It's time for these.

felted wool slipper from French Press Knits

Felted wool on the feet make the best slippers. I had some felted wool bootie slippers and like a fool I washed them, they were terribly dirty and I thought I'd remember NOT to put them in the dryer, but I never remember to not put the thing I should not put in the dryer in the dryer and thereby have ended up with felted bootie slippers for an elf (they were green). Now I need new ones and am on the hunt. These are way cute and on Etsy, where I buy pretty much everything...
