I have tinfoil-lined slippers slippers so the NSA can't read what my toes are thinking!
I usually pad around here in fleecy socks with big polka-dots but the hardwood floors of Roseholme Cottage can get a mite chill this time of year. No, seriously: my hands encounter a noticeable thermocline when I'm doing toe-touches during the morning physical jerks. There could be Russkie boomers lurking at ankle height and my sonar would never spot them.
I needed slippers that were warm, easy to step in and out of, and with a sole that could handle stepping outdoors at this time of year, with enough texture to prevent pratfalls but without so much texture that any snow inadvertently picked up wouldn't get scraped off with a quick scuff on the sisal doormats. These deliver. And boy howdy are they toasty snuggly warm.
I went with the dude's slippers in black because they look more carbon-fiber-y and you want your house slippers to be all ninja and stuff, but the more traditional-looking women's ones are muy cheaper in some colors. (I've never thought that house slippers, like bathrobes, were particularly gendered articles of clothing anyway; you rock out whatever's coziest, and if it expresses your essential "you-ness" then, hey, bonus.)
