Ninja Sandals

The Ninja Sandals are Boots introduced in Golden Sun: Dark Dawn. Like most Boots, they can be equipped by any party member. The Ninja Sandals are also Artifacts, meaning they can be repurchased from any armor vendor if they are dropped or sold. On that note, the Ninja Sandals can be bought for 2000 coins and sold for 1500.

In battle
The Ninja Sandals increase the wearer's Defense by 19 and increase the chance that a weapon will Unleash by 15%, making them the Dark Dawn successor of the Hyper Boots.

The Ninja Sandals can be used as part of a set up to increase the Unleash rate of the Sol Blade. Combining the Ninja Sandals with the Valkyrie Mail, Aegis Shield, Warrior's Helm, and the Lord Sun's Ring allow for an almost-100% Unleash rate. However, due to the revisions to the Unleash system, the Unleash may be any of the Sol Blade's Unleashes, rather than just Megiddo.

Acquiring the Ninja Sandals
In order to get the Ninja Sandals, players must first acquire the Grandmother's Gift from a woman in Kaocho and deliver it to her granddaughter in Tonfon. The granddaughter will give players the Granddaughter's Gift in exchange. Upon returning to Kaocho, players will discover that the grandmother was a casualty of the Grave Eclipse. Placing the gift next to her will allow the grandmother's spirit to respond and enter the afterlife. Afterwards, examine the package to discover a letter which instructs the Grandmother to give the player the Ninja Sandals as a thank you.

It should be noted that, due to the Grave Eclipse, players cannot acquire the Grandmother's Gift after crossing the Clouds of Passaj. As a result, it is possible to lose the Ninja Sandals forever.

Trivia

 * Although they weren't officially introduced until Dark Dawn, the Ninja Sandals were coded into Golden Sun: The Lost Age, although they couldn't be accessed without a hacking device. It is likely that the Ninja Sandals, along with the Knight's Greave and the Silver Greave, were meant to be new prizes at the Lucky Wheels minigame, but were removed in favor of the first game's prizes.
 * In The Lost Age, the Ninja Sandals only offered a Defense increase of 5, in addition to the Unleash rate boost. Despite this, they were superior in every way to the Hyper Boots, which, ironically, cost more than the Ninja Sandals.
