Don't walk in them.
Nice while they lasted. Alas when I disconnected them to go the the restroom, one of the wires sticking out of the slipper caught on the door, tripped me and ripped the wire off the heating pad.  So now I can only heat one foot at a time.  Kinda of defeats the purpose and I don't see anywhere on Amazon a replacement pad can be purchased.  Oh well.  They really should make the heating pads available for replacement.  I can't be the only one this has happened too.
