Yes it is an insulator but you are completing the circuit (through your body) with the ring main (parallel circuit) of the house. The floor has nothing to do with it. You would still get the shock if you were floating in thin air wearing rubber socks!

Do you mean static?
The accumulation of excess electric charge in a region with poor electrical conductivity (an insulator), such that the charge accumulation persists. The effects of static electricity are familiar to most people because we can see, feel and even hear the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example a path to ground), or a region with an excess charge of the opposite polarity (positive or negative).
