- How do the Warmies Marshmallow slippers heat up?
- They use a removable insert that you warm in a microwave, then place back into the slipper. The warmth comes from that insert, not from a battery or plug.
- Can I wear them outside?
- No. They are house slippers with a soft fur upper and faux-fur lining, so they are meant for indoor floors.
- What sizes and colors are available?
- They come in adult sizes in pink and gray. Check the size chart before ordering, since slipper sizing can run differently from shoe sizing.
- How do I clean them?
- Remove the heatable insert first. Spot clean the fur upper and let the slippers air dry; do not machine wash the insert.
- Is $29.99 a good price?
- Warmies lists them at $29.99 as of November 8, 2026, and it is the only new-price listing we have. With one store, there is no lower competing price to beat it.
- Are they worth it?
- If you want slippers that warm up before you put them on, the heatable insert is the main draw. If you just want plain house slippers, a standard pair costs less.
- Where is the Warmies Marshmallow Gray Heatable House Slippers cheapest?
- At Warmies, for $29.99, as of our latest check.
