Paying tribute to the £100 bill, the 577 'English Tender' Red features a mesh-based upper with matching suede overlays on the toe box and side panel. The sneaker also boasts synthetic grey accents on the eyestay, black suede detailing on the heel, and a light grey leather heel collar. To further the theme, the sneaker features a custom insole, a £ sign on the tongue, and is manufactured in the Flimby factory in the UK.
