Rated 4 out of 5 by from Work well in cold weather I have very cold feed and these insoles are comfortable and fit my Hotronic batteries. I use them in my back country ski boots.

Rated 4 out of 5 by from Fits well Rather pricey but I needed a replacement since one of my existing wires had separated from the connector and there is no way to repair it. The replacement was easy to install and is a comfortable fit. Unfortunately I had to buy a pair even though I only needed the left boot warmer.

Are these compatible with the m4 battery packs?

Asked by: Slo
No, these insoles are only compatible with Hotronic S4 battery packs.

Do these insoles require a small hole to be cut in the back of a boot insert or can the cables be run inside a single thickness boot? I am wondering if these insoles would work for single thickness climbing boots and back country ski boots.

Asked by: Andy01
These are intended for alpine style ski boots with a liner. They require the wire be routed up between the shell and liner.
