G-heat heated insoles: the end of numb fingers/toes from cold feet on the bike

While winter is starting to draw to a close, the cold remains very much present. And it will inevitably return. Every year, it pushes many cyclists to put away their bikes in favor of the indoor trainer, facilitated by the democratization of connected platforms. Yet, nothing truly replaces the sensation of the asphalt, the precision of steering, and the pleasure of a real outdoor ride. In 2025, solutions to combat the cold exist and are effective. Today, we’re talking about an innovation from G-heat, a world leader in heated clothing: heated insoles with external batteries. We tested them.

Why be interested in heated insoles?

Living in Grenoble, I know how challenging it can be to ride in sub-zero temperatures. Layers of technical socks, high-end shoe covers… nothing ever seems to be enough. Sooner or later, toes end up petrified by the cold, making the ride as uncomfortable as it is short.

With these Gheat heated insoles, everything has changed. More than just an accessory, they have transformed my approach to winter cycling.

Technology adapted to cyclists’ needs

Gheat, a French company founded in 2017 and specializing in heated equipment for athletes, has successfully established its expertise. While heated insoles have long existed in skiing, few solutions adapted to cycling had truly emerged until now. We had already tested models from the Sidas brand, which were effective but still far from optimal comfort. With Gheat insoles, we are clearly taking a step forward.

The model tested here is the one with an external battery, an obvious choice to maintain a low insole height and natural pedaling sensation.

First good surprise: comfort. The insole is pleasant underfoot and adapts particularly well to pronounced arch supports. Once the size is chosen (to be adjusted with scissors using the original insole as a guide), simply install it in the shoe.

The wire connecting to the battery discreetly exits at the outer malleolus. Well thought out for cycling use.

The batteries attach with a supplied strap, but let’s be honest: this solution is not ideal for cycling. I preferred to slip them under the shoe cover or between the sock and the tights. In this configuration, no discomfort was felt.

Adjustable and durable warmth

Three heating levels are available:

• 40°C – 11h30 autonomy
• 45°C – 7h30 autonomy
• 55°C – 6h autonomy

Adjustment is made via a mini remote control, which can easily be slipped into a pocket. We’re already dreaming of a version connected to our bike computers… But for now, it remains a simple operation.

Pairing with the batteries requires a little attention, but once configured, everything works perfectly.

Small tip: do not leave the remote control in your jacket after the ride. It risks ending up in the washing machine (personal experience… unusable afterwards).

Another interesting point: the batteries use the same connection standard as Gheat heated gloves. If needed, it is therefore possible to interchange power between hands and feet. Appreciable flexibility to adapt to the day’s conditions.

On the road: a revelation

From the very first pedal strokes, the thermal comfort is striking. Even on long rides exceeding 7 hours in freezing temperatures, my feet were never cold, and this was while staying on mode 1 (40°C). Even better, without even activating the heating, the insole itself already provides additional insulation thanks to its materials.

They also offer battery-free, natural wool heated insoles https://www.g-heat.com/products/semelles-laine

With such equipment, dry cold is no longer a problem. Of course, the question of whether roads are passable or not remains, but for those who dare to ride in winter, this solution is a game-changer.

We unhesitatingly recommend these insoles to all cyclists who want to enjoy the cold season without suffering from the cold. In 2025, there’s no longer any excuse to put away your bike at the first frost.

At €99.90 per pair of insoles, the investment should interest most cyclists! Unfortunately, at the time of writing, the product is no longer in stock. But this should be resolved soon. Perhaps the internal battery model will be offered to us for testing soon for comparison? We hope so!
