Jet Skis are elongated U-shaped black footwear, with a Breath Dial installed into the middle sides, which serves as the main power source. They are worn on each foot, and resemble a pair of ice skates.
The Jet Skis allow the wearers to travel on Sea Clouds on foot, in a fashion similar to ice skating on ice. Breath Dials serve as the power source, which acts a propulsion device. The White Berets were able to combine these skis with the streams created by their Milky Arrows to confuse and capture their enemies. Wiper equipped his skis with seastone, enabling him to negate Devil Fruit powers.
