The Ember Heating Insole

Warm feet, no bulk, no fuss.

The insoles that turn any pair of boots into cold-weather boots.
Built with dedicated heating zones at the toe and heel, The Ember Insoles slide into almost any shoe or boot and connect to a standard USB power source, adding real warmth underfoot without changing how the shoe fits or feels. For the mornings when the cold gets in before you’re even out the door.

Key Benefits
• Dual heating zones, toe and heel
• Cushioned footbed, comfortable all day
• USB powered, works with any power source
• Two size bands, fits most footwear

What It Is
The Ember Insoles are a slim, cushioned footbed with heating elements built into the toe and heel zones, connected to a simple USB cord that plugs into any standard power source — a power bank, a wall adapter, or a laptop. They sit inside the shoe like a normal insole, adding warmth without adding bulk or changing the fit of the boot around them.
Available in two size bands to suit a wide range of foot sizes, finished in a deep charcoal-black that stays out of sight once inside the shoe. Built for the boots that see the most cold-weather wear — the ones for the school run, the commute, the dog walk before the sun is properly up.

How It Works
• Heating elements built into the toe and heel zones for even, full-length warmth
• Cushioned top layer adds comfort without raising the shoe’s internal fit
• USB cord connects to any standard power source for heating
• Insulated base layer helps retain warmth rather than losing it into the sole of the shoe
• Slim profile designed to sit inside most boots and shoes without crowding the fit

What to Expect
• Warmth building at the toe and heel within minutes of connecting power
• A footbed that still feels like a normal insole, not a bulky insert
• No change to how snugly your usual boots fit
• Consistent warmth through a full walk or a full day at a desk
• A cord that tucks away rather than getting in the way

A Cold Morning, Solved Before You Leave
There’s a particular kind of cold that sits in the soles of your feet before you’ve even stepped outside — the kind ordinary socks never quite fix. The Ember Insoles are built to solve that before it starts. Connect the cord for a few minutes before you leave, and the toe and heel are already warm by the time the boots go on, rather than slowly catching up to the cold once you’re already out the door. It turns getting ready into part of the warming process, not an afterthought to it.

Warmth That Reaches Where It’s Needed
Cold feet rarely go cold all at once — it’s almost always the toes and heel first, the two points that touch the ground and the two points furthest from the body’s own circulation. That’s exactly where the heating zones sit, rather than spreading warmth thinly and evenly across the whole footbed where it isn’t actually needed. The result is warmth concentrated at the two points that matter most, so the difference is felt immediately rather than gradually, and the rest of the insole stays slim enough that the boot still fits the way it always has.

Built Into Boots You Already Own
The best version of this product is the one that disappears into a boot you already trust, rather than asking you to buy a whole new pair to get the benefit. The Ember Insoles are cut to a slim, cushioned profile specifically so they slide into your existing boots or shoes without crowding the toe box or changing the fit around the ankle. There’s no bulky insert to work around and no new pair of boots required — just the boots already by the door, now doing more for the cold than they did before.

FAQs
What size should I order?
The Ember Insoles come in two size bands — Small/Medium fits sizes 6–9, and Large/X-Large fits sizes 9.5–12. Check the size chart before ordering if you’re between the two.
How do they power on?
Connect the built-in USB cord to any standard USB power source — a power bank, wall adapter, or laptop — before putting the boots on. There’s no separate battery pack to charge ahead of time.
Will they fit inside my regular boots?
Yes, in most cases. The Ember Insoles are cut to a slim, cushioned profile designed to sit inside a normal boot or shoe without meaningfully changing the fit. Very narrow or tightly fitted footwear may feel slightly more snug once the insole is in.
How do I care for them?
Wipe clean with a damp cloth. Avoid submerging the insoles in water or machine washing, since the internal heating elements and cord connection are not designed for that kind of exposure.
Do they heat the entire foot or specific areas?
The heating zones are concentrated at the toe and heel, the two areas that typically get cold first and lose the most warmth, rather than spreading evenly and thinly across the whole footbed.

What’s Included
• One pair of Ember Insoles, in your selected size band
