The versatility of the iconic Air Max 90 continues to allow Nike to recreate the shoe in new and interesting ways, and with 25 years already under its belt it seems like its not slowing down anytime soon. The latest iteration of our beloved AM90 is the Vac-Tech models that have started appearing at Nike accounts across the world. First we saw the sleek 'Gorge Green' colourway hitting shelves in Europe, and now Nike have followed up with the bold 'Varsity Maize' version that looks like the product of some heavy petting between a gumboot and a trainer. The all-yellow upper is contrasted with a black heel shield and tongue patch, all above a white midsole. If you like what you see, head to Shelf life's online store now to pick up.
