The Nike Air Max Pre-Day 'Smoke Grey' is a lifestyle runner that draws inspiration from Nike's rich running heritage. With its neutral colorway, this shoe showcases an array of grey shades that cover its layered upper, which incorporates a durable textile base made entirely from 100% recycled polyester. The deconstructed aesthetic is further enhanced by the exposed zigzag stitching and a floating eyestay, cleverly secured with stitched bar tacks. Delivering a comfortable experience, the shoe boasts a lightweight foam midsole that offers responsive cushioning and houses a fully exposed Air-sole unit in the heel area. The underfoot features a waffle-traction rubber outsole that not only provides excellent grip but is also partially made from Nike Grind, further emphasizing the brand's commitment to sustainability.
