Cain's Travelers are a Boots piece of the Cain's Destiny crafted set in Diablo III. They require character level 70 to be equipped. The level 23 crafted equivalent are Cain's Sandals.
Deckard Cain spent the last twenty years of his life traveling the world in search of information needed to defeat the Lords of Hell.
Cain's Travelers can be crafted using the Plan: Cain's Destiny, 72000 gold, 30 Reusable Parts, 30 Arcane Dust, 50 Veiled Crystals, Caldeum Nightshade and Corrupted Angel Flesh.
Prior to Patch 2.0.6., they also required Maghda's Tormented Soul, obtained from Maghda.
