How long does the battery last on one charge?

The slippers are rated for up to 11 hours, though the top 140°F setting will drain the batteries faster than the low setting.

Three settings span roughly 100°F to 140°F. The heating element sits at the bottom of the foot near the sole and toes.

Can I wear them outside?

They have non-slip rubber treads, but they are not water resistant, so wet pavement, snow and slush will soak the polyester upper.

Are the batteries included?

Yes. Each slipper runs on a 7.4V rechargeable lithium-polymer battery, and a pair comes in the box.

Will they help with Raynaud's syndrome or poor circulation?

Buyers with Raynaud's and cold feet say the steady heat helps. It is a comfort product, not a medical treatment, so check with a doctor for circulation problems.

How do they compare with plug-in heated foot warmers?

These are cordless and rechargeable, so you can walk around, but they need recharging and are not water resistant. Corded warmers run indefinitely but tie you to an outlet.

Buyers who left feedback mostly have circulation problems, and they say the slippers warm numb, white toes quickly and keep working where other heated products failed. They also report the heat lasting a long time. The main complaint is that the heat stays in the slipper rather than moving into shoes.
