The HEAT company Insole Foot Warmers - EXTRA WARM - 8 Hours of Warmth - Instant Heat - Air Activated - Purely Natural - SMALL Size: 3-5 - 5 or 30 Pairs

So easy to use, popped straight into ski boot and made a days skiing much more comfortable. Although they do not get massively hot, they provide a nice and even warmth. The heat sole also provides nice extra padding for feet that has to be in the boot all day. Used a set each day, so very pleased with purchase.

These are amazing.....I wear them when watching my son play football, my feet get to stay nice and warm

I've only used one pair and they were pretty good I thought.

These are fab gone are the days of cold feet skiing. You can’t even feel them in your boot.
