The adidas Campus 00s 'Grey Gum' features a grey suede upper, lined in terry cloth and accented with white serrated leather three-stripes. Trefoil branding graces the padded tongue and back tab, while 'CAMPUS' is stamped on the lateral side. The sneaker sits atop an off-white rubber midsole built with stitched sidewall construction. A herringbone tread gum rubber outsole provides grippy traction underfoot.
