Fully Waterproof Design

built for the snow

Tough yet sensitive

We’ve packed 36 pressure sensors and a motion sensor into each insert and built it to withstand hard days of skiing.

The best part is, because Carv fits under the liner of your boot, you can use it in custom moulded ski boots, stock boots or rentals. It even works with your custom insoles.

Batteries that will outlast your legs

We’ve optimised the battery chemistry to handle the cold, giving you over 3 days of skiing per charge. That’s more than anyone’s legs can handle.

Built to fall

Carv’s battery pack sits on the strap of your boot with a specially designed clip and a robust case to keep it secure, no matter how radical your turns (or how often you fall).

The world’s best ski tracker

We’ve developed Carv’s metrics with intermediates, instructors and racers to make sure it picks up the smallest differences in technique of every skier.


Are you leaning too far back?

Balance is the foundation of great skiing. Carv shows you if you are centered over your skis and gives you balance exercises to help you improve.


How well are you engaging your edges?

Rolling your skis smoothly into and out of each turn gives a skier great control (and that sweet carving feeling). Learn how to edge your skis together and create higher edge angles.


Are you turning your skis smoothly, in parallel?

Carv measures your parallel movement and your left/right symmetry. Ironing out those inconsistencies is the key to efficiency and style.


Are you really on the outside ski?

Balancing against the outside ski is the foundation of great skiing. Find out how much pressure you've got on each ski and where in the turn you are applying it.

Recommendation Engine

Carv analyses how you ski by comparing your turns with data from some of the best instructors in the world (instructor-examiners PSIA, CSIA, BASI, NZSIA, APSI).

Find out what is holding back your technique and get the right advice to fix it.


Want to know more?

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.

Most of us end up skiing at the same level for years, especially if we are already an advanced skier.

We hit a plateau because it is hard to know where the next breakthrough will come from.

We designed Carv to take the guesswork out of great skiing:

  • Push your carving to the next level with detailed analysis
  • Improve your consistency and efficiency
  • Create higher pressure and edge angle.

If you can beat the top level drills and master the Carv ski challenges you'll be doing better than most instructors.

Carv is not optimised for off-piste skiing. However, powder skiing often highlights small issues in technique which can become the difference between beautiful tracks and twisted knee joints.

Carv helps you to find and iron out these issues on the piste. Work on your edge similarity, turn symmetry and pressure control so you can focus on your line not your technique in the powder.

  • 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.
