Desert Boots is an add-on that provides Magic +1, Spirit +1, Evasion +2, and halves Earth-elemental damage, as well as teaches Flee-Gil, Protect, and Scan. Though not mentioned in the menu, it also makes the wearer weak to Water.
Desert Boots are armor for the feet slot that are wearable at level 62 by all jobs. They have defense 11 and add 10 to HP and 1 to Agility. In sandstorms, they increase the wearer's movement speed by 12%. They are crafted using leathercraft from the skin of the Yowie. As a crafted item, they also have high-quality version, Desert Boots +1, which offer defense 12, HP +12, and agility +2 in addition to the same movement bonus. It used to be popular for scholars to use them as a low-budget form of Herald's Gaiters (which raise movement speed by 12% all the time) by casting Sandstorm on themselves to trigger the Desert Boots' effect.
