Racing skiers with particularly tight boots may need to modify their boots or boot board 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 boot warmers to racing boots.
