Bramble - Foot Insole Warmers (15 Pairs, 30 Total) - Full Foot Warming Insoles for Shoes and Boots - Air-Activated & Odour-Free - Up to 6 Hours of Heat

These are fantastic, I got them after being out for the day and my feet were that cold that I couldn't feel my toes, with these there's no more cold feet :)

Absolutely fantastic. They stayed warm all day. Happy warm feet, happy me.I bought a pack of 15 pairs. 1 pair didn't heat up, but all other 14 worked correctly.Brilliant product, will definitely order again.

The heat is amazing - but they don’t stay flat and you can feel them in your shoes - so fab for a little walk out but not for long days hiking, or biking.

Game changer in the cold weather and they last so long they even go into my slippers when I’m home!!

These were purchased for my two daughters who work outdoors, they say they are great and keep their feet lovely and warm

Good price but I've had better makes

Great for keeping feet warm - last all day

I have bought two boxes of 30 pair made by Therratherm which are good too but then I came across these by Bramble which are half the price. So why not it makes sense for me and for as long as I need to if Amazon keep them available I'll keep buying them.
