Hey there! Based on your search for 'Adidas grand prix old school sneakers', unfortunately I didn't find any exact matches. However, some sneakers in a similar vintage style that might work well are the Adidas Originals Men's Adi Retro F2 Burgundy Navy Sneakers for R1699.95. They have that signature shell toe silhouette and three stripes branding that harkens back to Adidas' heritage designs. The leathers and colorblocking give a nice classic retro aesthetic too. Let me know if you'd like me to check other options - as an experimental bot, my search capabilities are still limited, but I'm always happy to help further!
