Sorry, no etymologies found.
Originally the sandals were called campagi, the stockings udones.
As regards the original form and material of the campagi, they were slippers that covered only the tip of the foot and the heel, and must have been fastened to the foot by straps.
Indeed this foot-covering was not reserved exclusively for the clergy, as not only the monuments show that the campagi and udones were worn by the laity, but Lydus also testifies to this usage
During the eighth and ninth centuries also the Roman subdeacons and acolytes wore a distinctive foot-wear, the subtalares, which, however, were simpler than the campagi, and had no straps.
In the earliest period the campagi and udones were by no means exclusively an episcopal ornament, as they were worn by deacons.
