I have these! But a less puffy version I guess? They are SO WARM AND COSY and have a proper sole so you can take the bin out and that without having to get proper shoes on.
(excuse the tea splodges, I’m too lazy to keep them clean)
They look very silly but as a WFHer for 6 years now who gets cold easily they are the only thing that keep my feet warm
Edit: oh god they are so dirty, sorry DiS
