Inspired by the brand’s original City Series, the adidas Frankfurt ‘Bluebird’ features a design based on the ‘80s adidas Hamburg. The blue suede upper, secured with a trio of adjustable straps in lieu of traditional laces, features various metallic silver branding elements, including serrated leather three-stripes and a printed tongue tag. A semi-translucent rubber cupsole anchors the low-profile silhouette.
