the outside ski. This skill is very difficult to judge as you learn it, and until now skiers have had to develop numerous drills to help you learn this feeling. Carv will tell you the exact pressure ratio you’re getting, whenever you open your app.

A score of 100 represents all of your pressure on the outside ski, however, most skiers will be aiming to have between 60% and 85% of their pressure on the outside ski.


Turn Symmetry (Advanced)

Many advanced skiers have a dominant side when they ski, even if they are not aware of it themselves. This means that they achieve higher sustained edge angles in one turning direction, and struggle to ski with flow and control.

What Carv shows you:

Carv’s Turn Comparison: Pressure metric shows you which side is stronger, and by exactly how much, allowing you to track your symmetry as you improve. Try keeping pressure through the outside ski as soon as you begin each turn, to emphasise the pressure on the outside ski on your weaker side. Doing this successfully will push you towards the central Pro Zone, of between 45 and 55.
