Black Seahorses

Appearance
The Black Seahorses are a pair of black sneakers with white soles and the arrow from the Zink logo, also in white, on both sides. On the tongue is the full Zink logo in black and white. There is also a small section of white just above each heel.

Splatoon 3
The Black Seahorses can be seen in the Splatoon 3: Expansion Pass trailer. They can be seen being sold in Shrimp Kicks.

Trivia

 * The Black Seahorses' Japanese name, "Seahorse Black Leather", suggests that they are made of leather. However, the other Seahorses do not have "leather" in their Japanese name, only their color.
