The adidas Ultra Boost Gore-Tex Underground Pack was designed by Ben Herath and draws inspiration from the underground culture devoted to the grit of London. The Underground comes in a core black and red colorway, featuring white and yellow accents. The upper is mainly made using black Gore-Tex knit, supported by a cage with 3-Stripe overlays on the quarter panels, a PU heel counter, and a layered mudguard, all in black. A black heel tab is stitched at the heel with three white stripes, and a red toggle is fitted on the tongue with black laces going through punched eyelets for closure. The sneaker sits on ultraboost cushioning with a yellow accent on the heel next to the waist. StockX experts appreciate the triple black with yellow and red accents symbolizing London in the shoe’s design, a subtly meaningful element. The Underground was released on 17th December 2021 for $180.
