Well, depends on your definition of relatively smooth. Also what you're comparing it to. Hobnails have a poor coefficient of friction on most surfaces, but make up for it by catching in dents and holes in the surface, either preexisting or (in the case of soft surfaces) made by the hobnails, so they're heavily dependent on just how uneven the surface is.
Note, also, that hobnails on smooth relatively soft surfaces (such as wood) do this by damaging the surface, thus making them unwelcome. In general if you
aren't damaging the flooring, you'll be slipping about indoors.
