Slippered → It is formed from "slipper" (from Middle English *slipere*, meaning a light shoe that slips on easily) and "-ed" (a suffix used to form the past tense or to indicate a state). The word "slippered" means being in a state of wearing slippers or having slippers on.
Think of a light shoe that 'slips on easily' — that's what a slipper is, and when you are 'slippered', it means you are wearing them.
