A flexible innerduct structure (10) is configured to contain a cable within a conduit. The innerduct structure includes a pair of adjacent strip-shaped layers of flexible material (20, 22) that are joined along their longitudina l edges (24) to define a channel (14) through which the cable can extend longitudinally through the innerduct structure between the layers. The adjacent layers have differing widths between their longitudinal edges, whereby the wider layer bulges away from the narrower layer to impart an ope n configuration to the channel. Other features of the innerduct structure rela te to the material of which it is formed. Such features include the structure o f the material, such as a woven structure, and further include properties such as melting point, tensile strength, elongation, coefficient of friction, cri mp resistance and compression recovery.
