Frequently asked questions

Are your insoles suitable for downhill skiing?

Unfortunately not: our insoles need to be compressed by around 2 to 3 mm, and alpine ski boots are generally adjusted so that the foot cannot move.

For ski touring and snowshoeing, however, our insoles are perfectly compatible.

Can I use these insoles barefoot or are socks recommended?

Our material is hypoallergenic, except for those allergic to TPU and/or copper.

Does everyone feel the thermal effects?

The thermal effects are not always felt, yet at the end of the day 90% of users say their feet were neither hot nor cold and that they remained in their comfort zone. The strong point of ClimFeet insoles is that they are invisible; they are neither heating nor air conditioning.

I can't feel the heat. Is this normal?

In our tests under winter conditions, around 10 % of participants didn't immediately feel the heat, even though the temperature had risen by over 3°C. This may be due to differences in blood circulation, which sometimes prevents the difference from being perceived. We recommend that you use the insoles for an hour to feel their thermal well-being.

If you are not satisfied, we offer a full refund. Return the insoles to us, even if cut, and they'll be recycled.

Do your insoles really produce heat or coolness, whatever the outside temperature?

Our CLIMFEET insoles do indeed provide warmth and coolness in all weathers, but they are most effective in very high or very low outdoor temperatures.

In fact, as in any thermodynamic machine, the compression caused by the impact of your feet on the ground irreversibly produces a little heat. So if the outside temperature is around 20 to 30°C, you may not feel a thing.

Why do you use copper?

Copper allows us to improve heat transfer and distribute it evenly throughout the insole.

Do your insoles cause you to lose a shoe size? Should I go up a size?

Our insoles are 6mm thick, so if you are used to wearing tight shoes, then yes, it would be better to buy shoes one size larger. You can also remove the original insole (socksole) if it is not glued.

Are your insoles comfortable?

Our CLIMFEET insoles have nearly 260 air-filled cells that act like air cushions that cushion every impact your feet make on the ground. They are therefore very comfortable and absorb shocks much more effectively and evenly than insoles with only a few cells.

How long do the insoles last?

The lifespan of our insoles depends on their use, but on average they can last up to 2 years.

What is the advantage of your insoles over other thermal products on the market?

Our insoles are the first reversible insoles capable of producing heat on one side and cold on the other, without batteries. Unlike existing products, which use resistors that can overheat or explode, our insoles are not only safer, they're also environmentally friendly. They are recyclable and generate no CO2 emissions during use.

As far as the cold part is concerned, no insole on the market offers this feature, although "ventilated" insoles do exist. However, these are not effective in hot weather, as the air entering the shoe will be as hot as the air outside.

Is it difficult to cut the soles?

No, all you need is a pair of scissors. Our material cuts effortlessly.

What happens if I make a mistake on the cut-out?

We recommend making the cut a little larger so you can make adjustments easily. Cutting too small won't really affect performance as there are enough cells to ensure proper operation.

SoleCooler can't be held responsible for incorrect cutting, so if you're not sure, don't hesitate to contact us before your first cut.

How to clean and wash insoles?

Our products are easy to wash with soap and water. You can also use alcohol.
