The problem
Thick socks don’t fix cold feet.
Wool socks and insulated boots only hold the heat your body makes. Stand still on a job site, a frozen lake or a concrete floor, and that heat runs out. Your toes go first.
How it works
Three steps. No tools.
STEP 01
Trim
Cut along the printed size lines to match your shoe.
STEP 02
Charge
Plug in the included USB-C cable. Full charge in about 3 hours.
STEP 03
Click
Pick low, medium or high from the remote — no boots off.

Questions, answered.
How long does the battery last?
Up to 8+ hours on low per charge. Each insole has its own 2000mAh rechargeable lithium-ion polymer battery, rated for 500+ charge cycles.
Will they fit my shoes?
They trim to fit and replace the insole already in your sneakers, hiking boots or work boots. They’re about 5 mm thick at the forefoot and 8 mm at the heel.
Which size do I order?
S fits EU 34–40 (men’s 3.5–7.5, women’s 5–9). M fits EU 40–46 (men’s 8+, women’s 9.5+). Pick your size, then trim along the printed lines to match your shoe.
Where does the heat go?
The carbon-fiber heating element covers your whole forefoot, where toes and the ball of your foot lose heat first.
What’s in the box?
A pair of heated insoles, a wireless remote, a USB-C charging cable and a user manual.
How long to charge?
About 3 hours with the included USB-C cable (5V/1A).
Are they safe?
Max temperature is 140°F (60°C). They have overheat protection with auto shut-off, short-circuit protection and certified lithium-ion cells.
Can I get them wet?
They’re rated IPX4, so snow, slush and wet boots are fine. Don’t submerge them or put them in the washer.
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.
Our promise
Warm feet, or your money back.
30-day returns. Free US shipping on every order.
