Don’t wear The rock dove slippers to bed but I do use a ‘Foot of Bed’ heating pad from Cozy Winters online. It’s long Enough to go across almost half of the bed so I Can move around. It has a long cord and the adjustable control reaches up to pillow. Six hour auto shut off allows me to keep feet warm most of the night. About $55 but I couldn’t sleep without it so worth every penny. During the winter with all night, every night use it lasted 3-4 months. I now keep an extra on hand in case it goes out middle of the night. Wishing you warm feet, Bcool123
