The Air Jordan 4 Retro 'Cool Grey' 2019 celebrates the iconic silhouette's 30th anniversary with an updated take and a Cool Grey, Chrome and Dark Charcoal colourway. Released in August 2019, this sneaker pays tribute to the original with prominent Jumpman branding, plastic lace locks and a leather and synthetic upper. Rounding out the style of this classic model is a visible Air-Sole unit in the heel and an outsole with a herringbone pattern for traction.
