These are very comfy, probably best for a narrow foot. There is a lot of foot coverage, just FYI. They will
keep you warm! They are so padded, and super awesome grippy rubber thick
sole - the kind you can go water plants in. I wear a size 10.5 and these fit, but no extra room in the length! So if you're 10.5 or bigger, it might be iffy. I tried the smart dogs "Joy" slippers too - more traditional/conservative, but also super comfy, and very plush. Dog hair sticks less to the "Comfy" ones. Both great!
