The problem

Thick socks don’t fix cold feet.

Wool socks and insulated boots only hold the heat your body makes. Stand still in the cold long enough and that heat runs out. Your toes go first.

  • Concrete floors and frozen ground pull heat out of your feet.
  • Disposable heat packs run out and end up in the trash.
  • EmberSole™ adds real, adjustable heat right under your toes.

FAQ

Questions, answered.

How long does the battery last?

Up to 8+ hours on low per charge. Each insole has its own 2000mAh rechargeable battery, rated for 500+ charge cycles.

Will they fit my shoes?

Yes. Pick S (EU 34–40) or M (EU 40–46), then trim along the printed lines. They replace the insole in your sneakers, hiking boots or work boots.

How do I control the heat?

One wireless remote controls both insoles: low, medium or high, from about 50 ft away.

Are they safe?

Max temperature is 140°F (60°C), with overheat protection (auto shut-off) and short-circuit protection. They’re rated IPX4 for snow and slush.

When will it arrive?

Orders are processed within 1 business day and delivered in 7–9 business days. Shipping is free on every order.

What if they don’t work for me?

Return them within 30 days.
