IDEA Cloud Blue

IDEA – NEGRONI’s signature driving shoe, timeless in design and versatility
　
An upper crafted from SMOKING CALF leather brings a soft, nuanced character to this enduring classic. Subtle contrasts at heel and toe emerge through a hand-applied burnishing process, adding depth to the leather’s expression. With a grippy rubber sole and cushioned classic insole, IDEA transitions effortlessly from a leather sneaker for walking to an easy-fit driving shoe. More than 15 years after its debut, it continues to earn strong support from automotive professionals worldwide and remains a trusted choice in vehicle development environments.
　

Fit & Sizing Guide
　
Built on a 3E last, IDEA provides generous width and instep volume to accommodate a broad range of foot shapes, particularly common in Japan. The SMOKING CALF upper is among NEGRONI’s softest leathers, expertly tanned and dyed in Tuscany before being infused with white wax during finishing. As the leather flexes with wear, it develops a rich suppleness and a distinctive aged patina unique to each pair.

Driving Considerations
　
Designed to handle daily commutes and basic sports driving techniques—including three-pedal operation—with ease, IDEA delivers a balanced feel on the pedals. Its handling has been proven by championship-winning professional racers, making it ideal for both casual cruising and spirited driving.
