Wearable disposable absorbent articles such as disposable diapers, having elastically extensible fastening members (also sometimes known as fastening &ldquo；ears&rdquo；) with particular features, extending from a chassis or main portion of the articles, are disclosed. The fastening members may be highly extensible and have an overall geometry, characterized by greater length nearer the chassis or main portion and lesser length nearer the distal end. Examples disclosed may have a fastener zone having a Stiffness of at least about 1,500 N/m, and shape and dimensional characteristics, that help avoid problems of buckling and/or flipping of edges of the fastening members, dishing of fastener components, and fastening member tearing, while the articles are applied and worn.
