LE Soccer Shoes

The item was called LE Soccer Cleats in Splatoon.

Appearance
The LE Soccer Shoes are a pair of shiny gray cleats with blue spikes and red-orange laces. They have extended tongues with a small black Takoroka logo each, and the laces are off-center, angled outward. On either side of each shoe is a slightly modified version of the Takoroka logo in dark gray, with a similarly-colored Inkling word printed vertically in on the heel. They come with a pair of long burgundy socks with another Takoroka logo around each one, this time in a dull yellow.

Splatoon 3
The LE Soccer Shoes can be seen in a Twitter post for the Splatoon 3: Expansion Pass. They can be seen being worn by an Inkling on Inkopolis Plaza.
