Scoring technique, accurately

Accuracy is at the heart of our system. Carv compiles data from every turn you ski to measure specific elements of your skiing.

As you ski, the device captures what you’re doing with raw objective data. Carv then displays your data against benchmarks.

Ski:IQ:


Your technique, explained

Carv reports your Ski:IQ after each segment (when you stop). This score gives you one accurate assessment of your overall technique, and number to track as you improve.

  • Carv will transition your turn types from wedge to parallel to carving. You will develop consistent stability and balance through your turns that will get you tackling increasingly more challenging runs with ease.

  • Carv will take your fundamental technique to the next level. Form satisfying C-shaped carve turns with ease, so you can crush it on the entire mountain and carve down any terrain.

  • For experts, Carv will unlock completely refined technique by finessing your edge angles, progressive edge building, fore:aft balance and more. Carv can show you what truly effortless skiing feels like and get you closer to complete mastery.


Carv’s Ski:IQ assessment is based on thousands of labelled video sessions, refined with the top ski instructors from every major association - powered by data from over 350 million turns.

Skiing Fundamentals

Our metrics fall under the four categories developed by the Professional Ski Instructors of America so you can develop the best technique.

  • Carv measures how you move your centre of mass throughout the turn. It looks for you to move forward at the start of the turn, and then get back a centered position, over your bindings during the main phase of the turn.


    Great balance allows you to effectively manage the changing forces you experience throughout the whole turn to adjust for the terrain that you are skiing.

  • Skis turn on snow because of the contact between the snow and the ski’s edge. The most efficient turn comes from tilting the ski, allowing the shape of ski to provide the turning force.


    The more edge angle you achieve, the tighter your turn will be which will mean you experience more force in the turn (and more fun).

  • Skiing is all about how your skis turn on snow. Rotational skills mean your skis are turning together, giving you flow and style on the mountain.

  • Carv is able to measure how much pressure you create on each ski, when you apply this pressure and how smoothly you do so. New this year, it can now measure the g-force you withstand from your turns.


    Applying the right pressure allows you to reach high g-forces, and create stylish, high edge angle turns.

12 Powerful Metrics

Carv breaks down your skiing into 12 objective, accurate metrics that make up perfect technique. Carv will help you improve each metric so you can really ski with style.

Terrain adjustment

The best skiers are the ones who move effortlessly and absorb any terrain. Carv constantly assesses the terrain you’re skiing on, rewarding you for keeping your technique together as the pitch and terrain get harder.

Track your day

  • Carv tracks every run automatically, but not every run is the same. Our segmentation feature cuts the run into meaningful sections to analyze.

  • For those who love to full send, Carv is great for capturing your speed and seeing how far across the mountain you’ve journeyed.

  • Carv can also track your day with accuracy. As the device knows how much pressure is on your feet, It even knows when you’re on the lifts to calculate vert precisely.


    The map data combines GPS with movement tracking for clearer mapping. So it won’t confuse you for being on a lift for taking the exciting route down underneath the lift.

Answers to common questions about the Carv data

  • How accurate is it at scoring different abilities?

    Carv has been trained on over 350 million ski turns, compared against a database of ranked and labelled video sessions of every skill level of skier (paired with the Carv data from those sessions). This means that Carv can accurately detect your skiing no matter what level you are.


    Each season the team develop and releases metrics that will help you understand your technique and improve, even if you’re at the top of your game.

  • How does it know how I’m skiing from just my feet?

    Your feet are the single point of contact between your body and the ski. Even though Carv cannot see your upper body, it can see the effect your body is creating. For example, Carv can assess how the center of pressure moves in your feet at the start of the turn, and might give you a tip about moving yoru body forwards as you initiate the turn.


    It will also analyze the timing of your movements and it will compare left vs right ski, which means Carv can give you advice on how your weight and balance is distributed, alongside measuring things like how early you get on edge for carving turns.

  • How does the data get processed in real time?

    Carv sensors record your skiing 20 times a second using motion and pressure sensors. These data are sent to your phone via bluetooth where they are analyzed in real time as you ski. The first step Carv takes is to determine the turn window (when your turn took place) and the second step is to construct your metric scores in real time.


    Carv then reacts as you ski and will then send audio coaching to your headphones (via cable or bluetooth), so you can make a change in your skiing during your run. When you stop your run or get on a chairlift, Carv creates a segment and your overall Ski:IQ is calculated.

Want to know more?

1. Carv Captures your skiing data

The Carv device captures precise pressure and motion data as you ski. It is then sent to your phone using bluetooth.

Your ski data is then compared against professional benchmarks (Level 3/4 ski instructors) to assess your technique.

2. Get feedback on your technique

This data is then translated into 13 powerful metrics that fit into 4 key categories:

  • Balance (forward/back lean)
  • Edging (edge angle, similarity and more)
  • Rotation (rotary smoothness and similarity)
  • Pressure (outside/inside ski, smoothness and more).

So you'll be able to analyse your technique and find out where you need to focus next.

3. Improve in days not months

You'll get personalised tips, real-time coaching and drills, developed with the best skiers and instructors like 2x Olympic Gold Medalist Ted Ligety.

The fast feedback loop from objective data, to coaching and back means you'll ski more efficiently and for longer, have better control and confidence, take on more challenging terrain and push your limits.

Yes, Carv is the same thickness as a boot warmer at 3mm. It will fit in almost all ski boots including stock boots, custom moulded boots and boots with custom insoles. We offer a boot-fit guarantee so you can find the perfect match with Carv.

Yes. Carv goes under the liner - on top of the boot board. This means that heel lifts, custom insoles (e.g. Surefoot), and boot warmers are not affected and are compatible with Carv. You can use them both at the same time.

99% of our customers are happy with their Carv fit - even pros like 2x Gold Olympic Champion, Ted Ligety, ski with Carv without boot mods. Because it fits under the liner, there is padding to accommodate the 3mm volume. If you do have a pinch, a boot fitter can rectify issues. If not, you are protected by our boot fit guarantee.

iPhone

Carv is compatible with any iPhone that has a minimum of iOS 15 installed, though we recommend using the most up-to-date version of iOS

Android

Carv requires a minimum of Android 8.0 to run, and your phone must support Bluetooth 4.2.

Carv is designed to improve your form on all terrain.

Carv will automatically detect the difficulty and snow type that your skiing on - taking into account steepness and terrain variability (bumps, crud, powder). Carv will adapt your score based on the terrain so you're always rewarded for keeping your form when things get dicey.

Carv's coaching is focussed on developing an efficient, controlled and stylish technique. It will push you to make more stable, rounded and exciting turns. While Carv is not designed to coach you in off piste (yet), the improvements it will make in your fundamental technique will certainly iron out issues so when you do get the perfect pow conditions of the season - you are focussed on your line not your technique.

  • Carv works with regular headphones, Airpods and any other bluetooth headphones. See our recommendations here.
  • Almost all helmets work with in-ear headphones, so you don't need to make adjustments to your current helmet
  • If you do not want to ski with headphones, you can still improve with text-based tips, scores and drills.
