Got Questions?
We’ve got answers.
Do they fit my shoe size?
Cut-to-fit, UK 2-12.5 / US 4-13 / EU 35–46.
Do they fit my shoe size?
Cut-to-fit, UK 2-12.5 / US 4-13 / EU 35–46.
The ToastyBody Heated Insoles are one size with trim lines so you can cut the toe area to your exact size. They cover approx. UK 2-12.5 / US 4-13 / EU 35–46. Use your current insole as a guide, trim only at the toe along the printed lines, and do not cut into the wiring or beyond the last guideline.
Are batteries included?
No, use any 5V USB power bank.
Are batteries included?
No, use any 5V USB power bank.
A power bank isn’t included. The insoles run from a standard 5V USB power bank via the included USB cable. We recommend our 10,000 mAh ToastyBody Power Bank for reliable all-day warmth. Route the cable up your ankle into a pocket or clip the bank to a boot/shoe strap for a tidy setup.
How warm do they get, and how fast?
Warmth in ~60s, up to ~50–55 °C (122–131 °F).
How warm do they get, and how fast?
Warmth in ~60s, up to ~50–55 °C (122–131 °F).
The carbon-fiber elements heat within about a minute. At the element surface they can reach roughly 50–55 °C (122–131 °F); the warmth you feel inside the shoe is lower and depends on sock thickness, shoe insulation, and outdoor temperature, designed to keep toes comfortable, not sweaty.
How long does the heat last?
Up to 10 hours.
How long does the heat last?
Up to 10 hours.
Runtime varies with your power bank and conditions. As a guide, a quality 10,000 mAh bank can deliver around 10 hours of gentle warmth. Colder weather, higher output banks, and frequent on/off cycles will change that. For longer days out, bring a spare bank or top up between sessions.
Will they fit in my shoes/boots?
Low-profile; remove stock insoles.

Low-profile; remove stock insoles.
The insoles are slim and designed to work in most trainers, boots, and ski/snowboard boots. For the roomiest fit, take out the shoe’s original insole and replace it with the Heated Insole. If you rely on an orthotic, you can sometimes layer the Heated Insole beneath it if there’s space, otherwise size up the footwear by half a size.
Where do they heat?
Forefoot & toe zone.
Where do they heat?
Forefoot & toe zone.
Heating elements focus under the forefoot and toes (areas most prone to getting cold). This design keeps warmth where it matters while letting the rest of the foot breathe. Heat then diffuses through the insole and your sock for an even, gentle feel.
Are they safe and water-resistant?
Low-voltage 5V, splash-resistant.
Are they safe and water-resistant?
Low-voltage 5V, splash-resistant.
They run on safe low-voltage (5V) USB power and include built-in protection. The insole body is water-resistant for everyday use, but avoid soaking or submerging and keep connectors dry. Always disconnect before removing shoes and before cleaning.
How do I clean and care for them?
Brush/wipe clean, air-dry fully.
How do I clean and care for them?
Brush/wipe clean, air-dry fully.
Disconnect the power bank, then wipe the surface with a damp cloth or use a soft brush with mild soap for stubborn dirt. Do not machine-wash, bleach, tumble-dry, or wring. Let them air-dry completely before next use to protect the electronics and maintain performance.
