The gold glimmer of a vintage Nike track shoe caught my eye as I passed by the front window of Amsterdam's premier sneaker boutique Seventy Five. Unfortunately, they weren't open, but the time I spent with my face pressed against the window admiring the collection of vintage, one-off, and foreign sneakers was worth it. A rainbow of colored Nikes, Adidas, and Asics litter the shop, but it is the monochromatic Rucanor F24 that is the real prize. Distributed to only 3 shops in the Netherlands, of which Seventy Five is the only in Amsterdam, the rare F24 makes a nice addition to any sneaker connoisseurs collection. Look for the Rucanor Kansas canvas high-top sneaker and Rucanor Netcourt badminton sneaker early next year at where else, but Seventy Five!
