This Viberg x Jason Jules (Garmsville) collaboration puts a brogued upper on the round-toe Navvy Boot last — referencing vintage US Navy patterns — in C.F. Stead Janus Calf Suede, with a 270° antique flat welt and an oak-bark-tanned leather sole. Broguing on a Navvy last is the whole idea: it bridges military utility and English dress heritage in a proportion Jules pulled from his own archive.
