Review: A great source of heat for your feet (I use them when cycling early in the morning) - These are brilliant thermal pads, they keep my feet warm when cycling early in the morning (~6am). They're super eay to use, and very comfortable. The heat in the pad is oxygen activated, so I open the pack about 5mins before I'm due to leave the house, and waft them about to get some airflow over them, then I'll leave them for 2-3mins, before inserting into my shoes and leaving. Yes, they add a little thinkness to the inside of your footwear, so allow for that. I use them with size 43 shoes. Things to note: [1] They are oxygen activated, so if there's no airflow in your footwear you might have to re-activate them every now and again, yes by taking your foot out of the shoe. [2] These can get properly warm, if your foot moves a lot of air inside your footwear (like if you're jogging on the spot), so make sure to wear suitable socks. [3] One side of the insert is shiny, the other matt. Put the shiny side face down into your footwear. [4] In order to seal the active material into the insert there's an approx 10mm band around the edge of the insole where there's no activate/heating material. [5] They're single use. [6] You'll know when they're spent because the active material gets firm in the insole. [7] When they get wet...like raining on them wet because they deactivate.
Review: Happy - Excellent, does the job feet lovely and toasty

## Questions & Answers

**Q: What temperature do the insole foot warmers reach and how often can they be used?**
A: Our thermal insoles reach an average temperature of 39°C. If the warming time has not yet been used up: Pack insole foot warmers in a fresh-keeping bag and seal airtight.

**Q: I need size 39. The soles are offered in size 39-41. Isn't that too big for my shoes then?**
A: The insole foot warmers are designed for the smallest size indicated and also fit perfectly for the other shoe sizes indicated.

**Q: What is the shelf life of the insole foot warmers and how are they disposed of?**
A: The insole foot warmers can be stored for several years if unopened. You can read the exact expiry date on the package. Our insoles contain natural ingredients. This means that the foot warmers can be disposed of in the regular residual waste.

**Q: What is the optimal use for longer periods of sitting?**
A: Make sure that the soles are supplied with enough air. If you sit still for a long time, it is advisable to move your toes in between. Loosen very air-impermeable shoes a little if necessary.

**Q: What is the optimal application in ski boots?**
A: We recommend that you move your toes in between. This allows air to reach the pads. If the warming process really comes to a standstill, get out of your ski boots for a short time. The air will warm them up again after 10-15 minutes.
