A impressive, yet plain model is the Air Jordan 4 (IV) Retro Black Cats, which sold well for adults and kids. The Air Jordan IV makes its fourth retro run with the start of the new Black Cat" theme - Inspired by MJ's nickname given to him by his Chicago Bulls teammates describing his playing style. The theme is usually represented by an all black-based sneaker. These also took a $5 price increase and retailed at $115 rather than the $110 price tag from the 2004 Air Jordan 4 Retros. Also, if you flip the mudflap back, you'll see the words "Black Cat" stitched on it."
