Ink-Black Clam 600s

SplatNet 3 calls this item Ink-Black Clam Dunks.

Appearance
The Ink-Black Clam 600s are a pair of light black shoes with mollusc resembling elements. Consisting of various layers and patches, Clam 600s have mostly smooth texture, accompanied by pieces of red mesh on the sides. The front consists of a black mesh partly covered by layers of suede fabric, featuring accented eyelets and dull black laces, tied visibly wishy-washy. The soles are mostly dark gray clam-like discs, attached to a pitch black base, in addition of a sharp-edged outsole made from the same material.

Trivia

 * As recently as version 1.1.2, when viewing players in the Square, this item was named as Ink-Black Clam 600s. But is still called its original name in SplatNet3.
