Carv will not be damaged by boot warmers or dryers, as it has a maximum continuous operating temperature of 70°C.
The Carv tracker is attached to the outside of the boot, and the insert is installed between the liner and the shell. Both of these take up the same position as many boot warmer battery packs and inserts respectively. We therefore support using Carv alongside internal boot warmers, but advise you to use your judgement when installing, as when combined they may cause a tighter fit in the boot and discomfort.
Here is an image demonstrating where Carv’s inserts and trackers sit in your ski boots:
We recommend installing the Carv insert on top of the heated insole, to ensure it provides the most accurate data possible.
