rubber-soled

the compound adjective 'rubber-soled' is a modern english formation that transparently describes a functional attribute of footwear. its first element, 'rubber', originates from the material's use for erasing pencil marks by rubbing, a term coined in the late 18th century. the second element, 'sole', has a long lineage from latin 'solea', referring to a sandal or the underside of the foot, entering english via old french. the combination, finalized with the adjectival suffix '-ed', literally means "provided with a sole made of rubber," directly linking the material's properties (elasticity, grip) to the part of the shoe that contacts the ground.
