In chapter 16 of the book "Skáldskaparmál", a kenning given for Loki is "relative of Sleipnir." In chapter 17, a story is provided in which Odin rides Sleipnir into the land of Jötunheimr and arrives at the residence of the jötunn Hrungnir. Hrungnir asks "what sort of person this was" wearing a golden helmet, "riding sky and sea," and says that the stranger "has a marvellously good horse." Odin wagers his head that no horse as good could be found in all of Jötunheimr. Hrungnir admitted that it was a fine horse, yet states that he owns a much longer-paced horse; Gullfaxi. Incensed, Hrungnir leaps atop Gullfaxi, intending to attack Odin for Odin's boasting. Odin gallops hard ahead of Hrungnir, and, in his, fury, Hrungnir finds himself having rushed into the gates of Asgard. In chapter 58, Sleipnir is mentioned among a list of horses in "Þorgrímsþula": "Hrafn and Sleipnir, splendid horses [...]". In addition, Sleipnir occurs twice in kennings for "ship" (once appearing in chapter 25 in a work by the skald Refr, and "sea-Sleipnir" appearing in chapter 49 in "Húsdrápa", a work by the 10th century skald Úlfr Uggason).
