The hindlimbs of "Suchomimus" and "Baryonyx" were somewhat short and mostly conventional of other megalosauroid theropods. "Ichthyovenator"'s hip region was reduced, having the shortest pubis (pubic bone) and ischium (lower and rearmost hip bone) in proportion to the illium (main hip bone) of any other known theropod. "Spinosaurus" had an even smaller pelvis and hindlimbs in proportion to its body size; its legs composed just over 25 percent of the total body length. Substantially complete spinosaurid foot remains are only known from "Spinosaurus". Unlike most theropods—which walk on three toes, with the hallux (first toe) being reduced and elevated off the ground—"Spinosaurus" walked on four functional toes, with an enlarged hallux that came in contact with the ground. The unguals of its feet, in contrast with the deeper, smaller and recurved unguals of other theropods, were shallow, long, large in relation to the foot, and had flat bottoms. Based on comparisons with those of modern shorebirds, it is possible that "Spinosaurus"'s feet were webbed.
