Heat on tap, three ways
A round button on the outer side powers each slipper on and cycles three warmth levels. The LED ring glows red, blue or green so you always know where you are set.
- ✓Red = high, fastest warm-up
- ✓Blue = steady all-day warmth
- ✓Green = gentle, battery-saving heat

Plush that wraps your whole foot
A thick, high-density faux-fur lining cushions every step and traps warmth around the entire foot — not just the sole. Soft suede-look upper, breathable, never stuffy.

Questions, answered
How long does the heat last on a charge?
Depends on your setting — low (green) lasts longest, high (red) warms fastest. Recharge the power bank over USB-C whenever you need a top-up.
Are they safe to wear for a long time?
Yes. They run on a low-voltage rechargeable power bank (not wall current) with gentle, even warmth. Start low or medium and tap off whenever you like.
Can I wear them without the heat on?
Absolutely — the thick plush lining makes them cozy on their own. The heat is there for an extra boost.
How do I choose a size?
Fit is unisex. Between sizes or wearing thick socks? Size up for the roomiest feel.
How does charging work?
The power bank charges over the included USB-C cable from any phone charger. Once charged, slot it into the slipper's side pocket and you're set.
