- The short answer is yes! Carv is used by racers to analyse their technique on a run-by-run and turn-by-turn basis
- The metrics Carv provides allow for a detailed breakdown of many of the core aspects of racing technique that coaches focus on
- It may be necessary for racers with extremely tight boots to modify their liners or bootboard slightly to provide space for the insole, however this is only the case with certain full custom racing liners and plug boots
An insight into how Carv can be used for race training
Carv has been designed to cater for the needs of both everyday skiers and racing skiers. In fact, we started the project by working with some of the best skiers in the world - including UK #1, David Ryding - to understand the core elements of skiing technique. Over time we have build these elements into an experience to help all skiers improve technique.

Features for Racers
Racers typically focus on raw data from Carv, to help direct their training. Every time you start a new turn with Carv, the system collects and processes the data from the turn you've just completed to generate over 30 metrics. These metrics are used to drive both the real-time coaching and post-run analysis features in Carv.
Carv's training section is split into Skill Development, Challenges, and Monitors.
Each of the Monitors correspond to a metric that Carv will report - through headphones - every time you finish a turn. For instance, if you are working on improving your edge angle, you can use the Edge angle monitor to hear your edge angle each turn. Likewise, if you are worried your right turn is stronger than you left turn, you can use the pressure monitor to hear you pressure each turn, and compare you left and right turns in real-time, as you ski down the course.
Post-run analysis: Pressure
After your run, you can get a summary for where you are putting pressure - on average - over your turns using pressure analysis screen.
Typically racers look to have early pressure in the turn. By checking at the end of each run, you can see this improve using this screen:
This screen will also reveal asymmetries in the pressure applied to your left and right turns.
Another important metric for racers is the ratio between outside foot and inside foot (Reported in Carv as Outside:inside pressure). High inside pressure is an issue associated with leaning too early into the turn. Top level GS skiers will typically have 70-90% of their pressure on the outside ski.
Post-run analysis: Edging
After your run, you can get a summary for where you are edging your ski - on average - over your turns using Edging analysis screen.
Typically racers look to have early edge in the turn, their skis moving together (Edge similarity) , higher edge angle (Max edge angle) and hold their ski longer in the turn (Max edge duration).
Fitting Carv to racing boots
Racing skiers with particularly tight boots may need to modify their boots or bootboard to best fit Carv. This is a similar process to fitting a boot warmer.
The cable runs on the inside of the boot on the outside of the foot and some racing skiers remove a channel. You can also create a cut-out in the arch to match the shape of the small electronics housing in the Carv insert to get more accurate pressure data.
If you are getting your liners filled with foam, we recommend you do fit Carv before the foam filling process. If you have any questions please consult your boot fitter who will be familiar with the equivalent processes when fitting bootwarmers to racing boots.
