The Nike M2K Tekno Atmosphere Gray is part of the M2K Tekno series, which is a spinoff of the Nike Air Monarch. <br> <br> The upper of the M2K Tekno Atmosphere Gray is made from a combination of materials, including synthetic leather, mesh, and textile. The tongue is padded, which helps to prevent chafing, while the collar is designed to fit snugly around the ankle, providing added comfort and support. The shoe has a predominantly Atmosphere Gray colorway, with Gun Smoke and white accents. The outsole is made from a durable rubber material that provides stability and ensures a secure and confident stride, even on slippery and uneven surfaces. <br> <br> We think that the standout feature of the Nike M2K Tekno sneaker is its chunky midsole, and more specifically, its sizable appearance. The midsole is thick, providing an extra layer of cushioning and support, making it an ideal shoe for high-impact activities, like running, exercising, and long periods of walking or standing. The Nike M2K Tekno Atmosphere Gray was released on December 1st, 2018, at a retail price of $130.
