The Nike Air Max 90 Premium "Tiempo" takes inspiration from the classic football boot, worn by Ronaldinho in the 2005 "Crossbar" video that became the first video on YouTube to reach one million views. The usual mesh is almost entirely replaced by smooth black leather, with diamond-shaped stitching across the front referencing the 2005 Tiempo. A white Swoosh sits against the black leather, with small Volt and purple details on the tongue and around the Air unit, while a black midsole is paired with a brown gum outsole.
