These Doctor Who slippers may not be "bigger" on the inside, but they are comfortable — perfect for those days when you're marathoning classic episodes and daydreaming about your own trips through all of time and space.
Keep your feet warm and protected and your head in the stars with these very special TARDISes: that's Time And Relative Dimensions in Shoes, of course. Please note that the listed sizes are all the same style.
